   Gnulib is a source code library. It provides basic functionality to
programs and libraries.  Currently (as of October 2006) more than 30
packages make use of Gnulib.

1.1 Benefits of using Gnulib
============================

   Gnulib is useful to enhance various aspects of a package:

   * Portability: With Gnulib, a package maintainer can program against
     the POSIX and GNU libc APIs and nevertheless expect good
     portability to platforms that don't implement POSIX.

   * Maintainability: When a package uses modules from Gnulib instead
     of code written specifically for that package, the maintainer has
     less code to maintain.

   * Security: Gnulib provides functions that are immune against
     vulnerabilities that plague the uses of the corresponding
     commonplace functions. For example, `asprintf',
     `canonicalize_file_name' are not affected by buffer sizing
     problems that affect `sprintf', `realpath'.  `openat' does not
     have the race conditions that `open' has. Etc.

   * Reliability: Gnulib provides functions that combine a call to a
     system function with a check of the result. Examples are `xalloc',
     `xprintf', `xstrtod', `xgetcwd'.

   * Structure: Gnulib offers a way to structure code into modules,
     typically one include file, one source code file, and one autoconf
     macro for each functionality. Modularity helps maintainability.

1.2 Library vs. Reusable Code
=============================

   Classical libraries are installed as binary object code.  Gnulib is
different: It is used as a source code library.  Each package that uses
Gnulib thus ships with part of the Gnulib source code.  The used portion
of Gnulib is tailored to the package: A build tool, called
`gnulib-tool', is provided that copies a tailored subset of Gnulib into
the package.


File: gnulib.info,  Node: Portability and Application Code,  Next: Target Platforms,  Prev: Library vs Reusable Code,  Up: Introduction

1.3 Portability and Application Code
====================================

   One of the goals of Gnulib is to make portable programming easy, on
the basis of the standards relevant for GNU (and Unix).  The objective
behind that is to avoid a fragmentation of the user community into
disjoint user communities according to the operating system, and
instead allow synergies between users on different operating systems.

   Another goal of Gnulib is to provide application code that can be
shared between several applications.  Some people wonder: "What? glibc
doesn't have a function to copy a file?"  Indeed, the scope of a
system's libc is to implement the relevant standards (ISO C99,
POSIX:2001) and to provide access functions to the kernel's system
calls, and little more.

   There is no clear borderline between both areas.

   For example, Gnulib has a facility for generating the name of backup
files.  While this task is entirely at the application level -- no
standard specifies an API for it -- the nai"ve code has some
portability problems because on some platforms the length of file name
components is limited to 30 characters or so.  Gnulib handles that.

   Similarly, Gnulib has a facility for executing a command in a
subprocess.  It is at the same time a portability enhancement (it works
on GNU, Unix, and Windows, compared to the classical `fork'/`exec'
idiom which is not portable to Windows), as well as an application aid:
it takes care of redirecting stdin and/or stdout if desired, and emits
an error message if the subprocess failed.


File: gnulib.info,  Node: Target Platforms,  Next: Modules,  Prev: Portability and Application Code,  Up: Introduction

1.4 Target Platforms
====================

   Gnulib supports a number of platforms that we call the "reasonable
portability targets".  This class consists of widespread operating
systems, for three years after their last availability, or -- for
proprietary operating systems -- as long as the vendor provides
commercial support for it.  Already existing Gnulib code for older
operating systems is usually left in place for longer than these three
years.  So it comes that programs that use Gnulib run pretty well also
on these older operating systems.

   Some operating systems are not very widespread, but are Free
Software and are actively developed.  Such platforms are also supported
by Gnulib, if that OS's developers community keeps in touch with the
Gnulib developers, by providing bug reports, analyses, or patches.  For
such platforms, Gnulib supports only the versions of the last year or
the last few months, depending on the maturity of said OS project, the
number of its users, and how often these users upgrade.

   Niche operating systems are generally unsupported by Gnulib, unless
some of their developers or users contribute support to Gnulib.

   The degree of support Gnulib guarantees for a platform depends on the
amount of testing it gets from volunteers.  Platforms on which Gnulib
is frequently tested are the best supported.  Then come platforms with
occasional testing, then platforms which are rarely tested.  Usually,
we fix bugs when they are reported.  Except that some rarely tested
platforms are also low priority; bug fixes for these platforms can take
longer.

   As of 2011, the list of supported platforms is the following:

   * glibc systems.  With glibc 2.8 or newer, they are frequently
     tested.  With glibc 2.3 or newer, they are occasionally tested.

   * MacOS X.  In versions 10.5 and 10.6, it's frequently tested.  In
     version 10.4, it's rarely tested.

   * FreeBSD 6.0 or newer is occasionally tested.  FreeBSD 5.x is
     rarely tested.

   * NetBSD 5.0 or newer is occasionally tested.  NetBSD 3.0 or newer
     is rarely tested.

   * OpenBSD 4.0 or newer is occasionally tested.  OpenBSD 3.8 or newer
     is rarely tested.

   * AIX 6.1 or newer is occasionally tested.  AIX 5.1 or newer is
     rarely tested.

   * HP-UX 11.11 or newer is occasionally tested.  HP-UX 11.00 is
     rarely tested.  HP-UX 10.20 is rarely tested and low priority.

   * IRIX 6.5 is occasionally tested.  IRIX 5.3 is rarely tested and
     low priority.

   * OSF/1 5.1 is occasionally tested.  OSF/1 4.0 is rarely tested and
     low priority.

   * Solaris 8 and newer are occasionally tested.  Solaris 7 is rarely
     tested.  Solaris 2.6 and older are rarely tested and low priority.

   * Cygwin 1.7.x is frequently tested.  Cygwin 1.5.x is occasionally
     tested.

   * mingw is frequently tested.  But note that some modules are
     currently unsupported on mingw: `mgetgroups', `getugroups',
     `idcache', `userspec', `openpty', `login_tty', `forkpty',
     `pt_chown', `grantpt', `pty', `savewd', `mkancesdirs', `mkdir-p',
     `euidaccess', `faccessat'.  The versions of Windows that are
     supported are Windows XP and newer.

   * Native Windows, with MSVC as compiler, is rarely tested and low
     priority.

   * mingw in 64-bit mode is not tested and low priority so far.

   * Interix 6.1 is rarely tested, and requires the `suacomp' library
     (`http://sourceforge.net/projects/suacomp/') in version 0.6.8 or
     newer.  Interix 3.5 is not tested.

   * Haiku is rarely tested, BeOS is not tested and low priority.

   * uClibc on Linux is rarely tested.

   * QNX is not tested and low priority.

   Gnulib supports these operating systems only in an unvirtualized
environment.  When you run an OS inside a virtual machine, you have to
be aware that the virtual machine can bring in bugs of its own.  For
example, floating-point operations on Solaris can behave slightly
differently in QEMU than on real hardware.  And Haiku's `bash' program
misbehaves in VirtualBox 3, whereas it behaves fine in VirtualBox 4.

   Similarly, running native Windows binaries on GNU/Linux under WINE is
rarely tested and low priority: WINE has a set of behaviours and bugs
that is slightly different from native Windows.

   The following platforms are not supported by Gnulib.  The cost of
supporting them would exceed the benefit because they are rarely used,
or poorly documented, or have been supplanted by other platforms, or
diverge too much from POSIX, or some combination of these and other
factors.  Please don't bother sending us patches for them.

   * Windows 95/98/ME.

   * DJGPP and EMX (the 32-bit operating systems running in DOS).

   * MSDOS (the 16-bit operating system).

   * Windows Mobile, Symbian OS, iOS.


File: gnulib.info,  Node: Modules,  Next: Various Kinds of Modules,  Prev: Target Platforms,  Up: Introduction

1.5 Modules
===========

   Gnulib is divided into modules.  Every module implements a single
facility.  Modules can depend on other modules.

   A module consists of a number of files and a module description.  The
files are copied by `gnulib-tool' into the package that will use it,
usually verbatim, without changes.  Source code files (.h, .c files)
reside in the `lib/' subdirectory.  Autoconf macro files reside in the
`m4/' subdirectory.  Build scripts reside in the `build-aux/'
subdirectory.

   The module description contains the list of files -- `gnulib-tool'
copies these files.  It contains the module's dependencies --
`gnulib-tool' installs them as well.  It also contains the autoconf
macro invocation (usually a single line or nothing at all) --
`gnulib-tool' ensures this is invoked from the package's `configure.ac'
file.  And also a `Makefile.am' snippet -- `gnulib-tool' collects these
into a `Makefile.am' for the tailored Gnulib part.  The module
description and include file specification are for documentation
purposes; they are combined into `MODULES.html'.

   The module system serves two purposes:

  1. It ensures consistency of the used autoconf macros and
     `Makefile.am' rules with the source code.  For example, source
     code which uses the `getopt_long' function -- this is a common way
     to implement parsing of command line options in a way that
     complies with the GNU standards -- needs the source code
     (`lib/getopt.c' and others), the autoconf macro which detects
     whether the system's libc already has this function (in
     `m4/getopt.m4'), and a few `Makefile.am' lines that create the
     substitute `getopt.h' if not.  These three pieces belong together.
     They cannot be used without each other.  The module description and
     `gnulib-tool' ensure that they are copied altogether into the
     destination package.

  2. It allows for scalability.  It is well-known since the inception
     of the MODULA-2 language around 1978 that dissection into modules
     with dependencies allows for building large sets of code in a
     maintainable way.  The maintainability comes from the facts that:

        * Every module has a single purpose; you don't worry about
          other parts of the program while creating, reading or
          modifying the code of a module.

        * The code you have to read in order to understand a module is
          limited to the source of the module and the .h files of the
          modules listed as dependencies.  It is for this reason also
          that we recommend to put the comments describing the
          functions exported by a module into its .h file.

     In other words, the module is the elementary unit of code in
     Gnulib, comparable to a class in object-oriented languages like
     Java or C#.

   The module system is the basis of `gnulib-tool'.  When `gnulib-tool'
copies a part of Gnulib into a package, it first compiles a module
list, starting with the requested modules and adding all the
dependencies, and then collects the files, `configure.ac' snippets and
`Makefile.am' snippets.


File: gnulib.info,  Node: Various Kinds of Modules,  Next: Collaborative Development,  Prev: Modules,  Up: Introduction

1.6 Various Kinds of Modules
============================

   There are modules of various kinds in Gnulib.  For a complete list
of the modules, see in `MODULES.html'.

1.6.1 Support for ISO C or POSIX functions.
-------------------------------------------

   When a function is not implemented by a system, the Gnulib module
provides an implementation under the same name.  Examples are the
`snprintf' and `readlink' modules.

   Similarly, when a function is not correctly implemented by a system,
Gnulib provides a replacement.  For functions, we use the pattern

     #if !HAVE_WORKING_FOO
     # define foo rpl_foo
     #endif

and implement the `foo' function under the name `rpl_foo'.  This
renaming is needed to avoid conflicts at compile time (in case the
system header files declare `foo') and at link/run time (because the
code making use of `foo' could end up residing in a shared library, and
the executable program using this library could be defining `foo'
itself).

   For header files, such as `stdbool.h' or `stdint.h', we provide the
substitute only if the system doesn't provide a correct one.  The
template of this replacement is distributed in a slightly different
name, with `.in' inserted before the `.h' extension, so that on systems
which do provide a correct header file the system's one is used.

1.6.2 Enhancements of ISO C or POSIX functions
----------------------------------------------

   These are sometimes POSIX functions with GNU extensions also found in
glibc -- examples: `getopt', `fnmatch' -- and often new APIs -- for
example, for all functions that allocate memory in one way or the
other, we have variants which also include the error checking against
the out-of-memory condition.

1.6.3 Portable general use facilities
-------------------------------------

   Examples are a module for copying a file -- the portability problems
relate to the copying of the file's modification time, access rights,
and extended attributes -- or a module for extracting the tail
component of a file name -- here the portability to native Windows
requires a different API than the classical POSIX `basename' function.

1.6.4 Reusable application code
-------------------------------

   Examples are an error reporting function, a module that allows
output of numbers with K/M/G suffixes, or cryptographic facilities.

1.6.5 Object oriented classes
-----------------------------

   Examples are data structures like `list', or abstract output stream
classes that work around the fact that an application cannot implement
an stdio `FILE' with its logic.  Here, while staying in C, we use
implementation techniques like tables of function pointers, known from
the C++ language or from the Linux kernel.

1.6.6 Interfaces to external libraries
--------------------------------------

   Examples are the `iconv' module, which interfaces to the `iconv'
facility, regardless whether it is contained in libc or in an external
`libiconv'.  Or the `readline' module, which interfaces to the GNU
readline library.

1.6.7 Build / maintenance infrastructure
----------------------------------------

   An example is the `maintainer-makefile' module, which provides extra
Makefile tags for maintaining a package.

1.7 Collaborative Development
=============================

   Gnulib is maintained collaboratively.  The mailing list is
`<bug-gnulib at gnu dot org>'.  Be warned that some people on the list
may be very active at some times and unresponsive at other times.

   Every module has one or more maintainers.  While issues are discussed
collaboratively on the list, the maintainer of a module nevertheless has
a veto right regarding changes in his module.

   All patches should be posted the list, regardless whether they are
proposed patches or whether they are committed immediately by the
maintainer of the particular module.  The purpose is not only to inform
the other users of the module, but mainly to allow peer review.  It is
not uncommon that several people contribute comments or spot bugs after
a patch was proposed.

   Conversely, if you are using Gnulib, and a patch is posted that
affects one of the modules that your package uses, you have an interest
in proofreading the patch.


File: gnulib.info,  Node: Copyright,  Next: Steady Development,  Prev: Collaborative Development,  Up: Introduction

1.8 Copyright
=============

   Most modules are under the GPL.  Some, mostly modules which can
reasonably be used in libraries, are under LGPL.  The source files
always say "GPL", but the real license specification is in the module
description file.  If the module description file says "GPL", it means
"GPLv3+" (GPLv3 or newer, at the licensee's choice); if it says "LGPL",
it means "LGPLv3+" (LGPLv3 or newer, at the licensee's choice).

   More precisely, the license specification in the module description
file applies to the files in `lib/' and `build-aux/'.  Different
licenses apply to files in special directories:

`modules/'
     Module description files are under this copyright:

          Copyright (C) 200X-200Y Free Software Foundation, Inc.
          Copying and distribution of this file, with or without
          modification, in any medium, are permitted without royalty
          provided the copyright notice and this notice are preserved.

`m4/'
     Autoconf macro files are under this copyright:

          Copyright (C) 200X-200Y Free Software Foundation, Inc.
          This file is free software; the Free Software Foundation
          gives unlimited permission to copy and/or distribute it, with
          or without modifications, as long as this notice is preserved.

`tests/'
     If a license statement is not present in a test module, the test
     files are under GPL.  Even if the corresponding source module is
     under LGPL, this is not a problem, since compiled tests are not
     installed by "make install".

`doc/'
     Documentation files are under this copyright:

          Copyright (C) 2004-200Y Free Software Foundation, Inc.
          Permission is granted to copy, distribute and/or modify this
          document under the terms of the GNU Free Documentation
          License, Version 1.3 or any later version published by the
          Free Software Foundation; with no Invariant Sections, no
          Front-Cover Texts, and no Back-Cover Texts.  A copy of the
          license is included in the section entitled "GNU Free
          Documentation License".

   If you want to use some Gnulib modules under LGPL, you can do so by
passing the option `--lgpl' to `gnulib-tool'.  This will replace the
GPL header with an LGPL header while copying the source files to your
package.  Similarly, if you want some Gnulib modules under LGPLv2+
(Lesser GPL version 2.1 or newer), you can do so by passing the option
`--lgpl=2' to `gnulib-tool'.

   Keep in mind that when you submit patches to files in Gnulib, you
should license them under a compatible license.  This means that
sometimes the contribution will have to be LGPL, if the original file
is available under LGPL.  You can find out about it by looking for a
"License: LGPL" information in the corresponding module description.

1.9 Steady Development
======================

   Gnulib modules are continually adapted, to match new practices, to be
consistent with newly added modules, or simply as a response to build
failure reports.  Gnulib is available in two qualities:

   * There is the newest version of Gnulib from the Git repository.  The
     source tree can also be fetched from a read-only CVS that mirrors
     the Git repository.

   * We also make stable releases every two months, at
     `http://erislabs.net/ianb/projects/gnulib/'.

   If you are willing to report an occasional regression, we recommend
to use the newest version always, except in periods of major changes.
Most Gnulib users do this.  If you prefer stable releases, please use
the newest stable release.


File: gnulib.info,  Node: Openness,  Prev: Steady Development,  Up: Introduction

1.10 Openness
=============

   Gnulib is open in the sense that we gladly accept contributions if
they are generally useful, well engineered, and if the contributors
have signed the obligatory papers with the FSF.

   The module system is open in the sense that a package using Gnulib
can
  1. locally patch or override files in Gnulib,

  2. locally add modules that are treated like Gnulib modules by
     `gnulib-tool'.

   This is achieved by the `--local-dir' option of `gnulib-tool' (*note
Extending Gnulib::).


File: gnulib.info,  Node: Invoking gnulib-tool,  Next: Writing modules,  Prev: Introduction,  Up: Top

2 Invoking gnulib-tool
**********************

   The `gnulib-tool' command is the recommended way to import Gnulib
modules.  It is possible to borrow Gnulib modules in a package without
using `gnulib-tool', relying only on the meta-information stored in the
`modules/*' files, but with a growing number of modules this becomes
tedious.  `gnulib-tool' simplifies the management of source files,
`Makefile.am's and `configure.ac' in packages incorporating Gnulib
modules.

   `gnulib-tool' is not installed in a standard directory that is
contained in the `PATH' variable.  It needs to be run directly in the
directory that contains the Gnulib source code.  You can do this either
by specifying the absolute filename of `gnulib-tool', or you can also
use a symbolic link from a place inside your `PATH' to the
`gnulib-tool' file of your preferred and most up-to-date Gnulib
checkout, like this:
     $ ln -s $HOME/gnu/src/gnulib.git/gnulib-tool $HOME/bin/gnulib-tool

   Run `gnulib-tool --help' for information.  To get familiar with
`gnulib-tool' without affecting your sources, you can also try some
commands with the option `--dry-run'; then `gnulib-tool' will only
report which actions it would perform in a real run without changing
anything.

2.1 Finding modules
===================

   There are three ways of finding the names of Gnulib modules that you
can use in your package:

   * You have the complete module list, sorted according to categories,
     in `http://www.gnu.org/software/gnulib/MODULES.html'.

   * If you are looking for a particular POSIX header or function
     replacement, look in the chapters *note Header File Substitutes::
     and *note Function Substitutes::.  For headers and functions that
     are provided by Glibc but not standardized by POSIX, look in the
     chapters *note Glibc Header File Substitutes:: and *note Glibc
     Function Substitutes::.

   * If you have already found the source file in Gnulib and are
     looking for the module that contains this source file, you can use
     the command `gnulib-tool --find FILENAME'.


File: gnulib.info,  Node: Initial import,  Next: Modified imports,  Prev: Which modules?,  Up: Invoking gnulib-tool

2.2 Initial import
==================

   Gnulib assumes that your project uses Autoconf.  When using Gnulib,
you will need to have Autoconf and Automake among your build tools.
Note that while the use of Automake in your project's top level
directory is an easy way to fulfil the Makefile conventions of the GNU
coding standards, Gnulib does not require it.  But when you use Gnulib,
Automake will be used at least in a subdirectory of your project.

   Invoking `gnulib-tool --import' will copy source files, create a
`Makefile.am' to build them, generate a file `gnulib-comp.m4' with
Autoconf M4 macro declarations used by `configure.ac', and generate a
file `gnulib-cache.m4' containing the cached specification of how
Gnulib is used.

   Our example will be a library that uses Autoconf, Automake and
Libtool.  It calls `strdup', and you wish to use gnulib to make the
package portable to C89 and C99 (which don't have `strdup').

     You may need to add #include directives for the following .h files.
       #include <string.h>

     Don't forget to
       - add "lib/Makefile" to AC_CONFIG_FILES in ./configure.ac,
       - mention "lib" in SUBDIRS in Makefile.am,
       - mention "-I m4" in ACLOCAL_AMFLAGS in Makefile.am,
       - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC,
       - invoke gl_INIT in ./configure.ac.
     ~/src/libfoo$

   By default, the source code is copied into `lib/' and the M4 macros
in `m4/'.  You can override these paths by using
`--source-base=DIRECTORY' and `--m4-base=DIRECTORY'.  Some modules also
provide other files necessary for building.  These files are copied
into the directory specified by `AC_CONFIG_AUX_DIR' in `configure.ac'
or by the `--aux-dir=DIRECTORY' option.  If neither is specified, the
current directory is assumed.

   `gnulib-tool' can make symbolic links instead of copying the source
files.  The option to specify for this is `--symlink', or `-s' for
short.  This can be useful to save a few kilobytes of disk space.  But
it is likely to introduce bugs when `gnulib' is updated; it is more
reliable to use `gnulib-tool --update' (see below) to update to newer
versions of `gnulib'.  Furthermore it requires extra effort to create
self-contained tarballs, and it may disturb some mechanism the
maintainer applies to the sources.  For these reasons, this option is
generally discouraged.

   `gnulib-tool' will overwrite any pre-existing files, in particular
`Makefile.am'.  It is also possible to separate the generated
`Makefile.am' content (for building the gnulib library) into a separate
file, say `gnulib.mk', that can be included by your handwritten
`Makefile.am', but this is a more advanced use of `gnulib-tool'.

   Consequently, it is a good idea to choose directories that are not
already used by your projects, to separate gnulib imported files from
your own files.  This approach is also useful if you want to avoid
conflicts between other tools (e.g., `gettextize' that also copy M4
files into your package.  Simon Josefsson successfully uses a source
base of `gl/', and a M4 base of `gl/m4/', in several packages.

   After the `--import' option on the command line comes the list of
Gnulib modules that you want to incorporate in your package.  The names
of the modules coincide with the filenames in Gnulib's `modules/'
directory.

   Some Gnulib modules depend on other Gnulib modules.  `gnulib-tool'
will automatically add the needed modules as well; you need not list
them explicitly.  `gnulib-tool' will also memorize which dependent
modules it has added, so that when someday a dependency is dropped, the
implicitly added module is dropped as well (unless you have explicitly
requested that module).

   If you want to cut a dependency, i.e., not add a module although one
of your requested modules depends on it, you may use the option
`--avoid=MODULE' to do so.  Multiple uses of this option are possible.
Of course, you will then need to implement the same interface as the
removed module.

   A few manual steps are required to finish the initial import.
`gnulib-tool' printed a summary of these steps.

   First, you must ensure Autoconf can find the macro definitions in
`gnulib-comp.m4'.  Use the `ACLOCAL_AMFLAGS' specifier in your
top-level `Makefile.am' file, as in:

     ACLOCAL_AMFLAGS = -I m4

   You are now ready to call the M4 macros in `gnulib-comp.m4' from
`configure.ac'.  The macro `gl_EARLY' must be called as soon as
possible after verifying that the C compiler is working.  Typically,
this is immediately after `AC_PROG_CC', as in:

     ...
     AC_PROG_CC
     gl_EARLY
     ...

   If you are using `AC_PROG_CC_STDC', the macro `gl_EARLY' must be
called after it, like this:

     ...
     AC_PROG_CC
     AC_PROG_CC_STDC
     gl_EARLY
     ...

   The core part of the gnulib checks are done by the macro `gl_INIT'.
Place it further down in the file, typically where you normally check
for header files or functions.  It must come after other checks which
may affect the compiler invocation, such as `AC_MINIX'.  For example:

     ...
     # For gnulib.
     gl_INIT
     ...

   `gl_INIT' will in turn call the macros related with the gnulib
functions, be it specific gnulib macros, like `gl_FUNC_ALLOCA' or
autoconf or automake macros like `AC_FUNC_ALLOCA' or `AM_FUNC_GETLINE'.
So there is no need to call those macros yourself when you use the
corresponding gnulib modules.

   You must also make sure that the gnulib library is built.  Add the
`Makefile' in the gnulib source base directory to `AC_CONFIG_FILES', as
in:

     AC_CONFIG_FILES(... lib/Makefile ...)

   You must also make sure that `make' will recurse into the gnulib
directory.  To achieve this, add the gnulib source base directory to a
`SUBDIRS' Makefile.am statement, as in:

     SUBDIRS = lib

   or if you, more likely, already have a few entries in `SUBDIRS', you
can add something like:

     SUBDIRS += lib

   Finally, you have to add compiler and linker flags in the appropriate
source directories, so that you can make use of the gnulib library.
Since some modules (`getopt', for example) may copy files into the
build directory, `top_builddir/lib' is needed as well as
`top_srcdir/lib'.  For example:

     ...
     AM_CPPFLAGS = -I$(top_builddir)/lib -I$(top_srcdir)/lib
     ...
     LDADD = lib/libgnu.a
     ...

   Don't forget to `#include' the various header files.  In this
example, you would need to make sure that `#include <string.h>' is
evaluated when compiling all source code files, that want to make use
of `strdup'.

   In the usual case where Autoconf is creating a `config.h' file, you
should include `config.h' first, before any other include file.  That
way, for example, if `config.h' defines `restrict' to be the empty
string on a pre-C99 host, or a macro like `_FILE_OFFSET_BITS' that
affects the layout of data structures, the definition is consistent for
all include files.  Also, on some platforms macros like
`_FILE_OFFSET_BITS' and `_GNU_SOURCE' may be ineffective, or may have
only a limited effect, if defined after the first system header file is
included.

   Finally, note that you cannot use `AC_LIBOBJ' or `AC_REPLACE_FUNCS'
in your `configure.ac' and expect the resulting object files to be
automatically added to `lib/libgnu.a'.  This is because your
`AC_LIBOBJ' and `AC_REPLACE_FUNCS' invocations from `configure.ac'
augment a variable `@LIBOBJS@' (and/or `@LTLIBOBJS@' if using Libtool),
whereas `lib/libgnu.a' is built from the contents of a different
variable, usually `@gl_LIBOBJS@' (or `@gl_LTLIBOBJS@' if using Libtool).

2.3 Modified imports
====================

   You can at any moment decide to use Gnulib differently than the last
time.

   There are two ways to change how Gnulib is used.  Which one you'll
use, depends on where you keep track of options and module names that
you pass to `gnulib-tool'.

   * If you store the options and module names in a file under your own
     control, such as `autogen.sh', `bootstrap', `bootstrap.conf', or
     similar, simply invoke `gnulib-tool' again, with modified options
     and more or fewer module names.

   * `gnulib-tool' remembers which modules were used last time.  If you
     want to rely on `gnulib-tool''s own memory of the last used
     options and module names, you can use the commands `gnulib-tool
     --add-import' and `gnulib-tool --remove-import'.

     So, if you only want to use more Gnulib modules, simply invoke
     `gnulib-tool --add-import NEW-MODULES'.  The list of modules that
     you pass after `--add-import' is _added_ to the previous list of
     modules.

     Similarly, if you want to use fewer Gnulib modules, simply invoke
     `gnulib-tool --remove-import UNNEEDED-MODULES'.  The list of
     modules that you pass after `--remove-import' is _removed_ from
     the previous list of modules.  Note that if a module is then still
     needed as dependency of other modules, it will be used
     nevertheless.  If you want to _really_ not use a module any more,
     regardless of whether other modules may need it, you need to use
     the `--avoid' option.

     For other changes, such as different choices of `--lib',
     `--source-base' or `--aux-dir', the normal way is to modify
     manually the file `gnulib-cache.m4' in the M4 macros directory,
     then launch `gnulib-tool --add-import'.

     The only change for which this doesn't work is a change of the
     `--m4-base' directory.  Because, when you pass a different value of
     `--m4-base', `gnulib-tool' will not find the previous
     `gnulib-cache.m4' file any more.  A possible solution is to
     manually copy the `gnulib-cache.m4' into the new M4 macro
     directory.

     In the `gnulib-cache.m4' file, the macros have the following
     meaning:
    `gl_MODULES'
          The argument is a space separated list of the requested
          modules, not including dependencies.

    `gl_AVOID'
          The argument is a space separated list of modules that should
          not be used, even if they occur as dependencies.  Corresponds
          to the `--avoid' command line argument.

    `gl_SOURCE_BASE'
          The argument is the relative file name of the directory
          containing the gnulib source files (mostly *.c and *.h
          files).  Corresponds to the `--source-base' command line
          argument.

    `gl_M4_BASE'
          The argument is the relative file name of the directory
          containing the gnulib M4 macros (*.m4 files).  Corresponds to
          the `--m4-base' command line argument.

    `gl_TESTS_BASE'
          The argument is the relative file name of the directory
          containing the gnulib unit test files.  Corresponds to the
          `--tests-base' command line argument.

    `gl_LIB'
          The argument is the name of the library to be created.
          Corresponds to the `--lib' command line argument.

    `gl_LGPL'
          The presence of this macro without arguments corresponds to
          the `--lgpl' command line argument.  The presence of this
          macro with an argument (whose value must be 2 or 3)
          corresponds to the `--lgpl=ARG' command line argument.

    `gl_LIBTOOL'
          The presence of this macro corresponds to the `--libtool'
          command line argument and to the absence of the
          `--no-libtool' command line argument.  It takes no arguments.

    `gl_MACRO_PREFIX'
          The argument is the prefix to use for macros in the
          `gnulib-comp.m4' file.  Corresponds to the `--macro-prefix'
          command line argument.

2.4 Simple update
=================

   When you want to update to a more recent version of Gnulib, without
changing the list of modules or other parameters, a simple call does it:

     $ gnulib-tool --add-import

This will create, update or remove files, as needed.

   Note: From time to time, changes are made in Gnulib that are not
backward compatible.  When updating to a more recent Gnulib, you should
consult Gnulib's `NEWS' file to check whether the incompatible changes
affect your project.


File: gnulib.info,  Node: Source changes,  Next: gettextize and autopoint,  Prev: Simple update,  Up: Invoking gnulib-tool

2.5 Changing your sources for use with Gnulib
=============================================

   Gnulib contains some header file overrides.  This means that when
building on systems with deficient header files in `/usr/include/', it
may create files named `string.h', `stdlib.h', `stdint.h' or similar in
the build directory.  In the other source directories of your package
you will usually pass `-I' options to the compiler, so that these Gnulib
substitutes are visible and take precedence over the files in
`/usr/include/'.

   These Gnulib substitute header files rely on `<config.h>' being
already included.  Furthermore `<config.h>' must be the first include
in every compilation unit.  This means that to _all your source files_
and likely also to _all your tests source files_ you need to add an
`#include <config.h>' at the top.  Which source files are affected?
Exactly those whose compilation includes a `-I' option that refers to
the Gnulib library directory.

   This is annoying, but inevitable: On many systems, `<config.h>' is
used to set system dependent flags (such as `_GNU_SOURCE' on GNU
systems), and these flags have no effect after any system header file
has been included.


File: gnulib.info,  Node: gettextize and autopoint,  Next: Localization,  Prev: Source changes,  Up: Invoking gnulib-tool

2.6 Caveat: `gettextize' and `autopoint' users
==============================================

   The programs `gettextize' and `autopoint', part of GNU `gettext',
import or update the internationalization infrastructure.  Some of this
infrastructure, namely ca. 20 autoconf macro files and the
`config.rpath' file, is also contained in Gnulib and may be imported by
`gnulib-tool'.  The use of `gettextize' or `autopoint' will therefore
overwrite some of the files that `gnulib-tool' has imported, and vice
versa.

   Avoiding to use `gettextize' (manually, as package maintainer) or
`autopoint' (as part of a script like `autoreconf' or `autogen.sh') is
not the solution: These programs also import the infrastructure in the
`po/' and optionally in the `intl/' directory.

   The copies of the conflicting files in Gnulib are more up-to-date
than the copies brought in by `gettextize' and `autopoint'.  When a new
`gettext' release is made, the copies of the files in Gnulib will be
updated immediately.

   The solution is therefore:

  1. When you run `gettextize', always use the `gettextize' from the
     matching GNU gettext release.  For the most recent Gnulib
     checkout, this is the newest release found on
     `http://ftp.gnu.org/gnu/gettext/'.  For an older Gnulib snapshot,
     it is the release that was the most recent release at the time the
     Gnulib snapshot was taken.  Then, after `gettextize', invoke
     `gnulib-tool'.

  2. When a script of yours run `autopoint', invoke `gnulib-tool'
     afterwards.

  3. If you get an error message like `*** error: gettext
     infrastructure mismatch: using a Makefile.in.in from gettext
     version ...  but the autoconf macros are from gettext version ...',
     it means that a new GNU gettext release was made, and its autoconf
     macros were integrated into Gnulib and now mismatch the `po/'
     infrastructure.  In this case, fetch and install the new GNU
     gettext release and run `gettextize' followed by `gnulib-tool'.

  4. When you invoke `autoreconf' after `gnulib-tool', make sure to not
     invoke `autopoint' a second time, by setting the `AUTOPOINT'
     environment variable, like this:
          $ env AUTOPOINT=true autoreconf --install

2.7 Handling Gnulib's own message translations
==============================================

   Gnulib provides some functions that emit translatable messages using
GNU `gettext'.  The `gnulib' domain at the Translation Project
(http://translationproject.org/) collects translations of these
messages, which you should incorporate into your own programs.

   There are two basic ways to achieve this.  The first, and older,
method is to list all the source files you use from Gnulib in your own
`po/POTFILES.in' file.  This will cause all the relevant translatable
strings to be included in your POT file.  When you send this POT file
to the Translation Project, translators will normally fill in the
translations of the Gnulib strings from their "translation memory", and
send you back updated PO files.

   However, this process is error-prone: you might forget to list some
source files, or the translator might not be using a translation memory
and provide a different translation than another translator, or the
translation might not be kept in sync between Gnulib and your package.
It is also slow and causes substantial extra work, because a human
translator must be in the loop for each language and you will need to
incorporate their work on request.

   For these reasons, a new method was designed and is now recommended.
If you pass the `--po-base=DIRECTORY' and `--po-domain=DOMAIN' options
to `gnulib-tool', then `gnulib-tool' will create a separate directory
with its own `POTFILES.in', and fetch current translations directly
from the Translation Project (using `rsync' or `wget', whichever is
available).  The POT file in this directory will be called
`DOMAIN-gnulib.pot', depending on the DOMAIN you gave to the
`--po-domain' option (typically the same as the package name).  This
causes these translations to reside in a separate message domain, so
that they do not clash either with the translations for the main part
of your package nor with those of other packages on the system that use
possibly different versions of Gnulib.  When you use these options, the
functions in Gnulib are built in such a way that they will always use
this domain regardless of the default domain set by `textdomain'.

   In order to use this method, you must - in each program that might
use Gnulib code - add an extra line to the part of the program that
initializes locale-dependent behavior.  Where you would normally write
something like:

       setlocale (LC_ALL, "");
       bindtextdomain (PACKAGE, LOCALEDIR);
       textdomain (PACKAGE);

you should add an additional `bindtextdomain' call to inform gettext of
where the MO files for the extra message domain may be found:

       bindtextdomain (PACKAGE "-gnulib", LOCALEDIR);

   (This example assumes that the DOMAIN that you specified to
`gnulib-tool' is the same as the value of the `PACKAGE' preprocessor
macro.)

   Since you do not change the `textdomain' call, the default message
domain for your program remains the same and your own use of `gettext'
functions will not be affected.


File: gnulib.info,  Node: VCS Issues,  Next: Unit tests,  Prev: Localization,  Up: Invoking gnulib-tool

2.8 Issues with Version Control Systems
=======================================

   If a project stores its source files in a version control system
(VCS), such as CVS, Subversion, or Git, one needs to decide which files
to commit.

   In principle, all files created by `gnulib-tool', except
`gnulib-cache.m4', can be treated like generated source files, like for
example a `parser.c' file generated from `parser.y'.  Alternatively,
they can be considered source files and updated manually.

   Here are the three different approaches in common use.  Each has its
place, and you should use whichever best suits your particular project
and development methods.

  1. In projects which commit all source files, whether generated or
     not, into their VCS, the `gnulib-tool' generated files should all
     be committed.  In this case, you should pass the option
     `--no-vc-files' to `gnulib-tool', which avoids alteration of
     VCS-related files such as `.cvsignore'.

     Gnulib also contains files generated by `make' (and removed by
     `make clean'), using information determined by `configure'.  For a
     Gnulib source file of the form `lib/foo.in.h', the corresponding
     `lib/foo.h' is such a `make'-generated file.  These should _not_
     be checked into the VCS, but instead added to `.cvsignore' or
     equivalent.

  2. In projects which customarily omit from their VCS all files that
     are generated from other source files, none of these files and
     directories are added into the VCS.  As described in *note
     Modified imports::, there are two ways to keep track of options
     and module names that are passed to `gnulib-tool'.  The command
     for restoring the omitted files depends on it:

        * If they are stored in a file other than `gnulib-cache.m4',
          such as `autogen.sh', `bootstrap', `bootstrap.conf', or
          similar, the restoration command is the entire `gnulib-tool
          ... --import ...' invocation with all options and module
          names.

        * If the project relies on `gnulib-tool''s memory of the last
          used options and module names, then the file
          `gnulib-cache.m4' in the M4 macros directory must be added to
          the VCS, and the restoration command is:

               $ gnulib-tool --update

          The `--update' option operates much like the `--add-import'
          option, but it does not offer the possibility to change the
          way Gnulib is used.  Also it does not report in the
          ChangeLogs the files that it had to add because they were
          missing.


     Gnulib includes the file `build-aux/bootstrap' to aid a developer
     in using this setup.  Furthermore, in projects that use git for
     version control, it is possible to use a git submodule containing
     the precise commit of the gnulib repository, so that each developer
     running `bootstrap' will get the same version of all
     gnulib-provided files.  The location of the submodule can be
     chosen to fit the package's needs; here's how to initially create
     the submodule in the directory `.gnulib':

          $ dir=.gnulib
          $ git submodule add -- git://git.sv.gnu.org/gnulib.git $dir
          $ git config alias.syncsub "submodule foreach git pull origin master"

     Thereafter, `bootstrap' can run this command to update the
     submodule to the recorded checkout level:

          git submodule update --init $dir

     and a developer can use this sequence to update to a newer version
     of gnulib:

          $ git syncsub
          $ git add $dir
          $ ./bootstrap

  3. Some projects take a "middle road": they do commit Gnulib source
     files as in the first approach, but they do not commit other
     derived files, such as a `Makefile.in' generated by Automake.  This
     increases the size and complexity of the repository, but can help
     occasional contributors by not requiring them to have a full Gnulib
     checkout to do a build, and all developers by ensuring that all
     developers are working with the same version of Gnulib in the
     repository.  It also supports multiple Gnulib instances within a
     project.  It remains important not to commit the `make'-generated
     files, as described above.



File: gnulib.info,  Node: Unit tests,  Next: Conditional dependencies,  Prev: VCS Issues,  Up: Invoking gnulib-tool

2.9 Bundling the unit tests of the Gnulib modules
=================================================

   You can bundle the unit tests of the Gnulib modules together with
your package, through the `--with-tests' option.  Together with
`--with-tests', you also specify the directory for these tests through
the `--tests-base' option.  Of course, you need to add this directory
to the `SUBDIRS' variable in the `Makefile.am' of the parent directory.

   The advantage of having the unit tests bundled is that when your
program has a problem on a particular platform, running the unit tests
may help determine quickly if the problem is on Gnulib's side or on
your package's side.  Also, it helps verifying Gnulib's portability, of
course.

   The unit tests will be compiled and run when the user runs `make
check'.  When the user runs only `make', the unit tests will not be
compiled.

   In the `SUBDIRS' variable, it is useful to put the Gnulib tests
directory after the directory containing the other tests, not before:

     SUBDIRS = gnulib-lib src man tests gnulib-tests

This will ensure that on platforms where there are test failures in
either directory, users will see and report the failures from the tests
of your program.

   Note: In packages which use more than one invocation of `gnulib-tool'
in the scope of the same `configure.ac', you cannot use `--with-tests'.
You will have to use a separate `configure.ac' in this case.


File: gnulib.info,  Node: Conditional dependencies,  Prev: Unit tests,  Up: Invoking gnulib-tool

2.10 Avoiding unnecessary checks and compilations
=================================================

   In some cases, a module is needed by another module only on specific
platforms.  But when a module is present, its autoconf checks are always
executed, and its `Makefile.am' additions are always enabled.  So it
can happen that some autoconf checks are executed and some source files
are compiled, although no other module needs them on this particular
platform, just _in case_ some other module would need them.

   The option `--conditional-dependencies' enables an optimization of
configure checks and `Makefile.am' snippets that avoids this.  With
this option, whether a module is considered "present" is no longer
decided when `gnulib-tool' is invoked, but later, when `configure' is
run.  This applies to modules that were added as dependencies while
`gnulib-tool' was run; modules that were passed on the command line
explicitly are always "present".

   For example, the `timegm' module needs, on platforms where the
system's `timegm' function is missing or buggy, a replacement that is
based on a function `mktime_internal'.  The module `mktime-internal'
that provides this function provides it on all platforms.  So, by
default, the file `mktime-internal.c' will be compiled on all platforms
-- even on glibc and BSD systems which have a working `timegm'
function.  When the option `--conditional-dependencies' is given, on
the other hand, and if `mktime-internal' was not explicitly required on
the command line, the file `mktime-internal.c' will only be compiled on
the platforms where the `timegm' needs them.

   Conditional dependencies are specified in the module description by
putting the condition on the same line as the dependent module,
enclosed in brackets.  The condition is a boolean shell expression that
can assume that the `configure.ac' snippet from the module description
has already been executed.  In the example above, the dependency from
`timegm' to `mktime-internal' is written like this:

     Depends-on:
     ...
     mktime-internal [test $HAVE_TIMEGM = 0 || test $REPLACE_TIMEGM = 1]
     ...

   Note: The option `--conditional-dependencies' cannot be used together
with the option `--with-tests'.  It also cannot be used when a package
uses `gnulib-tool' for several subdirectories, with different values of
`--source-base', in the scope of a single `configure.ac' file.

3 Writing modules
*****************

   This chapter explains how to write modules of your own, either to
extend Gnulib for your own package (*note Extending Gnulib::), or for
inclusion in gnulib proper.

   The guidelines in this chapter do not necessarily need to be
followed for using `gnulib-tool'.  They merely represent a set of good
practices.  Following them will result in a good structure of your
modules and in consistency with gnulib.

3.1 Source code files
=====================

   Every API (C functions or variables) provided should be declared in
a header file (.h file) and implemented in one or more implementation
files (.c files).  The separation has the effect that users of your
module need to read only the contents of the .h file and the module
description in order to understand what the module is about and how to
use it - not the entire implementation.  Furthermore, users of your
module don't need to repeat the declarations of the functions in their
code, and are likely to receive notification through compiler errors if
you make incompatible changes to the API (like, adding a parameter or
changing the return type of a function).


File: gnulib.info,  Node: Header files,  Next: Implementation files,  Prev: Source code files,  Up: Writing modules

3.2 Header files
================

   The .h file should declare the C functions and variables that the
module provides.

   The .h file should be stand-alone.  That is, it does not require
other .h files to be included before.  Rather, it includes all
necessary .h files by itself.

   It is a tradition to use CPP tricks to avoid parsing the same header
file more than once, which might cause warnings.  The trick is to wrap
the content of the header file (say, `foo.h') in a block, as in:

     #ifndef FOO_H
     # define FOO_H
     ...
     body of header file goes here
     ...
     #endif /* FOO_H */

   Whether to use `FOO_H' or `_FOO_H' is a matter of taste and style.
The C89 and C99 standards reserve all identifiers that begin with an
underscore and either an uppercase letter or another underscore, for
any use.  Thus, in theory, an application might not safely assume that
`_FOO_H' has not already been defined by a library.  On the other hand,
using `FOO_H' will likely lead the higher risk of collisions with other
symbols (e.g., `KEY_H', `XK_H', `BPF_H', which are CPP macro constants,
or `COFF_LONG_H', which is a CPP macro function).  Your preference may
depend on whether you consider the header file under discussion as part
of the application (which has its own namespace for CPP symbols) or a
supporting library (that shouldn't interfere with the application's CPP
symbol namespace).

   Adapting C header files for use in C++ applications can use another
CPP trick, as in:

     # ifdef __cplusplus
     extern "C"
     {
     # endif
     ...
     body of header file goes here
     ...
     # ifdef __cplusplus
     }
     # endif

   The idea here is that `__cplusplus' is defined only by C++
implementations, which will wrap the header file in an `extern "C"'
block.  Again, whether to use this trick is a matter of taste and
style.  While the above can be seen as harmless, it could be argued
that the header file is written in C, and any C++ application using it
should explicitly use the `extern "C"' block itself.  Your preference
might depend on whether you consider the API exported by your header
file as something available for C programs only, or for C and C++
programs alike.

   Note that putting a `#include' in an `extern "C" { ... }' block
yields a syntax error in C++ mode on some platforms (e.g., glibc
systems with g++ v3.3 to v4.2, AIX, OSF/1, IRIX).  For this reason, it
is recommended to place the `#include' before the `extern "C"' block.


File: gnulib.info,  Node: Implementation files,  Next: Specification,  Prev: Header files,  Up: Writing modules

3.3 Implementation files
========================

   The .c file or files implement the functions and variables declared
in the .h file.

Include ordering
----------------

   Every implementation file must start with `#include <config.h>'.
This is necessary for activating the preprocessor macros that are
defined on behalf of the Autoconf macros.  Some of these preprocessor
macros, such as `_GNU_SOURCE', would have no effect if defined after a
system header file has already been included.

   Then comes the `#include "..."' specifying the header file that is
being implemented.  Putting this right after `#include <config.h>' has
the effect that it verifies that the header file is self-contained.

   Then come the system and application headers. It is customary to put
all the system headers before all application headers, so as to
minimize the risk that a preprocessor macro defined in an application
header confuses the system headers on some platforms.

   In summary:

   * First comes #include <config.h>.

   * Second comes the #include "..." specifying the module being
     implemented.

   * Then come all the #include <...> of system or system-replacement
     headers, in arbitrary order.

   * Then come all the #include "..." of gnulib and application
     headers, in arbitrary order.


File: gnulib.info,  Node: Specification,  Next: Module description,  Prev: Implementation files,  Up: Writing modules

3.4 Specification
=================

   The specification of a function should answer at least the following
questions:
   * What is the purpose of the function?

   * What are the arguments?

   * What is the return value?

   * What happens in case of failure? (Exit? A specific return value?
     Errno set?)

   * Memory allocation policy: If pointers to memory are returned, are
     they freshly allocated and supposed to be freed by the caller?

   Where to put the specification describing exported functions? Three
practices are used in gnulib:

   * The specification can be as comments in the header file, just
     above the function declaration.

   * The specification can be as comments in the implementation file,
     just above the function definition.

   * The specification can be in texinfo format, so that it gets
     included in the gnulib manual.

   In any case, the specification should appear in just one place,
unless you can ensure that the multiple copies will always remain
identical.

   The advantage of putting it in the header file is that the user only
has to read the include file normally never needs to peek into the
implementation file(s).

   The advantage of putting it in the implementation file is that when
reviewing or changing the implementation, you have both elements side
by side.

   The advantage of texinfo formatted documentation is that it is easily
published in HTML or Info format.

   Currently (as of 2010), half of gnulib uses the first practice,
nearly half of gnulib uses the second practice, and a small minority
uses the texinfo practice.


File: gnulib.info,  Node: Module description,  Next: Autoconf macros,  Prev: Specification,  Up: Writing modules

3.5 Module description
======================

   For the module description, you can start from an existing module's
description, or from a blank one: `module/TEMPLATE' for a normal module,
or `module/TEMPLATE-TESTS' for a unit test module.  Some more fields
are possible but rarely used.  Use `module/TEMPLATE-EXTENDED' if you
want to use one of them.

   Module descriptions have the following fields.  Absent fields are
equivalent to fields with empty contents.

Description
     This field should contain a concise description of the module's
     functionality.  One sentence is enough.  For example, if it
     defines a single function `frob', the description can be `frob()
     function: frobnication.' Gnulib's documentation generator will
     automatically convert the first part to a hyperlink when it has
     this form.

Status
     This field is either empty/absent, or contains the word
     `obsolete'.  In the latter case, `gnulib-tool' will, unless the
     option `--with-obsolete' is given, omit it when it used as a
     dependency.  It is good practice to also notify the user about an
     obsolete module.  This is done by putting into the `Notice'
     section (see below) text like `This module is obsolete.'

Notice
     This field contains text that `gnulib-tool' will show to the user
     when the module is used.  This can be a status indicator like
     `This module is obsolete.' or additional advice.  Do not abuse this
     field.

Applicability
     This field is either empty/absent, or contains the word `all'.  It
     describes to which `Makefile.am' the module is applied.  By
     default, a normal module is applied to `SOURCE_BASE/Makefile.am'
     (normally `lib/Makefile.am'), whereas a module ending in `-tests'
     is applied to `TESTS_BASE/Makefile.am' (normally
     `tests/Makefile.am').  If this field is `all', it is applied to
     both `Makefile.am's.  This is useful for modules which provide
     Makefile.am macros rather than compiled source code.

Files
     This field contains a newline separated list of the files that are
     part of the module.  `gnulib-tool' copies these files into the
     package that uses the module.

     This list is typically ordered by importance: First comes the
     header file, then the implementation files, then other files.

     It is possible to have the same file mentioned in multiple
     modules.  That is, if the maintainers of that module agree on the
     purpose and future of said file.

Depends-on
     This field contains a newline separated list of the modules that
     are required for the proper working of this module.  `gnulib-tool'
     includes each required module automatically, unless it is
     specified with option `--avoid' or it is marked as obsolete and
     the option `--with-obsolete' is not given.

     A test modules `foo-tests' implicitly depends on the corresponding
     non-test module `foo'.  `foo' implicitly depends on `foo-tests' if
     the latter exists and if the option `--with-tests' has been given.

     Tests modules can depend on non-tests modules.  Non-tests modules
     should not depend on tests modules. (Recall that tests modules are
     built in a separate directory.)

     Each listed required module may be declared a conditional
     dependency.  This is indicated by placing the condition for the
     dependency on the same line, enclosed in brackets, after the name
     of the required module.  The condition is a shell expression that
     is run after the module's `configure.ac' statements.  For example:
          strtoull   [test $ac_cv_func_strtoumax = no]

     Lines starting with `#' are recognized as comments and are ignored.

configure.ac-early
     This field contains `configure.ac' stuff (Autoconf macro
     invocations and shell statements) that are logically placed early
     in the `configure.ac' file: right after the `AC_PROG_CC'
     invocation.  This section is adequate for statements that modify
     `CPPFLAGS', as these can affect the results of other Autoconf
     macros.

configure.ac
     This field contains `configure.ac' stuff (Autoconf macro
     invocations and shell statements).

     It is forbidden to add items to the `CPPFLAGS' variable here,
     other than temporarily, as these could affect the results of other
     Autoconf macros.

     We avoid adding items to the `LIBS' variable, other than
     temporarily.  Instead, the module can export an
     Autoconf-substituted variable that contains link options.  The
     user of the module can then decide to which executables to apply
     which link options.  Recall that a package can build executables of
     different kinds and purposes; having all executables link against
     all libraries is inappropriate.

     If the statements in this section grow larger than a couple of
     lines, we recommend moving them to a `.m4' file of their own.

Makefile.am
     This field contains `Makefile.am' statements.  Variables like
     `lib_SOURCES' are transformed to match the name of the library
     being built in that directory.  For example, `lib_SOURCES' may
     become `libgnu_a_SOURCES' (for a plain library) or
     `libgnu_la_SOURCES' (for a libtool library).  Therefore, the
     normal way of having an implementation file `lib/foo.c' compiled
     unconditionally is to write
          lib_SOURCES += foo.c

Include
     This field contains the preprocessor statements that users of the
     module need to add to their source code files.  Typically it's a
     single include statement.  A shorthand is allowed: You don't need
     to write the word "#include", just the name of the include file in
     the way it will appear in an include statement.  Example:
          "foo.h"

Link
     This field contains the set of libraries that are needed when
     linking libraries or executables that use this module.  Often this
     will be written as a reference to a Makefile variable.  Please
     write them one per line, so that `gnulib-tool' can remove
     duplicates when presenting a summary to the user.  Example:
          $(POW_LIBM)
          $(LTLIBICONV) when linking with libtool, $(LIBICONV) otherwise

License
     This field specifies the license that governs the source code
     parts of this module.  See *note Copyright:: for details.

Maintainer
     This field specifies the persons who have a definitive say about
     proposed changes to this module.  You don't need to mention email
     addresses here: they can be inferred from the `ChangeLog' file.

     Please put at least one person here.  We don't like unmaintained
     modules.


File: gnulib.info,  Node: Autoconf macros,  Next: Unit test modules,  Prev: Module description,  Up: Writing modules

3.6 Autoconf macros
===================

   For a module `foo', an Autoconf macro file `m4/foo.m4' is typically
created when the Autoconf macro invocations for the module are longer
than one or two lines.

   The name of the main entry point into this Autoconf macro file is
typically `gl_FOO'.  For modules outside Gnulib that are not likely to
be moved into Gnulib, please use a prefix specific to your package:
`gt_' for GNU gettext, `cu_' for GNU coreutils, etc.

   For modules that define a function `foo', the entry point is called
`gl_FUNC_FOO' instead of `gl_FOO'.  For modules that provide a header
file with multiple functions, say `foo.h', the entry point is called
`gl_FOO_H' or `gl_HEADER_FOO_H'.  This convention is useful because
sometimes a header and a function name coincide (for example, `fcntl'
and `fcntl.h').

   For modules that provide a replacement, it is useful to split the
Autoconf macro into two macro definitions: one that detects whether the
replacement is needed and requests the replacement using `AC_LIBOBJ'
(this is the entry point, say `gl_FUNC_FOO'), and one that arranges for
the macros needed by the replacement code `lib/foo.c' (typically called
`gl_PREREQ_FOO').  The reason of this separation is
  1. to make it easy to update the Autoconf macros when you have
     modified the source code file: after changing `lib/foo.c', all you
     have to review is the `Depends-on' section of the module
     description and the `gl_PREREQ_FOO' macro in the Autoconf macro
     file.

  2. The Autoconf macros are often large enough that splitting them
     eases maintenance.


File: gnulib.info,  Node: Unit test modules,  Next: Incompatible changes,  Prev: Autoconf macros,  Up: Writing modules

3.7 Unit test modules
=====================

   A unit test that is a simple C program usually has a module
description as simple as this:

     Files:
     tests/test-foo.c
     tests/macros.h

     Depends-on:

     configure.ac:

     Makefile.am:
     TESTS += test-foo
     check_PROGRAMS += test-foo

   The test program `tests/test-foo.c' often has the following
structure:

   * First comes the obligatory `#include <config.h>'.

   * Second comes the include of the header file that declares the API
     being tested.  Including it here verifies that said header file is
     self-contained.

   * Then come other includes.  In particular, the file `macros.h' is
     often used here.  It contains a convenient `ASSERT' macro.

   The body of the test, then, contains many `ASSERT' invocations.  When
a test fails, the `ASSERT' macro prints the line number of the failing
statement, thus giving you, the developer, an idea of which part of the
test failed, even when you don't have access to the machine where the
test failed and the reporting user cannot run a debugger.

   Sometimes it is convenient to write part of the test as a shell
script.  (For example, in areas related to process control or
interprocess communication, or when different locales should be tried.)
In these cases, the typical module description is like this:

     Files:
     tests/test-foo.sh
     tests/test-foo.c
     tests/macros.h

     Depends-on:

     configure.ac:

     Makefile.am:
     TESTS += test-foo.sh
     TESTS_ENVIRONMENT += FOO_BAR='@FOO_BAR@'
     check_PROGRAMS += test-foo

   Here, the `TESTS_ENVIRONMENT' variable can be used to pass values
determined by `configure' or by the `Makefile' to the shell script, as
environment variables.  The values of `EXEEXT' and of `srcdir', from
Autoconf and Automake, are already provided as environment variables,
through an initial value of `TESTS_ENVIRONMENT' that `gnulib-tool' puts
in place.

   Regardless of the specific form of the unit test, the following
guidelines should be respected:

   * A test indicates success by exiting with exit code 0.  It should
     normally not produce output in this case.  (Output to temporary
     files that are cleaned up at the end of the test are possible, of
     course.)

   * A test indicates failure by exiting with an exit code different
     from 0 and 77, typically 1.  It is useful to print a message about
     the failure in this case.  The `ASSERT' macro already does so.

   * A test indicates "skip", that is, that most of its interesting
     functionality could not be performed, through a return code of 77.
     A test should also print a message to stdout or stderr about the
     reason for skipping.  For example:
            fputs ("Skipping test: multithreading not enabled\n", stderr);
            return 77;
     Such a message helps detecting bugs in the autoconf macros: A
     simple message `SKIP: test-foo' does not sufficiently catch the
     attention of the user.


File: gnulib.info,  Node: Incompatible changes,  Prev: Unit test modules,  Up: Writing modules

3.8 Incompatible changes
========================

   Incompatible changes to Gnulib modules should be mentioned in
Gnulib's `NEWS' file.  Incompatible changes here mean that existing
source code may not compile or work any more.

   We don't mean changes in the binary interface (ABI), since
  1. Gnulib code is used in source-code form.

  2. The user who distributes libraries that contain Gnulib code is
     supposed to bump the version number in the way described in the
     Libtool documentation before every release.

4 Extending Gnulib
******************

   Gnulib modules are intended to be suitable for widespread use.  Most
problems with Gnulib can and should be fixed in a generic way, so that
all of Gnulib's users can benefit from the change.  But occasionally a
problem arises that is difficult or undesirable to fix generically, or
a project that uses Gnulib may need to work around an issue before the
Gnulib maintainers commit a final fix.  Maintainers may also want to
add their own pools of modules to projects as Gnulib "staging areas."

   The obvious way to make local changes to Gnulib modules is to use
`gnulib-tool' to check out pristine modules, then to modify the results
in-place.  This works well enough for short-lived experiments.  It is
harder to keep modified versions of Gnulib modules for a long time,
even though Git (or another distributed version control systems) can
help out a lot with this during the development process.

   Git, however, doesn't address the distribution issue.  When a package
"foobar" needs a modified version of, say, `stdint.in.h', it either has
to put a comment into `foobar/autogen.sh' saying "Attention! This
doesn't work with a pristine Gnulib, you need this and that patch after
checking out Gnulib," or it has to use the `--avoid=stdint' option and
provide the modified `stdint' module in a different directory.

   The `--local-dir' option to `gnulib-tool' solves this problem.  It
allows the package to override or augment Gnulib.  This means:

   * You can store files that are to override Gnulib files or modules.

   * You can store context diffs to be applied to Gnulib files.

   * You can add modules of your own, that are not (yet) in Gnulib.

   * You can also add unstructured amounts of code to the library, by
     grouping the non-Gnulib files of the library in a single
     kitchen-sink "module."  (This kind of kitchen-sink module is not
     needed when you use the `gnulib-tool' option `--makefile-name'.)

   In a release tarball, you can distribute the contents of this
`--local-dir' directory that will be combinable with newer versions of
Gnulib, barring incompatible changes to Gnulib.

   If the `--local-dir=DIRECTORY' option is specified, then
`gnulib-tool' looks in `DIRECTORY' whenever it reads a file from the
Gnulib directory.  Suppose `gnulib-tool' is looking for FILE.  Then:

   * If `DIRECTORY/FILE' exists, then `gnulib-tool' uses it instead of
     the file included in Gnulib.

   * Otherwise, if `DIRECTORY/FILE.diff' exists, then `gnulib-tool'
     uses the file from Gnulib after applying the diff using the
     `patch' program.

   * Otherwise, `gnulib-tool' uses the file included in Gnulib.

   Please make wise use of this option.  It also allows you to easily
hold back modifications you make to Gnulib macros in cases it may be
better to share them.

File: gnulib.info,  Node: Out of memory handling,  Next: Obsolete modules,  Up: Miscellaneous Notes

5.1 Out of memory handling
==========================

   The gnulib API does not have a standard error code for the out of
memory error condition.  Instead of adding a non-standard error code,
gnulib has chosen to adopt a different strategy.  Out of memory handling
happens in rare situations, but performing the out of memory error
handling after almost all API function invocations pollute your source
code and might make it harder to spot more serious problems.  The
strategy chosen improves code readability and robustness.

   For most applications, aborting the application with an error message
when the out of memory situation occurs is the best that can be wished
for.  This is how the library behaves by default (using the
`xalloc-die' module).

   However, we realize that some applications may not want to abort
execution in any situation.  Gnulib supports a hook to let the
application regain control and perform its own cleanups when an out of
memory situation has occurred.  The application can define a function
(having a `void' prototype, i.e., no return value and no parameters)
and set the library variable `xalloc_die' to that function.  The
variable should be declared as follows.

     extern void (*xalloc_die) (void);

   Gnulib will invoke this function if an out of memory error occurs.
Note that the function should not return.  Of course, care must be
taken to not allocate more memory, as that will likely also fail.


File: gnulib.info,  Node: Obsolete modules,  Next: Extra tests modules,  Prev: Out of memory handling,  Up: Miscellaneous Notes

5.2 Obsolete modules
====================

   Modules can be marked obsolete.  This means that the problems they
fix don't occur any more on the platforms that are reasonable porting
targets now.  `gnulib-tool' warns when obsolete modules are mentioned
on the command line, and by default ignores dependencies from modules
to obsolete modules.  When you pass the option `--with-obsolete' to
`gnulib-tool', dependencies to obsolete modules will be included,
however, unless blocked through an `--avoid' option.  This option is
useful if your package should be portable even to very old platforms.

   In order to mark a module obsolete, you need to add this to the
module description:

     Status:
     obsolete

     Notice:
     This module is obsolete.


File: gnulib.info,  Node: Extra tests modules,  Next: A C++ namespace for gnulib,  Prev: Obsolete modules,  Up: Miscellaneous Notes

5.3 Extra tests modules
=======================

   Test modules can be marked with some special status attributes.
When a test module has such an attribute, `gnulib-tool --import' will
not include it by default.

   The supported status attributes are:

`c++-test'
     Indicates that the test is testing C++ interoperability.  Such a
     test is useful in a C++ or mixed C/C++ package, but is useless in
     a C package.

`longrunning-test'
     Indicates that the test takes a long time to compile or execute
     (more than five minutes or so).  Such a test is better avoided in
     a release that is made for the general public.

`privileged-test'
     Indicates that the test will request special privileges, for
     example, ask for the superuser password.  Such a test may hang
     when run non-interactively and is therefore better avoided in a
     release that is made for the general public.

`unportable-test'
     Indicates that the test is known to fail on some systems, and that
     there is no workaround about it.  Such a test is better avoided in
     a release that is made for the general public.

   `gnulib-tool --import --with-tests' will not include tests marked
with these attributes by default.  When `gnulib-tool' is invoked with
one of the options `--with-c++-tests', `--with-longrunning-tests',
`--with-privileged-tests', `--with-unportable-tests', it will include
tests despite the corresponding special status attribute.  When
`gnulib-tool' receives the option `--with-all-tests', it will include
all tests regardless of their status attributes.

   `gnulib-tool --create-testdir --with-tests' and `gnulib-tool
--create-megatestdir --with-tests' by default include all tests of
modules specified on the command line, regardless of their status
attributes.  Tests of modules occurring as dependencies are not included
by default if they have one of these status attributes.  The options
`--with-c++-tests', `--with-longrunning-tests',
`--with-privileged-tests', `--with-unportable-tests' are recognized
here as well.  Additionally, `gnulib-tool' also understands the options
`--without-c++-tests', `--without-longrunning-tests',
`--without-privileged-tests', `--without-unportable-tests'.

   In order to mark a module with a status attribute, you need to add it
to the module description, like this:

     Status:
     longrunning-test

   If only a part of a test deserves a particular status attribute, you
can split the module into a primary and a secondary test module, say
`foo-tests' and `foo-extra-tests'.  Then add a dependency from
`foo-tests' to `foo-extra-tests', and mark the `foo-extra-tests' with
the particular status attribute.

5.4 A C++ namespace for gnulib
==============================

   The function definitions provided by Gnulib (`.c' code) are meant to
be compiled by a C compiler.  The header files (`.h' files), on the
other hand, can be used in either C or C++.

   By default, when used in a C++ compilation unit, the `.h' files
declare the same symbols and overrides as in C mode, except that
functions defined by Gnulib or by the system are declared as `extern
"C"'.

   It is also possible to indicate to Gnulib to provide many of its
symbols in a dedicated C++ namespace.  If you define the macro
`GNULIB_NAMESPACE' to an identifier, many functions will be defined in
the namespace specified by the identifier instead of the global
namespace.  For example, after you have defined
     #define GNULIB_NAMESPACE gnulib
   at the beginning of a compilation unit, Gnulib's `<fcntl.h>' header
file will make available the `open' function as `gnulib::open'.  The
symbol `open' will still refer to the system's `open' function, with
its platform specific bugs and limitations.

   The symbols provided in the Gnulib namespace are those for which the
corresponding header file contains a `_GL_CXXALIAS_RPL' or
`_GL_CXXALIAS_SYS' macro invocation.

   The benefits of this namespace mode are:
   * Gnulib defines fewer symbols as preprocessor macros.  For example,
     on a platform where `open' has to be overridden, Gnulib normally
     does `#define open rpl_open'.  If your package has a class with a
     member `open', for example a class `foo' with a method `foo::open',
     then if you define this member in a compilation unit that includes
     `<fcntl.h>' and use it in a compilation unit that does not include
     `<fcntl.h>', or vice versa, you will get a link error.  Worse: You
     will not notice this problem on the platform where the system's
     `open' function works fine.  This problem goes away in namespace
     mode.

   * It provides a safety check whether the set of modules your package
     requests from Gnulib is sufficient.  For example, if you use the
     function `gnulib::open' in your code, and you forgot to request
     the module `open' from Gnulib, you will get a compilation error
     (regardless of the platform).

   The drawback of this namespace mode is that the system provided
symbols in the global namespace are still present, even when they
contain bugs that Gnulib fixes.  For example, if you call `open (...)'
in your code, it will invoke the possibly buggy system function, even
if you have requested the module `open' from gnulib-tool.

   You can turn on the namespace mode in some compilation units and
keep it turned off in others.  This can be useful if your package
consists of an application layer that does not need to invoke POSIX
functions and an operating system interface layer that contains all the
OS function calls.  In such a situation, you will want to turn on the
namespace mode for the application layer -- to avoid many preprocessor
macro definitions -- and turn it off for the OS interface layer -- to
avoid the drawback of the namespace mode, mentioned above.

5.5 Library version handling
============================

   The module `check-version' can be useful when your gnulib
application is a system library.  You will typically wrap the call to
the `check_version' function through a library API, your library header
file may contain:

     #define STRINGPREP_VERSION "0.5.18"
     ...
       extern const char *stringprep_check_version (const char *req_version);

   To avoid ELF symbol collisions with other libraries that use the
`check-version' module, add to `config.h' through a AC_DEFINE something
like:

     AC_DEFINE(check_version, stringprep_check_version,
               [Rename check_version.])

   The `stringprep_check_version' function will thus be implemented by
the `check_version' module.

   There are two uses of the interface.  The first is a way to provide
for applications to find out the version number of the library it uses.
The application may contain diagnostic code such as:

       printf ("Stringprep version: header %s library %s",
               STRINGPREP_VERSION,
               stringprep_check_version (NULL));

   Separating the library and header file version can be useful when
searching for version mismatch related problems.

   The second uses is as a rudimentary test of proper library version,
by making sure the application get a library version that is the same,
or newer, than the header file used when building the application.  This
doesn't catch all problems, libraries may change backwards incompatibly
in later versions, but enable applications to require a certain minimum
version before it may proceed.

   Typical uses look like:

            /* Check version of libgcrypt. */
            if (!gcry_check_version (GCRYPT_VERSION))
              die ("version mismatch\n");


File: gnulib.info,  Node: Windows sockets,  Next: Libtool and Windows,  Prev: Library version handling,  Up: Miscellaneous Notes

5.6 Windows sockets
===================

   There are several issues when building applications that should work
under Windows.  The most problematic part is for applications that use
sockets.

   Hopefully, we can add helpful notes to this section that will help
you port your application to Windows using gnulib.

5.6.1 Getaddrinfo and WINVER
----------------------------

   This was written for the getaddrinfo module, but may be applicable to
other functions too.

   The getaddrinfo function exists in ws2tcpip.h and -lws2_32 on Windows
XP.  The function declaration is present if `WINVER >= 0x0501'.
Windows 2000 does not have getaddrinfo in its `WS2_32.DLL'.

   Thus, if you want to assume Windows XP or later, you can add
AC_DEFINE(WINVER, 0x0501) to avoid compiling the (partial) getaddrinfo
implementation.

   If you want to support Windows 2000, don't do anything.  The
replacement function will open `WS2_32.DLL' during run-time to see if
there is a getaddrinfo function available, and use it when available.

5.7 Libtool and Windows
=======================

   If you want it to be possible to cross-compile your program to MinGW
and you use Libtool, you need to put:

     AC_LIBTOOL_WIN32_DLL

   in your `configure.ac'.  This sets the correct names for the
`OBJDUMP', `DLLTOOL', and `AS' tools for the build.

   If you are building a library, you will also need to pass
`-no-undefined' to make sure Libtool produces a DLL for your library.
From a `Makefile.am':

     libgsasl_la_LDFLAGS += -no-undefined

5.8 License Texinfo sources
===========================

   Gnulib provides copies of the GNU GPL, GNU LGPL, and GNU FDL licenses
in Texinfo form.  (The master location is
`http://www.gnu.org/licenses/').  These Texinfo documents do not have
any node names and structures built into them; for your manual, you
should `@include' them in an appropriate `@node'.

   The conventional name for the GPL node is `Copying' and for the FDL
`GNU Free Documentation License'.  The LGPL doesn't seem to have a
conventional node name.

   Of course the license texts themselves should not be changed at all.

5.9 Build robot for gnulib
==========================

   To simplify testing on a wide set of platforms, gnulib is built on
many platforms every day and the results are uploaded to:

   `http://autobuild.josefsson.org/gnulib/'

   If you wish to help the gnulib development effort with build logs for
your favorite platform, you may perform these steps:

  1. Create gnulib directory

     On a machine with recent automake, autoconf, m4 installed and with
     a gnulib git or cvs checkout (typically a Linux machine), use

          gnulib-tool --create-megatestdir --with-tests --dir=...

     Note: The created directory uses ca. 512 MB on disk.

  2. Transfer gnulib directory

     Transfer this directory to a build machine (HP-UX, Cygwin, or
     whatever).  Often it is easier to transfer one file, and this can
     be achieved by running, inside the directory the following
     commands:

          ./configure
          make dist

     And then transferring the `dummy-0.tar.gz' file.

  3. Build modules

     On the build machine, run ./do-autobuild (or "nohup
     ./do-autobuild").  It creates a directory `logs/' with a log file
     for each module.

  4. Submit build logs

     Submit each log file to Simon's site, either through a

          mail `echo gnulib__at__autobuild.josefsson.org | sed -e s/__at__/@/`

     or through netcat

          autobuild-submit logs/*

6 Building the ISO C and POSIX Substitutes
******************************************

   This section shows a radically different way to use Gnulib.

   You can extract the ISO C / POSIX substitutes part of gnulib by
running the command
     gnulib-tool --create-testdir --source-base=lib \
                 --dir=/tmp/posixlib `posix-modules`

The command `posix-modules' is found in the same directory as
`gnulib-tool'.

   The resulting directory can be built on a particular platform,
independently of the program being ported.  Then you can configure and
build any program, by setting `CPPFLAGS' and `LDFLAGS' at configure
time accordingly: set `CPPFLAGS="-I.../posixlib/lib"', plus any
essential type definitions and flags that you find in
`.../posixlib/config.h', and set `LDFLAGS=".../posixlib/lib/libgnu.a"'.

   This way of using Gnulib is useful when you don't want to modify the
program's source code, or when the program uses a mix between C and C++
sources (requiring separate builds of the `posixlib' for the C compiler
and for the C++ compiler).

7 ISO C and POSIX Header File Substitutes
*****************************************

   This chapter describes which header files specified by ISO C or
POSIX are substituted by Gnulib, which portability pitfalls are fixed
by Gnulib, and which (known) portability problems are not worked around
by Gnulib.

   The notation "Gnulib module: --" means that Gnulib does not provide a
module providing a substitute for the header file.  When the list
"Portability problems not fixed by Gnulib" is empty, such a module is
not needed: No portability problems are known.  Otherwise, it indicates
that such a module would be useful but is not available: No one so far
found this header file important enough to contribute a substitute for
it.  If you need this particular header file, you may write to
`<bug-gnulib at gnu dot org>'.

   Gnulib module: float

   Portability problems fixed by Gnulib:
   * The conversion from `int' to `long double' in incorrect on some
     platforms: glibc 2.7 on Linux/SPARC64.

   * The values of `LDBL_*' macros are incorrect on some platforms: On
     OpenBSD 4.0, MirBSD 10, and BeOS, they are the same as the values
     of the `DBL_*' macros, although `long double' is a larger type than
     `double'.  On FreeBSD/x86 6.4, they represent the incorrect 53-bit
     precision assumptions in the compiler, not the real 64-bit
     precision at runtime.  On Linux/PowerPC with GCC 4.4, on AIX 7.1
     with GCC 4.2, and on IRIX 6.5, they don't reflect the "double
     double" representation of `long double' correctly.

   * The macro `FLT_ROUNDS' is a constant expression and does not
     represent the current rounding mode on some platforms: glibc 2.11,

   Gnulib module: stdalign

   Portability problems fixed by Gnulib:
   * This header file is missing on most circa-2011 platforms.

   * Clang 3.0's `<stdalign.h>' does not define `alignof'/`_Alignof'.

   * The `alignof' and `_Alignof' macros return too large values for
     the types `double' and `long long' in GCC 4.7.0.

   Portability problems not fixed by Gnulib:
   * `_Alignas' and `alignas' are not always supported; on platforms
     lacking support, the macro `__alignas_is_defined' is not defined.
     Supported compilers include GCC, IBM C, Sun C 5.11 and later, and
     MSVC 7.0 and later.

   * Some compilers do not support alignment via `alignas'/`_Alignas'
     of `auto' variables (i.e., variables on the stack).  They diagnose
     and ignore the alignment: Sun C 5.11.

   * Some linkers do not support operands of `_Alignas'/`alignas' that
     are greater than 8: mingw.

   * Some compilers require the operand of `_Alignas'/`alignas' to be a
     single integer constant, not an expression: MSVC 7.0 through at
     least 10.0.

   * The Sun C 5.11 compiler sometimes mishandles the alignment of
     multiple external variables that are declared close together with
     `_Alignas'/`alignas'.  This compiler bug causes the Gnulib module
     `stdalign-tests' to fail.  The Sun Studio Developer Bug Report
     Review Team assigned the internal review ID 2125432 (dated
     2011-11-01) to this issue.

   * `<stdalign.h>' must be #included before `_Alignas' and `_Alignof'
     can be used.

   * You cannot assume that `_Alignas' and `_Alignof' are reserved
     words; they might be macros.

   Portability problems fixed by Gnulib:
   * This header file is missing on some platforms: AIX 5.1, HP-UX 11,
     IRIX 6.5, OSF/1 5.1.

   * Some compilers have bugs relating to `bool'.

   * This header file defines `true' incorrectly on some platforms:
     OpenBSD 4.7 with gcc 2.95.

   Portability problems not fixed by Gnulib:
   * `<stdbool.h>' must be #included before `_Bool' can be used.

   * You cannot assume that `_Bool' is a typedef; it might be a macro.

   * Bit-fields of type `bool' are not supported.  Portable code should
     use `unsigned int foo : 1;' rather than `bool foo : 1;'.

   * Casts and automatic conversions to `bool' don't test against the
     zero value or the null pointer, as they should.  Such casts should
     only be used if the value is known to be equal to 0 or 1.

   * You cannot assume that casting a floating point literal to `bool'
     will result in a constant expression.

`http://www.opengroup.org/onlinepubs/9699919799/basedefs/stdint.h.html'

   Gnulib module: stdint

   Portability problems fixed by Gnulib:
   * This header file is missing on some platforms: OpenBSD 3.8, AIX
     5.1, HP-UX 11.11, IRIX 6.5, OSF/1 5.1, MSVC 9, Interix 3.5, BeOS.

   * This header file is very incomplete on some platforms.

   * The values of `SIG_ATOMIC_MIN' and `SIG_ATOMIC_MAX' are incorrect
     on some platforms: FreeBSD 6.2 / ia64.

   * The value of `WINT_MAX' is incorrect on some platforms: mingw.

   * The values of `INT8_MAX', `UINT8_MAX' etc. are not usable in
     preprocessor expressions on some platforms: HP-UX 11.23.

   * The macros `WCHAR_MIN' and `WCHAR_MAX' are not defined in
     `<stdint.h>' (only in `<wchar.h>') on some platforms: Dragonfly,
     BSDI.

   * On some hosts that predate C++11, when using C++ one must define
     `__STDC_CONSTANT_MACROS' to make visible the definitions of
     constant macros such as `INTMAX_C', and one must define
     `__STDC_LIMIT_MACROS' to make visible the definitions of limit
     macros such as `INTMAX_MAX'.

   Portability problems not fixed by Gnulib:
   * `{uint,int}_fast{8,16,32,64}_t' may not correspond to the fastest
     types available on the system.

   * Macros are used instead of typedefs.

   * Some C preprocessors mishandle constants that do not fit in `long
     int'.  For example, as of 2007, Sun C mishandles `#if LLONG_MIN <
     0' on a platform with 32-bit `long int' and 64-bit `long long int'.
     Some older preprocessors mishandle constants ending in `LL'.  To
     work around these problems, compute the value of expressions like
     `LONG_MAX < LLONG_MAX' at `configure'-time rather than at
     `#if'-time.

   The stdint.h module uses `#include_next'.  If you wish to install
the generated stdint.h file under another name, typically in order to
be able to use some of the types defined by stdint.h in your public
header file, you could use the following Makefile.am-snippet:


     BUILT_SOURCES += idn-int.h
     DISTCLEANFILES += idn-int.h
     nodist_include_HEADERS += idn-int.h

     idn-int.h:

   * You cannot assume that `_Noreturn' is a reserved word; it might be

   * On MSVC 9, `noreturn' expands to the empty token sequence, to avoid
     problems with standard headers that use `__declspec (noreturn)'
     directly.  Although the resulting code operates correctly, the
     compiler is not informed whether `noreturn' functions do not
     return, so it may generate incorrect warnings at compile-time, or
     code that is slightly less optimized.  This problem does not occur
     with `_Noreturn'.

     platforms: mingw, MSVC 9.

   * The macros `UTIME_NOW' and `UTIME_OMIT' are missing on some
     platforms.

   * On some platforms, `struct stat' does not include `st_atim',
     `st_mtim', or `st_ctim' members.  Use the gnulib module
     `stat-time' for accessors to portably get at subsecond resolution.

   Portability problems not fixed by Gnulib:
   * The macro `S_IFBLK' is missing on some platforms: MSVC 9.

   * On Windows platforms (excluding Cygwin), `st_ino' is always 0.

   * On OpenVMS, `st_ino' is an array of three `ino_t' values, not a
     single value.

   * To partially work around the previous two problems, you can test
     for nonzero `st_ino' and use the Gnulib `same-inode' module to
     compare nonzero values.  For example, `(a.st_ino && SAME_INODE (a,
     b))' is true if the `struct stat' values `a' and `b' are known to
     represent the same file, `(a.st_ino && !SAME_INODE (a, b))' is
     true if they are known to represent different files, and
     `!a.st_ino' is true if it is not known whether they represent
     different files.

   * On some platforms, two different files may have the same `st_dev'
     and `st_ino' values, even when `st_ino' is nonzero:
        * GNU/Linux NFS servers that export all local file systems as a
          single NFS file system, if a local `st_dev' exceeds 255, or
          if a local `st_ino' exceeds 16777215.

        * Network Appliance NFS servers in snapshot directories; see
          Network Appliance bug #195.

        * ClearCase MVFS; see bug id ATRia04618.
     One partial workaround is to compare other file metadata such as
     `st_mode' and `st_mtime' to detect this bug, but this approach
     does not work on files whose metadata are being changed by other
     programs.

   * On some file systems, `st_size' contains bogus information for
     symlinks; use the Gnulib module `areadlink-with-size' for a better
     way to get symlink contents.

8 ISO C and POSIX Function Substitutes
**************************************

   This chapter describes which functions and function-like macros
specified by ISO C or POSIX are substituted by Gnulib, which
portability pitfalls are fixed by Gnulib, and which (known) portability
problems are not worked around by Gnulib.

   The notation "Gnulib module: --" means that Gnulib does not provide a
module providing a substitute for the function.  When the list
"Portability problems not fixed by Gnulib" is empty, such a module is
not needed: No portability problems are known.  Otherwise, it indicates
that such a module would be useful but is not available: No one so far
found this function important enough to contribute a substitute for it.
If you need this particular function, you may write to
`<bug-gnulib at gnu dot org>'.

   * On Windows platforms (excluding Cygwin), error codes for `accept'
     are not placed in `errno', and `WSAGetLastError' must be used

     that id of the file alone.

   * When applied to a symbolic link, some implementations don't
     dereference the symlink, i.e. they behave like `lchown'.

   * This function may overflow its internal buffer if an invalid year
     is passed.

   * The `ctime' function need not be reentrant, and consequently is
     not required to be thread safe.  Implementations of `ctime'
     typically write the time stamp into static buffer.  If two threads
     call `ctime' at roughly the same time, you might end up with the
     wrong date in one of the threads, or some undefined string.  There
     is a re-entrant interface `ctime_r'.

   A more flexible function is `strftime'.  However, note that it is
locale dependent.

   * This function is missing on some platforms: mingw, MSVC 9.

   * This function may put more than 26 bytes into the argument buffer
     if an invalid year is passed.

   `ctime_r' takes a pre-allocated buffer and length of the buffer, and
returns `NULL' on errors.  The input buffer should be at least 26 bytes
in size.  The output string is locale-independent.  However, years can
have more than 4 digits if `time_t' is sufficiently wide, so the length
of the required output buffer is not easy to determine.  Increasing the
buffer size when `ctime_r' returns `NULL' is not necessarily
sufficient.  The `NULL' return value could mean some other error
condition, which will not go away by increasing the buffer size.

   A more flexible function is `strftime'.  However, note that it is
locale dependent.

   * This function is declared in different header files (namely,
     `<io.h>' or `<direct.h>') on some platforms: mingw, MSVC 9.

   * On glibc platforms, `getcwd (NULL, n)' allocates memory for the
     result.  On some other platforms, this call is not allowed.

   * On some platforms, the prototype for `getcwd' uses `int' instead
     of `size_t' for the size argument when using non-standard headers,
     and the declaration is missing from `<unistd.h>': mingw, MSVC 9.

   * On some platforms, `getcwd (buf, 0)' fails with `ERANGE' instead
     of the required `EINVAL': mingw, MSVC 9.

   Portability problems fixed by Gnulib module `getcwd':
   * This function is missing on some older platforms.

     MacOS X 10.5, FreeBSD 6.4, NetBSD 5.1, OpenBSD 4.9, AIX 7.1.

   Portability problems not fixed by Gnulib:
   * When using `getcwd(NULL, nonzero)', some platforms, such as glibc
     or cygwin, allocate exactly `nonzero' bytes and fail with `ERANGE'
     if it was not big enough, while other platforms, such as FreeBSD,
     mingw, or MSVC 9, ignore the size argument and allocate whatever
     size is necessary.  If this call succeeds, an application cannot
     portably access beyond the string length of the result.

8.355 `getopt'
==============

   POSIX specification:
`http://www.opengroup.org/onlinepubs/9699919799/functions/getopt.html'

   Gnulib module: getopt-posix or getopt-gnu

   The module `getopt-gnu' has support for "long options" and for
"options that take optional arguments".  Compared to the API defined by
POSIX, it adds a header file `<getopt.h>' and a function `getopt_long'.

   Portability problems fixed by either Gnulib module `getopt-posix' or
`getopt-gnu':
   * The `getopt' function keeps some internal state that cannot be
     explicitly reset on some platforms: mingw.

   * The value of `optind' after a missing required argument is wrong
     on some platforms: MacOS 10.5, AIX 7.1.

   Portability problems fixed by Gnulib module `getopt-gnu':
   * This function is missing on some platforms: MSVC 9.

   * The function `getopt' does not support the `+' flag in the options
     string on some platforms: MacOS X 10.5, AIX 5.2, HP-UX 11, IRIX
     6.5, OSF/1 5.1, Solaris 11 2010-11.

   * The function `getopt' does not obey the combination of `+' and `:'
     flags in the options string on some platforms: glibc 2.11.

   * The function `getopt' does not obey the `-' flag in the options
     string when `POSIXLY_CORRECT' is set on some platforms: Cygwin
     1.7.0.

   * The function `getopt' does not support options with optional
     arguments on some platforms: MacOS X 10.5, OpenBSD 4.0, AIX 5.2,
     HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 11 2010-11, Cygwin 1.5.x.

   * The function `getopt_long' is missing on some platforms: AIX 5.1,
     HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 9, MSVC 9, Interix 3.5.

   * The function `getopt_long_only' is missing on some platforms:
     MacOS X 10.3, FreeBSD 5.2.1, NetBSD 5.0, AIX 5.1, HP-UX 11, IRIX
     6.5, OSF/1 5.1, Solaris 9, mingw, MSVC 9, Interix 3.5.

   * This function crashes if the option string includes `W;' on some
     platforms: glibc 2.14.

   Portability problems not fixed by Gnulib:
   * The default behavior of the glibc implementation of `getopt' allows
     mixing option and non-option arguments on the command line in any
     order.  Other implementations, such as the one in Cygwin, enforce
     strict POSIX compliance: they require that the option arguments
     precede the non-option arguments.  This is something to watch out
     in your program's testsuite.

   * The glibc implementation allows a complete reset of the
     environment, including re-checking for `POSIXLY_CORRECT', by
     setting `optind' to 0.  Several BSD implementations provide
     `optreset', causing a reset by setting it non-zero, although it
     does not necessarily re-read `POSIXLY_CORRECT'.  Solaris `getopt'
     does not support either reset method, but does not maintain state
     that needs the extra level of reset.

   * On some platforms, this function does not set the stream error
     indicator on attempts to write to a read-only stream: glibc 2.13,
     Cygwin 1.7.9.

   Note: This function's behaviour depends on the locale, but does not
support the multibyte characters that occur in strings in locales with
`MB_CUR_MAX > 1' (this includes all the common UTF-8 locales).  There
are four alternative APIs:

`c_ispunct'
     This function operates in a locale independent way and returns
     true only for ASCII characters.  It is provided by the Gnulib
     module `c-ctype'.

`iswpunct'
     This function operates in a locale dependent way, on wide
     characters.  In order to use it, you first have to convert from
     multibyte to wide characters, using the `mbrtowc' function.  It is
     provided by the Gnulib module `wctype'.

`mb_ispunct'
     This function operates in a locale dependent way, on multibyte
     characters.  It is provided by the Gnulib module `mbchar'.

`uc_is_punct'
     This function operates in a locale independent way, on Unicode

   Note: This function's behaviour depends on the locale, but does not
support the multibyte characters that occur in strings in locales with
`MB_CUR_MAX > 1' (this includes all the common UTF-8 locales).  There
are four alternative APIs:

`c_isxdigit'
     This function operates in a locale independent way and returns
     true only for ASCII characters.  It is provided by the Gnulib
     module `c-ctype'.

`iswxdigit'
     This function operates in a locale dependent way, on wide
     characters.  In order to use it, you first have to convert from
     multibyte to wide characters, using the `mbrtowc' function.  It is
     provided by the Gnulib module `wctype'.

`mb_isxdigit'
     This function operates in a locale dependent way, on multibyte
     characters.  It is provided by the Gnulib module `mbchar'.

`uc_is_xdigit'
     This function operates in a locale independent way, on Unicode
     characters.  It is provided by the Gnulib module
     `unictype/ctype-xdigit'.

   Portability problems fixed by Gnulib:
   * On platforms where `off_t' is a 32-bit type, `lseek' does not work

   * This function mistakenly succeeds on pipes on some platforms:
     mingw, MSVC 9, BeOS.

   Portability problems not fixed by Gnulib:
   * POSIX does not specify which file descriptors support seeking and
     which don't.  In practice, regular files and block devices support
     seeking, and ttys, pipes, and most character devices don't support
     it.

   * When the third argument is invalid, POSIX says that `lseek' should
     set `errno' to `EINVAL' and return -1, but in this situation a
     `SIGSYS' signal is raised on some platforms: IRIX 6.5.

   * When the `lseek' function fails, POSIX says that the file offset
     remains unchanged.  But on some platforms, attempting to set a
     negative file offset fails and sets the file offset to 0: BeOS.

   * For symlinks, when the argument ends in a slash, some platforms
     don't dereference the argument: Solaris 9.

   * On some platforms, `lstat("file/",buf)' succeeds instead of
     failing with `ENOTDIR'.  Solaris 9.

   * On Windows platforms (excluding Cygwin), symlinks are not

   Extension: Gnulib provides a module `malloc-gnu' that substitutes a
`malloc' implementation that behaves more like the glibc implementation,
regarding the result of `malloc (0)'.

   Portability problems not fixed by Gnulib:
   * It is not portable to call `realloc' with a size of 0.  With a
     NULL pointer argument, this is the same ambiguity as `malloc (0)'
     on whether a unique zero-size object is created.  With a non-NULL
     pointer argument, C99 requires that if `realloc (p, 0)' returns
     `NULL' then `p' is still valid.  Among implementations that obey
     C99, behavior varies on whether `realloc (p, 0)' always fails and
     leaves `p' valid, or usually succeeds and returns a unique
     zero-size object; either way, a program not suspecting these
     semantics will leak memory (either the still-valid `p', or the
     non-NULL return value).  Meanwhile, several implementations violate
     C99, by always calling `free (p)' but returning NULL: glibc, Cygwin

   Extension: Gnulib provides a module `realloc-gnu' that substitutes a
`realloc' implementation that behaves more like the glibc
implementation.

   POSIX specification:
`http://www.opengroup.org/onlinepubs/9699919799/functions/rename.html'

   Gnulib module: rename

   Portability problems fixed by Gnulib:
   * This function does not allow trailing slashes when creating a
     destination directory, as in `rename("dir","new/")': NetBSD 1.6.

   * This function does not reject trailing slashes on the destination
     for non-directories on some platforms, as in
     `rename("file","new/")': AIX 7.1, Solaris 11 2011-11, Cygwin
     1.5.x, mingw, MSVC 9.

   * This function does not reject trailing slashes on symlinks to
     non-directories on some platforms, as in
     `rename("link-to-file/","f")': FreeBSD 7.2.

   * This function ignores trailing slashes on symlinks on some
     platforms, such that `rename("link/","new")' corrupts `link':
     Solaris 9.

   * This function incorrectly reduces the link count when comparing two
     spellings of a hard link on some platforms: NetBSD 1.6, Cygwin
     1.5.x.

   * This function will not always replace an existing destination on
     some platforms: Cygwin 1.5.x, mingw, MSVC 9.  However, the
     replacement is not atomic for directories, and may end up losing
     the empty destination if the source could not be renamed.

   * This function mistakenly allows names ending in `.' or `..' on
     some platforms: Cygwin 1.5.x, mingw, MSVC 9.

   * This function does not reject attempts to rename existing
     directories and non-directories onto one another on some platforms:
     Cygwin 1.5.x, mingw, MSVC 9.

   * This function does not allow trailing slashes on source
     directories on older platforms, as in `rename("dir/","new")':
     SunOS 4.1.

   Portability problems not fixed by Gnulib:
   * POSIX requires that `rename("symlink-to-dir/","dir2")' rename
     `dir' and leave `symlink-to-dir' dangling; likewise, it requires
     that `rename("dir","dangling/")' rename `dir' so that `dangling'
     is no longer a dangling symlink.  This behavior is
     counter-intuitive, so on some systems, `rename' fails with
     `ENOTDIR' if either argument is a symlink with a trailing slash:
     glibc, OpenBSD, Cygwin 1.7.

   * After renaming a non-empty directory over an existing empty
     directory, the old directory name is still visible through the
     `stat' function for 30 seconds after the rename, on NFS file
     systems, on some platforms: Linux 2.6.18.

   * This function will not rename a source that is currently opened by
     any process: mingw, MSVC 9.

   * This function does not reject trailing slashes on non-directories
     on some platforms, as in `renameat(fd,"file",fd,"new/")': Solaris
     11 2011-11.

   * This function ignores trailing slashes on symlinks on some
     platforms, such that `renameat(fd,"link/",fd,"new")' corrupts
     `link': Solaris 9.

   * This function is declared in `<unistd.h>' instead of `<stdio.h>'
     on some platforms: Solaris 11 2011-11.

   * This function is missing on some platforms: glibc 2.3.6, MacOS X

     HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 8, Cygwin 1.5.x, mingw,
     MSVC 9, Interix 3.5, BeOS.  But the replacement function is not
     safe to be used in libraries and is not multithread-safe.

   Portability problems not fixed by Gnulib:
   * POSIX requires that `renameat(fd,"symlink-to-dir/",fd,"dir2")'

   Portability problems fixed by Gnulib:
   * On Windows platforms (excluding Cygwin), `select' can only be

     regular file descriptors.

   * On Windows platforms (excluding Cygwin), error codes for `accept'
     are not placed in `errno', and `WSAGetLastError' must be used
     instead.

   * This function fails when the `nfds' argument is 0 on some
     platforms: Interix 3.5.

   Portability problems not fixed by Gnulib:
   * When you call `select' with a timeout, some implementations modify
     the timeout parameter so that upon return from the function, it
     contains the amount of time not slept.  Other implementations
     leave the timeout parameter unmodified.

   * On BeOS, `select' can only be called on descriptors created by the
     `socket' function, not on regular file descriptors.

   * On Solaris 2.6 and older, `select' applied to a file descriptor
     opened for reading and associated with `/dev/null' hangs, waiting
     for input, when instead it should return immediately.

   * On Linux, when some file descriptor refers to a regular file,
     `select' may fail, setting `errno' to `EBADF'.

   * This function is declared in `<unistd.h>', not `<sys/select.h>',

     On some platforms (BSD? SystemV? Linux?), you need to use the

   * This function crashes when invoked with invalid arguments on some

   * On System V platforms, when the signal is triggered, the kernel
     uninstalls the handler (i.e. resets the signal's action to
     SIG_DFL) before invoking the handler.  This opens the door to race
     conditions: undesired things happen if the signal is triggered
     twice and the signal handler was not quick enough reinstalling
     itself as a handler.  On BSD platforms and glibc platforms, on the
     other hand, when the signal is triggered, the kernel blocks the
     signal before invoking the handler.  This is saner, but POSIX
     still allows either behavior.  To avoid this problem, use
     `sigaction' instead of `signal'.

     GB.  (Cf. `AC_SYS_LARGEFILE'.)

   * On some platforms, `stat("link-to-file/",buf)' succeeds instead of
     failing with `ENOTDIR'.  FreeBSD 7.2, AIX 7.1, Solaris 9.

   * On some platforms, `stat(".",buf)' and `stat("./",buf)' give
     different results: mingw, MSVC 9.

   Portability problems not fixed by Gnulib:
   * *Note sys/stat.h::, for general portability problems with `struct
     stat'.

   * Cygwin's `stat' function sometimes sets `errno' to `EACCES' when
     `ENOENT' would be more appropriate.

   * Because of the definition of `struct stat', it is not possible to
     portably replace `stat' via an object-like macro.  Therefore,
     expressions such as `(islnk ? lstat : stat) (name, buf)' are not
     portable, and should instead be written `islnk ? lstat (name, buf)
     : stat (name, buf)'.

     FreeBSD 8.2.

   * This function produces a different string for `0' than `strerror'
     on some platforms: MacOS X 10.5.

   * This function always fails when the third argument is less than 80
     on some platforms: HP-UX 11.31.

   * When the buffer is too small and the value is in range, this
     function does not fail, but instead truncates the result and
     returns 0 on some platforms: AIX 6.1, OSF/1 5.1.

   * When the value is not in range or the buffer is too small, this
     function fails to leave a NUL-terminated string in the buffer on
     some platforms: glibc 2.13, FreeBSD 8.2, Solaris 10.

   * When the value is out of range but the buffer is too small, this
     function does not always return the longest possible string on some
     platforms: OpenBSD 4.7.

     This is counter-intuitive, so some systems fail with `ENOTDIR'

     end up truncating timestamps to less resolution than supported by
     the file system.  Furthermore, the replacement function is not
     safe to be used in libraries and is not multithread-safe.

   * This function returns a bogus value instead of failing with

   * This function fails with `ENOSYS' if passed the flag
     `AT_SYMLINK_NOFOLLOW' on a regular file: Linux kernel 2.6.22.

   * When using `UTIME_OMIT' or `UTIME_NOW', some systems require the
     `tv_sec' argument to be 0, and don't necessarily handle all file
     permissions in the manner required by POSIX: Linux kernel 2.6.25.

   * When using `UTIME_OMIT' for the modification time, but specifying
     an access time, some systems fail to update the change time: Linux
     kernel 2.6.32.

   * Out-of-range values of `tv_nsec' do not lead to a failure on some
     platforms: Linux kernel 2.6.22.19 on hppa.

   Portability problems not fixed by Gnulib:
   * On some platforms, timestamps of symbolic links cannot be
     modified, so the replacement fails with `ENOSYS' if passed the flag
     `AT_SYMLINK_NOFOLLOW' on a symlink.

   * The mere act of using `lstat' modifies the access time of symlinks
     on some platforms, so `utimensat' with `AT_SYMLINK_NOFOLLOW' can
     only effectively change modification time: Cygwin.

   * The mere act of using `stat' modifies the access time of
     directories on some platforms, so `utimensat' can only effectively
     change directory modification time: Cygwin 1.5.x.

   The gnulib module fdutimensat provides a similar interface.

9 Past POSIX Function Substitutes
*********************************

   This chapter describes which functions and function-like macros
specified by older versions of POSIX (POSIX:2001) are substituted by
Gnulib, which portability pitfalls are fixed by Gnulib, and which
(known) portability problems are not worked around by Gnulib.

   The notation "Gnulib module: --" means that Gnulib does not provide a
module providing a substitute for the function.  When the list
"Portability problems not fixed by Gnulib" is empty, such a module is
not needed: No portability problems are known.  Otherwise, it indicates
that such a module would be useful but is not available: No one so far
found this function important enough to contribute a substitute for it.
If you need this particular function, you may write to
`<bug-gnulib at gnu dot org>'.

11 Glibc Function Substitutes
*****************************

   This chapter describes which functions and function-like macros
provided as extensions by at least GNU libc are also supported by
Gnulib, which portability pitfalls are fixed by Gnulib, and which
(known) portability problems are not worked around by Gnulib.

   The notation "Gnulib module: --" means that Gnulib does not provide a
module providing a substitute for the function.  When the list
"Portability problems not fixed by Gnulib" is empty, such a module is
not needed: No portability problems are known.  Otherwise, it indicates
that such a module would be useful but is not available: No one so far
found this function important enough to contribute a substitute for it.
If you need this particular function, you may write to
`<bug-gnulib at gnu dot org>'.

   This list of functions is sorted according to the header that
declares them.

   * On systems with SELinux support, this module provides a wrapper
     for the `fgetfilecon' function that insulates the caller from
     API-nonconforming behavior.  Without this wrapper, `fgetfilecon'
     can return `0' and set the `context' pointer to NULL, and in
     another scenario can return `10' and set the `context' pointer to
     `unlabeled'.  This wrapper returns `-1' in each case and sets
     `errno' to `ENOTSUP' and `ENODATA' respectively.  While the
     conditions that can provoke such behavior are rare, the average
     caller does not handle them because the possibility of such
     behavior is not documented.

     3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris
     11 2011-11, mingw, MSVC 9, Interix 3.5, BeOS.  On those platforms,
     this module provides a stub that always sets `errno' to `ENOTSUP'
     and returns `-1'.

   * On systems with SELinux support, this module provides a wrapper
     for the `lgetfilecon' function that insulates the caller from
     API-nonconforming behavior.  Without this wrapper, `lgetfilecon'
     can return `0' and set the `context' pointer to NULL, and in
     another scenario can return `10' and set the `context' pointer to
     `unlabeled'.  This wrapper returns `-1' in each case and sets
     `errno' to `ENOTSUP' and `ENODATA' respectively.  While the
     conditions that can provoke such behavior are rare, the average
     caller does not handle them because the possibility of such
     behavior is not documented.

   Portability problems not fixed by Gnulib:

   The gnulib module `clean-temp' can create temporary files that will
not be left behind after signals such as SIGINT.

   Other problems of this function:
   * There is an inherent race between calling this function and
     performing some action based on the results; you should think
     twice before trusting this function, especially in a set-uid or
     set-gid program.

   * This function does not have an option for not following symbolic
     links (like `stat' versus `lstat').  If you need this option, use
     the Gnulib module `faccessat' with the `AT_EACCESS' flag.

12.1 alloca
===========

   The alloca module provides for a function `alloca' which allocates
memory on the stack, where the system allows it. A memory block
allocated with `alloca' exists only until the function that calls
`alloca' returns or exits abruptly.

   There are a few systems where this is not possible: HP-UX systems,
and some other platforms when the C++ compiler is used. On these
platforms the alloca module provides a `malloc' based emulation. This
emulation will not free a memory block immediately when the calling
function returns, but rather will wait until the next `alloca' call
from a function with the same or a shorter stack length. Thus, in some
cases, a few memory blocks will be kept although they are not needed
any more.

   The user can `#include <alloca.h>' and use `alloca' on all platforms.
Note that the `#include <alloca.h>' must be the first one after the
autoconf-generated `config.h', for AIX 3 compatibility. Thanks to IBM
for this nice restriction!

   Note that GCC 3.1 and 3.2 can _inline_ functions that call `alloca'.
When this happens, the memory blocks allocated with `alloca' will not be
freed until _the end of the calling function_. If this calling function
runs a loop calling the function that uses `alloca', the program easily
gets a stack overflow and crashes. To protect against this compiler
behaviour, you can mark the function that uses `alloca' with the
following attribute:

     #ifdef __GNUC__
     __attribute__ ((__noinline__))
     #endif

   An alternative to this module is the `alloca-opt' module.

12.2 alloca-opt
===============

   The alloca-opt module provides for a function `alloca' which
allocates memory on the stack, where the system allows it. A memory
block allocated with `alloca' exists only until the function that calls
`alloca' returns or exits abruptly.

   There are a few systems where this is not possible: HP-UX systems,
and some other platforms when the C++ compiler is used. On these
platforms the alloca-opt module provides no replacement, just a
preprocessor macro HAVE_ALLOCA.

   The user can `#include <alloca.h>' on all platforms, and use
`alloca' on those platforms where the preprocessor macro HAVE_ALLOCA
evaluates to true. If HAVE_ALLOCA is false, the code should use a
heap-based memory allocation based on `malloc' or - in C++ - `new'.
Note that the `#include <alloca.h>' must be the first one after the
autoconf-generated `config.h', for AIX 3 compatibility. Thanks to IBM
for this nice restriction!

   Note that GCC 3.1 and 3.2 can _inline_ functions that call `alloca'.
When this happens, the memory blocks allocated with `alloca' will not be
freed until _the end of the calling function_. If this calling function
runs a loop calling the function that uses `alloca', the program easily

File: gnulib.info,  Node: Safe Allocation Macros,  Next: Compile-time Assertions,  Prev: alloca-opt,  Up: Particular Modules

12.3 Safe Allocation Macros
===========================

   The standard C library malloc/realloc/calloc/free APIs are prone to a
number of common coding errors.  The `safe-alloc' module provides
macros that make it easier to avoid many of them.  It still uses the
standard C allocation functions behind the scenes.

   Some of the memory allocation mistakes that are commonly made are

   * passing the incorrect number of bytes to `malloc', especially when
     allocating an array,

   * fail to check the return value of `malloc' and `realloc' for
     errors,

   * forget to fully initialize memory just allocated with `malloc',

   * duplicate calls to `free' by forgetting to set the pointer
     variable to `NULL',

   * leaking memory in calls to `realloc' when that call fails.

   The `safe-alloc' module addresses these problems in the following
way:

   * It defines macros that wrap around the standard C allocation
     functions.  That makes it possible to use the compiler's knowledge
     of the size of objects for allocation; it also allows setting
     pointers passed in as arguments when appropriate.

   * It uses return values only for a success/failure error condition
     flag, and annotates them with GCC's `__warn_unused_result__'
     attribute.

   * It uses `calloc' instead of `malloc'.

 -- Macro: int ALLOC (ptr)
     Allocate `sizeof(*ptr)' bytes of memory and store the address of
     allocated memory in `ptr'.  Fill the newly allocated memory with
     zeros.

     Returns -1 on failure, 0 on success.

 -- Macro: int ALLOC_N (ptr, count)
     Allocate an array of `count' elements, each `sizeof(*ptr)' bytes
     long, and store the address of allocated memory in `ptr'.  Fill
     the newly allocated memory with zeros.

     Returns -1 on failure, 0 on success.

 -- Macro: int ALLOC_N_UNINITIALIZED (ptr, count)
     Allocate an array of `count' elements, each `sizeof(*ptr)' bytes
     long, and store the address of allocated memory in `ptr'.  The
     allocated memory is not initialized.

     Returns -1 on failure, 0 on success.

 -- Macro: int REALLOC_N (ptr, count)
     Reallocate the memory pointed to by `ptr' to be big enough to hold
     at least `count' elements, each `sizeof(*ptr)' bytes long, and
     store the address of allocated memory in `ptr'.  If reallocation
     fails, the `ptr' variable is not modified.

     Returns -1 on failure, 0 on success.

 -- Macro: void FREE (ptr)
     Free the memory stored in `ptr' and set `ptr' to `NULL'.


File: gnulib.info,  Node: Compile-time Assertions,  Next: Integer Properties,  Prev: Safe Allocation Macros,  Up: Particular Modules

12.4 Compile-time Assertions
============================

   The `verify' module supports compile-time tests, as opposed to the
standard `assert' macro which supports only runtime tests.  Since the
tests occur at compile-time, they are more reliable, and they require
no runtime overhead.

   This module provides a header file `verify.h' that defines two
macros: `verify (V)' and `verify_expr (V, EXPR)'.  Both accept an
integer constant expression argument V and verify that it is nonzero.
If not, a compile-time error results.

   `verify (V);' is a declaration; it can occur outside of functions.
In contrast, `verify_expr (V, EXPR)' is an expression that returns the
value of EXPR; it can be used in macros that expand to expressions.  If
EXPR is an integer constant expression, then `verify_expr (V, EXPR)' is
also an integer constant expression.  Although EXPR and `verify_expr
(V, EXPR)' are guaranteed to have the same side effects and value and
type (after integer promotion), they need not have the same type if
EXPR's type is an integer that is narrower than `int' or `unsigned int'.

   V should be an integer constant expression in the sense of the C
standard.  Its leaf operands should be integer, enumeration, or
character constants; or `sizeof' expressions that return constants; or
floating constants that are the immediate operands of casts.  Outside a
`sizeof' subexpression, V should not contain any assignments, function
calls, comma operators, casts to non-integer types, or subexpressions
whose values are outside the representable ranges for their types.  If
V is not an integer constant expression, then a compiler might reject a
usage like `verify (V);' even when V is nonzero.

   Although the standard `assert' macro is a runtime test, C11
specifies a builtin `_Static_assert (V, STRING-LITERAL)', its
`assert.h' header has a similar macro named `static_assert', and C++11
has a similar `static_assert' builtin.  These builtins and macros differ
from `verify' in two major ways.  First, they can also be used within a
`struct' or `union' specifier, in place of an ordinary member
declaration.  Second, they require the programmer to specify a
compile-time diagnostic as a string literal.

   Here are some example uses of `verify' and `verify_expr'.

     #include <verify.h>

     #include <limits.h>
     #include <time.h>

     /* Verify that time_t is an integer type.  */
     verify ((time_t) 1.5 == 1);

     /* Verify that time_t is no smaller than int.  */
     verify (sizeof (int) <= sizeof (time_t));

     /* Verify that time_t is signed.  */
     verify ((time_t) -1 < 0);

     /* Verify that time_t uses two's complement representation.  */
     verify (~ (time_t) -1 == 0);

     /* Return the maximum value of the integer type T,
        verifying that T is an unsigned integer type.
        The cast to (T) is outside the call to verify_expr
        so that the result is of type T
        even when T is narrower than unsigned int.  */
     #define MAX_UNSIGNED_VAL(t) \
        ((T) verify_expr (0 < (T) -1, -1))

12.5 Integer Properties
=======================

   The `intprops' module consists of an include file `<intprops.h>'
that defines several macros useful for testing properties of integer
types.

   Integer overflow is a common source of problems in programs written
in C and other languages.  In some cases, such as signed integer
arithmetic in C programs, the resulting behavior is undefined, and
practical platforms do not always behave as if integers wrap around
reliably.  In other cases, such as unsigned integer arithmetic in C,
the resulting behavior is well-defined, but programs may still
misbehave badly after overflow occurs.

   Many techniques have been proposed to attack these problems.  These
include precondition testing, GCC's `-ftrapv' option, GCC's
no-undefined-overflow branch, the As-if Infinitely Ranged (AIR) model
implemented in Clang, saturation semantics where overflow reliably
yields an extreme value, the RICH static transformer to an
overflow-checking variant, and special testing methods.  For more
information about these techniques, see: Dannenberg R, Dormann W,
Keaton D _et al._, As-if Infinitely Ranged integer model - 2nd ed.
(http://www.sei.cmu.edu/library/abstracts/reports/10tn008.cfm),
Software Engineering Institute Technical Note CMU/SEI-2010-TN-008,
April 2010.

   Gnulib supports the precondition testing technique, as this is easy
to support portably.  There are two families of precondition tests: the
first, for integer ranges, has a simple and straightforward
implementation, while the second, for integer types, is easier to use.

* Menu:

* Integer Type Determination::  Whether a type has integer properties.
* Integer Bounds::              Bounds on integer values and representations.
* Integer Range Overflow::      Integer overflow checking if bounds are known.
* Integer Type Overflow::       General integer overflow checking.


File: gnulib.info,  Node: Integer Type Determination,  Next: Integer Bounds,  Up: Integer Properties

12.5.1 Integer Type Determination
---------------------------------

   `TYPE_IS_INTEGER (T)' expands to a constant expression that is 1 if
the arithmetic type T is an integer type.  `_Bool' counts as an integer
type.

   `TYPE_SIGNED (T)' expands to a constant expression that is 1 if the
arithmetic type T is a signed integer type or a floating type.  If T is
an integer type, `TYPE_SIGNED (T)' expands to an integer constant
expression.

   Example usage:

     #include <intprops.h>
     #include <time.h>
     enum
     {
       time_t_is_signed_integer =
         TYPE_IS_INTEGER (time_t) && TYPE_SIGNED (time_t)
     };


File: gnulib.info,  Node: Integer Bounds,  Next: Integer Range Overflow,  Prev: Integer Type Determination,  Up: Integer Properties

12.5.2 Integer Bounds
---------------------

   `INT_BUFSIZE_BOUND (T)' expands to an integer constant expression
that is a bound on the size of the string representing an integer type
or expression T in decimal notation, including the terminating null
character and any leading `-' character.  For example, if
`INT_STRLEN_BOUND (int)' is 12, any value of type `int' can be
represented in 12 bytes or less, including the terminating null.  The
bound is not necessarily tight.

   Example usage:

     #include <intprops.h>
     #include <stdio.h>
     int
     int_strlen (int i)
     {
       char buf[INT_BUFSIZE_BOUND (int)];
       return sprintf (buf, "%d", i);
     }

   `INT_STRLEN_BOUND (T)' expands to an integer constant expression
that is a bound on the length of the string representing an integer
type or expression T in decimal notation, including any leading `-'
character.  This is one less than `INT_BUFSIZE_BOUND (T)'.

   `TYPE_MINIMUM (T)' and `TYPE_MAXIMUM (T)' expand to integer constant
expressions equal to the minimum and maximum values of the integer type
T.  These expressions are of the type T (or more precisely, the type T
after integer promotions).

   Example usage:

     #include <stdint.h>
     #include <sys/types.h>
     #include <intprops.h>
     int
     in_off_t_range (intmax_t a)
     {
       return TYPE_MINIMUM (off_t) <= a && a <= TYPE_MAXIMUM (off_t);
     }

12.5.3 Integer Range Overflow
-----------------------------

   These macros yield 1 if the corresponding C operators might not yield
numerically correct answers due to arithmetic overflow.  They do not
rely on undefined or implementation-defined behavior.  They expand to
integer constant expressions if their arguments are.  Their
implementations are simple and straightforward, but they are typically
harder to use than the integer type overflow macros.  *Note Integer
Type Overflow::.

   Although the implementation of these macros is similar to that
suggested in Seacord R, The CERT C Secure Coding Standard (2009,
revised 2011), in its two sections "INT30-C. Ensure that unsigned
integer operations do not wrap
(https://www.securecoding.cert.org/confluence/display/seccode/INT30-C.+Ensure+that+unsigned+integer+operations+do+not+wrap)"
and "INT32-C. Ensure that operations on signed integers do not result
in overflow
(https://www.securecoding.cert.org/confluence/display/seccode/INT32-C.+Ensure+that+operations+on+signed+integers+do+not+result+in+overflow)",
Gnulib's implementation was derived independently of CERT's suggestions.

   Example usage:

     #include <intprops.h>
     void
     print_product (long int a, long int b)
     {
       if (INT_MULTIPLY_RANGE_OVERFLOW (a, b, LONG_MIN, LONG_MAX))
         printf ("multiply would overflow");
       else
         printf ("product is %ld", a * b);
     }

These macros have the following restrictions:

   * Their arguments must be integer expressions.

   * They may evaluate their arguments zero or multiple times, so the
     arguments should not have side effects.

   * The arithmetic arguments (including the MIN and MAX arguments)
     must be of the same integer type after the usual arithmetic
     conversions, and the type must have minimum value MIN and maximum
     MAX.  Unsigned values should use a zero MIN of the proper type,
     for example, `(unsigned int) 0'.

   These macros are tuned for constant MIN and MAX.  For commutative
operations such as `A + B', they are also tuned for constant B.

`INT_ADD_RANGE_OVERFLOW (A, B, MIN, MAX)'
     Yield 1 if `A + B' would overflow in [MIN,MAX] integer arithmetic.
     See above for restrictions.

`INT_SUBTRACT_RANGE_OVERFLOW (A, B, MIN, MAX)'
     Yield 1 if `A - B' would overflow in [MIN,MAX] integer arithmetic.
     See above for restrictions.

`INT_NEGATE_RANGE_OVERFLOW (A, MIN, MAX)'
     Yield 1 if `-A' would overflow in [MIN,MAX] integer arithmetic.
     See above for restrictions.

`INT_MULTIPLY_RANGE_OVERFLOW (A, B, MIN, MAX)'
     Yield 1 if `A * B' would overflow in [MIN,MAX] integer arithmetic.
     See above for restrictions.

`INT_DIVIDE_RANGE_OVERFLOW (A, B, MIN, MAX)'
     Yield 1 if `A / B' would overflow in [MIN,MAX] integer arithmetic.
     See above for restrictions.  Division overflow can happen on two's
     complement hosts when dividing the most negative integer by -1.
     This macro does not check for division by zero.

`INT_REMAINDER_RANGE_OVERFLOW (A, B, MIN, MAX)'
     Yield 1 if `A % B' would overflow in [MIN,MAX] integer arithmetic.
     See above for restrictions.  Remainder overflow can happen on
     two's complement hosts when dividing the most negative integer by
     -1; although the mathematical result is always 0, in practice some
     implementations trap, so this counts as an overflow.  This macro
     does not check for division by zero.

`INT_LEFT_SHIFT_RANGE_OVERFLOW (A, B, MIN, MAX)'
     Yield 1 if `A << B' would overflow in [MIN,MAX] integer
     arithmetic.  See above for restrictions.  Here, MIN and MAX are
     for A only, and B need not be of the same type as the other
     arguments.  The C standard says that behavior is undefined for
     shifts unless 0<=B<W where W is A's word width, and that when A is
     negative then `A << B' has undefined behavior and `A >> B' has
     implementation-defined behavior, but this macro does not check
     these other restrictions.


File: gnulib.info,  Node: Integer Type Overflow,  Prev: Integer Range Overflow,  Up: Integer Properties

12.5.4 Integer Type Overflow
----------------------------

   These macros yield 1 if the corresponding C operators might not yield
numerically correct answers due to arithmetic overflow of an integer
type.  They work correctly on all known practical hosts, and do not
rely on undefined behavior due to signed arithmetic overflow.  They
expand to integer constant expressions if their arguments are.  They
are easier to use than the integer range overflow macros (*note Integer
Range Overflow::).

   Example usage:

     #include <intprops.h>
     void
     print_product (long int a, long int b)
     {
       if (INT_MULTIPLY_OVERFLOW (a, b))
         printf ("multiply would overflow");
       else
         printf ("product is %ld", a * b);
     }

These macros have the following restrictions:

   * Their arguments must be integer expressions.

   * They may evaluate their arguments zero or multiple times, so the
     arguments should not have side effects.

   These macros are tuned for their last argument being a constant.

`INT_ADD_OVERFLOW (A, B)'
     Yield 1 if `A + B' would overflow.  See above for restrictions.

`INT_SUBTRACT_OVERFLOW (A, B)'
     Yield 1 if `A - B' would overflow.  See above for restrictions.

`INT_NEGATE_OVERFLOW (A)'
     Yields 1 if `-A' would overflow.  See above for restrictions.

`INT_MULTIPLY_OVERFLOW (A, B)'
     Yield 1 if `A * B' would overflow.  See above for restrictions.

`INT_DIVIDE_OVERFLOW (A, B)'
     Yields 1 if `A / B' would overflow.  See above for restrictions.
     Division overflow can happen on two's complement hosts when
     dividing the most negative integer by -1.  This macro does not
     check for division by zero.

`INT_REMAINDER_OVERFLOW (A, B)'
     Yield 1 if `A % B' would overflow.  See above for restrictions.
     Remainder overflow can happen on two's complement hosts when
     dividing the most negative integer by -1; although the
     mathematical result is always 0, in practice some implementations
     trap, so this counts as an overflow.  This macro does not check for
     division by zero.

`INT_LEFT_SHIFT_OVERFLOW (A, B)'
     Yield 1 if `A << B' would overflow.  See above for restrictions.
     The C standard says that behavior is undefined for shifts unless
     0<=B<W where W is A's word width, and that when A is negative then
     `A << B' has undefined behavior and `A >> B' has
     implementation-defined behavior, but this macro does not check
     these other restrictions.

12.6 Character and String Functions in C Locale
===============================================

   The functions in this section are similar to the generic string
functions from the standard C library, except that
   * They behave as if the locale was set to the "C" locale, even when
     the locale is different, and/or

   * They are specially optimized for the case where all characters are
     plain ASCII characters.

File: gnulib.info,  Node: c-ctype,  Next: c-strcase,  Up: String Functions in C Locale

12.6.1 c-ctype
--------------

   The `c-ctype' module contains functions operating on single-byte
characters, like the functions in `<ctype.h>', that operate as if the
locale encoding was ASCII.  (The "C" locale on many systems has the
locale encoding "ASCII".)

   The functions are:
     extern bool c_isascii (int c);

     extern bool c_isalnum (int c);
     extern bool c_isalpha (int c);
     extern bool c_isblank (int c);
     extern bool c_iscntrl (int c);
     extern bool c_isdigit (int c);
     extern bool c_islower (int c);
     extern bool c_isgraph (int c);
     extern bool c_isprint (int c);
     extern bool c_ispunct (int c);
     extern bool c_isspace (int c);
     extern bool c_isupper (int c);
     extern bool c_isxdigit (int c);

     extern int c_tolower (int c);
     extern int c_toupper (int c);

   These functions assign properties only to ASCII characters.

   The C argument can be a `char' or `unsigned char' value, whereas the
corresponding functions in `<ctype.h>' take an argument that is
actually an `unsigned char' value.

   The `c_is*' functions return `bool', where the corresponding
functions in `<ctype.h>' return `int' for historical reasons.

   Note: The `<ctype.h>' functions support only unibyte locales.

12.6.2 c-strcase
----------------

   The `c-strcase' module contains case-insensitive string comparison
functions operating on single-byte character strings, like the
functions in `<strings.h>', that operate as if the locale encoding was
ASCII.  (The "C" locale on many systems has the locale encoding

   The functions are:
     extern int c_strcasecmp (const char *s1, const char *s2);
     extern int c_strncasecmp (const char *s1, const char *s2, size_t n);

   For case conversion here, only ASCII characters are considered to be
upper case or lower case.

   Note: The functions `strcasecmp', `strncasecmp' from `<strings.h>'
support only unibyte locales; for multibyte locales, you need the
functions `mbscasecmp', `mbsncasecmp', `mbspcasecmp'.

12.6.3 c-strcaseeq
------------------

   The `c-strcaseeq' module contains an optimized case-insensitive
string comparison function operating on single-byte character strings,
that operate as if the locale encoding was ASCII.  (The "C" locale on
many systems has the locale encoding "ASCII".)

   The functions is actually implemented as a macro:
     extern int STRCASEEQ (const char *s1, const char *s2,
                           int s20, int s21, int s22, int s23, int s24, int s25,
                           int s26, int s27, int s28);

   S2 should be a short literal ASCII string, and S20, S21, ...  the
individual characters of S2.

   For case conversion here, only ASCII characters are considered to be
upper case or lower case.

12.6.4 c-strcasestr
-------------------

   The `c-strcasestr' module contains a case-insensitive string search
function operating on single-byte character strings, that operate as if
the locale encoding was ASCII.  (The "C" locale on many systems has the
locale encoding "ASCII".)

   The function is:
     extern char *c_strcasestr (const char *haystack, const char *needle);

   For case conversion here, only ASCII characters are considered to be
upper case or lower case.

   Note: The function `strcasestr' from `<string.h>' supports only
unibyte locales; for multibyte locales, you need the function
`mbscasestr'.

---------------

   The `c-strstr' module contains a substring search function operating
on single-byte character strings, that operate as if the locale encoding
was ASCII.  (The "C" locale on many systems has the locale encoding
"ASCII".)

   The function is:
     extern char *c_strstr (const char *haystack, const char *needle);

   Note: The function `strstr' from `<string.h>' supports only unibyte
locales; for multibyte locales, you need the function `mbsstr'.

12.6.6 c-strtod
---------------

   The `c-strtod' module contains a string to number (`double')
conversion function operating on single-byte character strings, that
operates as if the locale encoding was ASCII.  (The "C" locale on many
systems has the locale encoding "ASCII".)

   The function is:
     extern double c_strtod (const char *string, char **endp);

   In particular, only a period `.' is accepted as decimal point, even
when the current locale's notion of decimal point is a comma `,', and
no characters outside the basic character set are accepted.

   On platforms without `strtod_l', this function is not safe for use in
multi-threaded applications since it calls `setlocale'.

   The `c-strtold' module contains a string to number (`long double')
conversion function operating on single-byte character strings, that
operates as if the locale encoding was ASCII.  (The "C" locale on many
systems has the locale encoding "ASCII".)

   The function is:
     extern long double c_strtold (const char *string, char **endp);

   In particular, only a period `.' is accepted as decimal point, even
when the current locale's notion of decimal point is a comma `,'.

12.7 Quoting
============

   Gnulib provides `quote' and `quotearg' modules to help with quoting
text, such as file names, in messages to the user.  Here's an example
of using `quote':

     #include <quote.h>
      ...
       error (0, errno, _("cannot change owner of %s"), quote (fname));

   This differs from

       error (0, errno, _("cannot change owner of '%s'"), fname);

in that `quote' escapes unusual characters in `fname', e.g., `'' and
control characters like `\n'.

   However, a caveat: `quote' reuses the storage that it returns.
Hence if you need more than one thing quoted at the same time, you need
to use `quote_n'.

   Also, the quote module is not suited for multithreaded applications.
In that case, you have to use `quotearg_alloc', defined in the
`quotearg' module, which is decidedly less convenient.

12.8 error and progname
=======================

   The `error' function uses the `program_name' variable, but does not
depend on the `progname' module.  Why?  Because `error' is released
under the LGPL, whereas `progname' is GPL.  RMS does not want
additional baggage accompanying the `error' module, so an LGPL user
must provide their own replacement `program_name', and a GPL user
should manually specify using the `progname' module.

   Additionally, using the `progname' module is not something that can
be done implicitly. It requires that every `main' function be modified
to set `program_name' as one of its first actions.


File: gnulib.info,  Node: gcd,  Next: Searching for Libraries,  Prev: error and progname,  Up: Particular Modules

12.9 gcd: greatest common divisor
=================================

   The `gcd' function returns the greatest common divisor of two numbers
`a > 0' and `b > 0'.  It is the caller's responsibility to ensure that
the arguments are non-zero.

   If you need a gcd function for an integer type larger than `unsigned
long', you can include the `gcd.c' implementation file with
parametrization.  The parameters are:

   * WORD_T Define this to the unsigned integer type that you need this
     function for.

   * GCD Define this to the name of the function to be created.

   The created function has the prototype
     WORD_T GCD (WORD_T a, WORD_T b);

   If you need the least common multiple of two numbers, it can be
computed like this: `lcm(a,b) = (a / gcd(a,b)) * b' or `lcm(a,b) = a *
(b / gcd(a,b))'.  Avoid the formula `lcm(a,b) = (a * b) / gcd(a,b)'
because - although mathematically correct - it can yield a wrong
result, due to integer overflow.

   In some applications it is useful to have a function taking the gcd
of two signed numbers. In this case, the gcd function result is usually
normalized to be non-negative (so that two gcd results can be compared
in magnitude or compared against 1, etc.). Note that in this case the
prototype of the function has to be
     unsigned long gcd (long a, long b);
   and not
     long gcd (long a, long b);
   because `gcd(LONG_MIN,LONG_MIN) = -LONG_MIN = LONG_MAX + 1' does not
fit into a signed `long'.

12.10 Searching for Libraries
=============================

   The following macros check for the presence or location of certain
C, C++, or Fortran library archive files.

Simple Library Tests
--------------------

   The macros `AC_CHECK_LIB', `AC_SEARCH_LIBS' from GNU Autoconf check
for the presence of certain C, C++, or Fortran library archive files.
The libraries are looked up in the default linker path - a system
dependent list of directories, that usually contains the `/usr/lib'
directory -  and those directories given by `-L' options in the
`LDFLAGS' variable.

Locating Libraries
------------------

   The following macros, defined in the Gnulib module `havelib', search
for the location of certain C, C++, or Fortran library archive files
and make the found location available to the compilation process and to
further Autoconf tests.

 -- Macro: `AC_LIB_LINKFLAGS(NAME, [DEPENDENCIES])'
     Searches for `lib<NAME>' and the libraries corresponding to
     explicit and implicit dependencies.  Sets and AC_SUBSTs the
     `LIB<NAME>' and `LTLIB<NAME>' variables (with `<NAME>' in upper
     case) and augments the `CPPFLAGS' variable by `-I' options.

     This macro should be used when `lib<NAME>' is expected to be found.

 -- Macro: `AC_LIB_HAVE_LINKFLAGS(NAME, [DEPENDENCIES], [INCLUDES],
[TESTCODE], [MISSING-MESSAGE])'
     Searches for `lib<NAME>' and the libraries corresponding to
     explicit and implicit dependencies, together with the specified
     include files and the ability to compile and link the specified
     TESTCODE.  The MISSING-MESSAGE defaults to `no' and may contain
     additional hints for the user.  If found, it sets and AC_SUBSTs
     `HAVE_LIB<NAME>=yes' and the `LIB<NAME>' and `LTLIB<NAME>'
     variables (with `<NAME>' in upper case) and augments the
     `CPPFLAGS' variable by `-I' options, and #defines `HAVE_LIB<NAME>'
     to 1.  Otherwise, it sets and AC_SUBSTs `HAVE_LIB<NAME>=no' and
     `LIB<NAME>' and `LTLIB<NAME>' to empty.

   These macros assume that when a library is installed in
`SOME_DIRECTORY/lib', its include files are installed in
`SOME_DIRECTORY/include'.

   The complexities that `AC_LIB_LINKFLAGS' and `AC_LIB_HAVE_LINKFLAGS'
deal with are the following:

   * The library is not necessarily already in the search path
     (`CPPFLAGS' for the include file search path, `LDFLAGS' for the
     library search path).  The macro provides a `--with-lib<NAME>'
     option.  The user of the `configure' script can use this option to
     indicate the location of the library and its include files.  If
     not provided, the `--prefix' directory is searched as well.

   * The library is not necessarily already in the run time library
     search path.  To avoid the need for setting an environment
     variable like `LD_LIBRARY_PATH', the macro adds the appropriate
     run time search path options to the `LIB<NAME>' variable.  This
     works on most systems.  It can also be inhibited: The user of
     `configure' can use the `--disable-rpath' option to force an
     installation that doesn't contain hardcoded library search paths
     but instead may require the use of an environment variable like
     `LD_LIBRARY_PATH'.

   The macros also set a variable `LTLIB<NAME>', that should be used
when linking with libtool.  Both `LTLIB<NAME>' and `LIB<NAME>' contain
essentially the same option, but where `LIB<NAME>' contains platform
dependent flags like `-Wl,-rpath', `LTLIB<NAME>' contains platform
independent flags like `-R'.

Example of using `AC_LIB_LINKFLAGS'
...................................

   Suppose you want to use `libz', the compression library.

  1. In configure.ac you add the line

            AC_CONFIG_AUX_DIR([build-aux])
            AC_LIB_LINKFLAGS([z])

     Note that since the `AC_LIB_LINKFLAGS' invocation modifies the
     CPPFLAGS, it should precede all tests that check for header files,
     declarations, structures or types.

  2. To the package's `build-aux' directory you add the file
     `config.rpath', also part of the Gnulib `havelib' module.
     (`gnulib-tool' will usually do this for you automatically.)

  3. In `Makefile.in' you add `@LIBZ@' to the link command line of your
     program.  Or, if you are using Automake, you add `$(LIBZ)' to the
     `LDADD' variable that corresponds to your program.

Dependencies
............

   The dependencies list is a space separated list of library names that
`libNAME' is known to depend upon.  Example: If `libfooy' depends on
`libfoox', and `libfooz' depends on `libfoox' and `libfooy', you can
write:

     AC_LIB_LINKFLAGS([foox])
     AC_LIB_LINKFLAGS([fooy], [foox])
     AC_LIB_LINKFLAGS([fooz], [foox fooy])

Explicit dependencies are necessary if you cannot assume that a `.la'
file, created by libtool, is installed.  If you can assume that
`libfooy.la' is installed by libtool (and has not been omitted by the
package distributor!), you can omit the explicit dependency and just
write

     AC_LIB_LINKFLAGS([fooy])

This way, you don't need to know in advance which libraries the needed
library depends upon.

Static vs. shared
.................

   The macros find the libraries regardless whether they are installed
as shared or static libraries.

`CPPFLAGS' vs. `LDFLAGS'
........................

   The macros determine the directories that should be added to the
compiler preprocessor's search path and to the linker's search path.
For the compiler preprocessor, `-I' options with the necessary
directories are added to the `CPPFLAGS' variable, for use by the whole
package.  For the linker, appropriate options are added to the
`LIB<NAME>' and `LTLIB<NAME>' variables, for use during linking by
those programs and libraries that need the dependency on `lib<NAME>'.
You need to use the value of `LIB<NAME>' or `LTLIB<NAME>' in the
Makefiles.  `LTLIB<NAME>' is for use with libtool, whereas `LIB<NAME>'
is for when libtool is not involved in linking.

   The macros do not check whether the include files and the library
found match.  If you want to verify this at configure time, one
technique is to have a version number in the include files and a
version number in the library, like this:
       #define LIBNAME_VERSION 10203
       extern int libNAME_version; /* initialized to LIBNAME_VERSION */
   and use a test like
       AC_TRY_RUN([int main () { return libNAME_version != LIBNAME_VERSION; }])

Bi-arch systems
...............

   A bi-arch system is one where
   * the processor has a 32-bit execution mode and a 64-bit execution
     mode (for example, x86_64, ia64, sparc64, powerpc64), and

   * 32-bit mode libraries and executables and 64-bit mode libraries
     are both installed, and

   * 32-bit mode libraries and object files cannot be mixed with 64-bit
     mode ones.

   On several types of such systems, for historical reasons, the 32-bit
libraries are installed in `PREFIX/lib', whereas the 64-bit libraries
are installed in
   * `PREFIX/lib64' on many glibc systems,

   * `PREFIX/lib/64' on Solaris systems.

   On such systems, in 64-bit mode, `configure' will search for the
libraries in `PREFIX/lib64' or `PREFIX/lib/64', respectively, not in
`PREFIX/lib'.  A user can adhere to these system-wide conventions by
using the `--libdir' option when installing packages.  When a user has
already installed packages in 64-bit mode using the GNU default
`--libdir=PREFIX/lib', he can make this directory adhere to the
system-wide convention by placing a symbolic link:
On glibc systems:
     `ln -s lib PREFIX/lib64'

On Solaris systems:
     `ln -s . PREFIX/lib/64'


File: gnulib.info,  Node: Exported Symbols of Shared Libraries,  Next: LD Version Scripts,  Prev: Searching for Libraries,  Up: Particular Modules

12.11 Controlling the Exported Symbols of Shared Libraries
==========================================================

   The `lib-symbol-visibility' module allows precise control of the
symbols exported by a shared library.  This is useful because

   * It prevents abuse of undocumented APIs of your library.  Symbols
     that are not exported from the library cannot be used.  This
     eliminates the problem that when the maintainer of the library
     changes internals of the library, maintainers of other projects
     cry "breakage".  Instead, these maintainers are forced to
     negotiate the desired API from the maintainer of the library.

   * It reduces the risk of symbol collision between your library and
     other libraries.  For example, the symbol `readline' is defined in
     several libraries, most of which don't have the same semantics and
     the same calling convention as the GNU readline library.

   * It reduces the startup time of programs linked to the library.
     This is because the dynamic loader has less symbols to process.

   * It allows the compiler to generate better code.  Within a shared
     library, a call to a function that is a global symbol costs a
     "call" instruction to a code location in the so-called PLT
     (procedure linkage table) which contains a "jump" instruction to
     the actual function's code.  (This is needed so that the function
     can be overridden, for example by a function with the same name in
     the executable or in a shared library interposed with
     `LD_PRELOAD'.) Whereas a call to a function for which the compiler
     can assume that it is in the same shared library is just a direct
     "call" instructions.  Similarly for variables: A reference to a
     global variable fetches a pointer in the so-called GOT (global
     offset table); this is a pointer to the variable's memory.  So the
     code to access it is two memory load instructions.  Whereas for a
     variable which is known to reside in the same shared library, it
     is just a direct memory access: one memory load instruction.

   There are traditionally three ways to specify the exported symbols
of a shared library.

   * The programmer specifies the list of symbols to be exported when
     the shared library is created.  Usually a command-line option is
     passed to the linker, with the name of a file containing the
     symbols.

     The upside of this approach is flexibility: it allows the same
     code to be used in different libraries with different export
     lists.  The downsides are: 1. it's a lot of maintenance overhead
     when the symbol list is platform dependent, 2. it doesn't work
     well with C++, due to name mangling.

   * The programmer specifies a "hidden" attribute for every variable
     and function that shall not be exported.

     The drawbacks of this approach are: Symbols are still exported from
     the library by default.  It's a lot of maintenance work to mark
     every non- exported variable and function.  But usually the
     exported API is quite small, compared to the internal API of the
     library.  And it's the wrong paradigm: It doesn't force thinking
     when introducing new exported API.

   * The programmer specifies a "hidden" attribute for all files that
     make up the shared library, and an "exported" attribute for those
     symbols in these files that shall be exported.

     This is perfect: It burdens the maintainer only for exported API,
     not for library-internal API.  And it keeps the annotations in the
     source code.

   GNU libtool's `-export-symbols' option implements the first approach.

   This gnulib module implements the third approach.  For this it
relies on GNU GCC 4.0 or newer, namely on its `-fvisibility=hidden'
command-line option and the "visibility" attribute.  (The "visibility"
attribute was already supported in GCC 3.4, but without the command
line option, introduced in GCC 4.0, the third approach could not be
used.)

   More explanations on this subject can be found in
`http://gcc.gnu.org/wiki/Visibility' - which contains more details on
the GCC features and additional advice for C++ libraries - and in
Ulrich Drepper's paper `http://people.redhat.com/drepper/dsohowto.pdf'
- which also explains other tricks for reducing the startup time impact
of shared libraries.

   The gnulib autoconf macro `gl_VISIBILITY' tests for GCC 4.0 or newer.
It defines a Makefile variable `@CFLAG_VISIBILITY@' containing
`-fvisibility=hidden' or nothing.  It also defines as a C macro and as
a substituted variable: @HAVE_VISIBILITY@.  Its value is 1 when symbol
visibility control is supported, and 0 otherwise.

   To use this module in a library, say libfoo, you will do these steps:

  1. Add `@CFLAG_VISIBILITY@' or (in a Makefile.am)
     `$(CFLAG_VISIBILITY)' to the CFLAGS for the compilation of the
     sources that make up the library.

  2. Add a C macro definition, say `-DBUILDING_LIBFOO', to the CPPFLAGS
     for the compilation of the sources that make up the library.

  3. Define a macro specific to your library like this.
          #if BUILDING_LIBFOO && HAVE_VISIBILITY
          #define LIBFOO_DLL_EXPORTED __attribute__((__visibility__("default")))
          #else
          #define LIBFOO_DLL_EXPORTED
          #endif
     This macro should be enabled in all public header files of your
     library.

  4. Annotate all variable, function and class declarations in all
     public header files of your library with `LIBFOO_DLL_EXPORTED'.
     This annotation can occur at different locations: between the
     `extern' and the type or return type, or just before the entity
     being declared, or after the entire declarator.  My preference is
     to put it right after `extern', so that the declarations in the
     header files remain halfway readable.

   Note that the precise control of the exported symbols will not work
with other compilers than GCC >= 4.0, and will not work on systems
where the assembler or linker lack the support of "hidden" visibility.
Therefore, it's good if, in order to reduce the risk of collisions with
symbols in other libraries, you continue to use a prefix specific to
your library for all non-static variables and functions and for all C++
classes in your library.

   Note about other compilers: MSVC support can be added easily, by
extending the definition of the macro mentioned above, to something
like this:
     #if BUILDING_LIBFOO && HAVE_VISIBILITY
     #define LIBFOO_DLL_EXPORTED __attribute__((__visibility__("default")))
     #elif BUILDING_LIBFOO && defined _MSC_VER
     #define LIBFOO_DLL_EXPORTED __declspec(dllexport)
     #elif defined _MSC_VER
     #define LIBFOO_DLL_EXPORTED __declspec(dllimport)
     #else
     #define LIBFOO_DLL_EXPORTED
     #endif


File: gnulib.info,  Node: LD Version Scripts,  Next: Visual Studio Compatibility,  Prev: Exported Symbols of Shared Libraries,  Up: Particular Modules

12.12 LD Version Scripts
========================

   The `lib-symbol-versions' module can be used to add shared library
versioning support.  Currently, only GNU LD and the Solaris linker
supports this.

   Version scripts provides information that can be used by GNU/Linux
distribution packaging tools.  For example, Debian has a tool
`dpkg-shlibdeps' that can determine the minimal required version of
each dependency (by looking at the symbol list) and stuff the
information into the Debian specific packaging files.

   For more information and other uses of version scripts, see Ulrich
Drepper's paper `http://people.redhat.com/drepper/dsohowto.pdf'

   You use the module by importing it to your library, and then add the
following lines to the `Makefile.am' that builds the library:

     if HAVE_LD_VERSION_SCRIPT
     libfoo_la_LDFLAGS += -Wl,--version-script=$(srcdir)/libfoo.map
     endif

   The version script file format is documented in the GNU LD manual,
but a small example would be:

     LIBFOO_1.0 {
       global:
         libfoo_init; libfoo_doit; libfoo_done;

       local:
         *;
     };

   If you target platforms that do not support linker scripts (i.e., all
platforms that doesn't use GNU LD) you may want to consider a more
portable but less powerful alternative: libtool `-export-symbols'.  It
will hide internal symbols from your library, but will not add ELF
versioning symbols.  Your usage would then be something like:

     if HAVE_LD_VERSION_SCRIPT
     libfoo_la_LDFLAGS += -Wl,--version-script=$(srcdir)/libfoo.map
     else
     libfoo_la_LDFLAGS += -export-symbols $(srcdir)/libfoo.sym
     endif

   See the Libtool manual for the file syntax, but a small example would
be:

     libfoo_init
     libfoo_doit
     libfoo_done

   To avoid the need for a `*.sym' file if your symbols are easily
expressed using a regular expression, you may use
`-export-symbols-regex':

     if HAVE_LD_VERSION_SCRIPT
     libfoo_la_LDFLAGS += -Wl,--version-script=$(srcdir)/libfoo.map
     else
     libfoo_la_LDFLAGS += -export-symbols-regex '^libfoo_.*'
     endif

   For more discussions about symbol visibility, rather than shared
library versioning, see the `visibility' module (*note Exported Symbols
of Shared Libraries::).


File: gnulib.info,  Node: Visual Studio Compatibility,  Next: Supporting Relocation,  Prev: LD Version Scripts,  Up: Particular Modules

12.13 Visual Studio Compatibility
=================================

   The `lib-msvc-compat' module detects whether the linker supports
`--output-def' when building a library.  That parameter is used to
generate a DEF file for a shared library (DLL).  DEF files are useful
for developers that use Visual Studio to develop programs that links to
your library.  See the GNU LD manual for more information.

   There are other ways to create a DEF file, but we believe they are
all sub-optimal to using `--output-def' during the build process.  The
variants we have considered include:

   * Use DUMPBIN /EXPORTS.  This is explained in
     `http://support.microsoft.com/kb/131313/en-us'.  The tool does not
     generate DEF files directly, so its output needs to be post
     processed manually:
          $ { echo EXPORTS; \
              dumpbin /EXPORTS libfoo-0.dll | tail -n+20 | awk '{ print $4 }'; \
            } > libfoo-0.def
          $ lib /def:libfoo-0.def

   * Use IMPDEF.  There is a tool called IMPDEF
     (`http://sei.pku.edu.cn/~caodg/course/c/reference/win32/tools/dlltool.html')
     that can generate DEF files.  However, it is not part of a standard
     Visual Studio installation.  Further, it is documented as being an
     unreliable process.

   * Use DLLTOOL.  The dlltool is part of the MinGW suite, and thus not
     part of a standard Visual Studio installation.  The documentation
     for the IMPDEF tool claims that DLLTOOL is the wrong tool for this
     job.  Finally, DLLTOOL does not generate DEF files directly, so it
     requires post-processing of the output.


   If you are using libtool to build your shared library, here is how to
use this module.  Import `lib-msvc-compat' to your project, and then
add the following lines to the `Makefile.am' that builds the library:

     if HAVE_LD_OUTPUT_DEF
     libfoo_la_LDFLAGS += -Wl,--output-def,libfoo-$(DLL_VERSION).def
     defexecdir = $(bindir)
     defexec_DATA = libfoo-$(DLL_VERSION).def
     DISTCLEANFILES += $(defexec_DATA)
     endif

   The `DLL_VERSION' variable needs to be defined.  It should be the
shared library version number used in the DLL filename.  For Windows
targets you compute this value from the values you pass to Libtool's
`-version-info'.  Assuming you have variables `LT_CURRENT' and `LT_AGE'
defined for the `CURRENT' and `AGE' libtool version integers, you
compute `DLL_VERSION' as follows:

     DLL_VERSION=`expr ${LT_CURRENT} - ${LT_AGE}`
     AC_SUBST(DLL_VERSION)

12.14 Supporting Relocation
===========================

   It has been a pain for many users of GNU packages for a long time
that packages are not relocatable.  It means a user cannot copy a
program, installed by another user on the same machine, to his home
directory, and have it work correctly (including i18n).  So many users
need to go through `configure; make; make install' with all its
dependencies, options, and hurdles.

   Red Hat, Debian, and similar package systems solve the "ease of
installation" problem, but they hardwire path names, usually to `/usr'
or `/usr/local'.  This means that users need root privileges to install
a binary package, and prevents installing two different versions of the
same binary package.

   A relocatable program can be moved or copied to a different location
on the file system.  It is possible to make symlinks to the installed
and moved programs, and invoke them through the symlink. It is possible
to do the same thing with a hard link _only_ if the hard link file is
in the same directory as the real program.

   The `relocatable-prog' module aims to ease the process of making a
GNU program relocatable.  It helps overcome two obstacles.  First, it
aids with relocating the hard-coded references to absolute file names
that GNU programs often contain.  These references must be fixed up at
runtime if a program is to be successfully relocated.  The
`relocatable-prog' module provides a function `relocate' that does this
job.

   Second, the loader must be able to find shared libraries linked to
relocatable executables or referenced by other shared libraries linked
to relocatable executables.  The `relocatable-prog' module helps out
here in a platform-specific way:

   * On GNU/Linux, it adds a linker option (`-rpath') that causes the
     dynamic linker to search for libraries in a directory relative to
     the location of the invoked executable.

   * On other Unix systems, it installs a wrapper executable.  The
     wrapper sets the environment variable that controls shared library
     searching (usually `LD_LIBRARY_PATH') and then invokes the real
     executable.

     This approach does not always work.  On OpenBSD and OpenServer,
     prereleases of Libtool 1.5 put absolute file names of libraries in
     executables, which prevents searching any other locations.

   * On Windows, the executable's own directory is searched for
     libraries, so installing shared libraries into the executable's
     directory is sufficient.

   You can make your program relocatable by following these steps:

  1. Import the `relocatable-prog' module.

  2. In every program, add to `main' as the first statement (even
     before setting the locale or doing anything related to libintl):

          set_program_name (argv[0]);

     The prototype for this function is in `progname.h'.

  3. Everywhere where you use a constant pathname from
     installation-time, wrap it in `relocate' so it gets translated to
     the run-time situation.  Example:

          bindtextdomain (PACKAGE, LOCALEDIR);

     becomes:

          bindtextdomain (PACKAGE, relocate (LOCALEDIR));

     The prototype for this function is in `relocatable.h'.

  4. The `set_program_name' function can also configure some additional
     libraries to relocate files that they access, by defining
     corresponding C preprocessor symbols to 1.  The libraries for which
     this is supported and the corresponding preprocessor symbols are:

    libcharset
          `DEPENDS_ON_LIBCHARSET'

    libiconv
          `DEPENDS_ON_LIBICONV'

    libintl
          `DEPENDS_ON_LIBINTL'

     Defining the symbol for a library makes every program in the
     package depend on that library, whether the program really uses
     the library or not, so this feature should be used with some
     caution.

  5. If your package installs shell scripts, also import the
     `relocatable-script' module.  Then, near the beginning of each
     shell script that your package installs, add the following:

          @relocatable_sh@
          if test "@RELOCATABLE@" = yes; then
            exec_prefix="@exec_prefix@"
            bindir="@bindir@"
            orig_installdir="$bindir" # see Makefile.am's *_SCRIPTS variables
            func_find_curr_installdir # determine curr_installdir
            func_find_prefixes
            # Relocate the directory variables that we use.
            gettext_dir=`
              echo "$gettext_dir/" \
              | sed -e "s%^${orig_installprefix}/%${curr_installprefix}/%" \
              | sed -e 's,/$,,'`
          fi

     You must adapt the definition of `orig_installdir', depending on
     where the script gets installed.  Also, at the end, instead of
     `gettext_dir', transform those variables that you need.

  6. In your `Makefile.am', for every program `foo' that gets installed
     in, say, `$(bindir)', you add:

          foo_CPPFLAGS = -DINSTALLDIR=\"$(bindir)\"
          if RELOCATABLE_VIA_LD
          foo_LDFLAGS = `$(RELOCATABLE_LDFLAGS) $(bindir)`
          endif

  7. You may also need to add a couple of variable assignments to your
     `configure.ac'.

     If your package (or any package you rely on, e.g. gettext-runtime)
     will be relocated together with a set of installed shared
     libraries, then set RELOCATABLE_LIBRARY_PATH to a colon-separated
     list of those libraries' directories, e.g.
          RELOCATABLE_LIBRARY_PATH='$(libdir)'

     If your `config.h' is not in `$(top_builddir)', then set
     RELOCATABLE_CONFIG_H_DIR to its directory, e.g.
          RELOCATABLE_CONFIG_H_DIR='$(top_builddir)/src'

12.15 func
==========

   The `func' module makes sure that you can use the predefined
identifier `__func__' as defined by C99 in your code.

   A small example is:

     #include <config.h>
     #include <stdio.h> /* for printf */

     int main (void)
     {
         printf ("%s: hello world\n", __func__);
     }

   Note that `sizeof' cannot be applied to `__func__': On SunPRO C
compiler, `sizeof __func__' evaluates to 0.


File: gnulib.info,  Node: configmake,  Next: warnings,  Prev: func,  Up: Particular Modules

12.16 configmake
================

   The `configmake' module builds a C include file named `configmake.h'
containing the usual installation directory values; for example, those
specified by `--prefix' or `--libdir' to configure.  Each variable is
given a `#define' with an all-uppercase macro name, such as `PREFIX' and
`LIBDIR'.  (Automake cannot create this file directly because the user
might override directory values at `make' time.)

   Specifically, the module retrieves values of the variables through
`configure' followed by `make', not directly through `configure', so
that a user who sets some of these variables consistently on the `make'
command line gets correct results.

   One advantage of this approach, compared to the classical approach of
adding `-DLIBDIR=\"$(libdir)\"' etc. to `AM_CPPFLAGS', is that it
protects against the use of undefined variables.  That is, if, say,
`$(libdir)' is not set in the Makefile, `LIBDIR' is not defined by this
module, and code using `LIBDIR' gives a compilation error.

   Another advantage is that `make' output is shorter.

   For the complete list of variables which are `#define'd this way,
see the file `gnulib/modules/configmake', or inspect your resulting
gnulib Makefile.


File: gnulib.info,  Node: warnings,  Next: manywarnings,  Prev: configmake,  Up: Particular Modules

12.17 warnings
==============

   The `warnings' module allows to regularly build a package with more
GCC warnings than the default warnings emitted by GCC.

   It provides the following functionality:

   * You can select some warning options, such as `-Wall', to be enabled
     whenever building with a GCC version that supports these options.
     The user can choose to override these warning options by providing
     the opposite options in the `CFLAGS' variable at configuration
     time.

   * You can make these warnings apply to selected directories only.  In
     projects where subprojects are maintained by different people, or
     where parts of the source code are imported from external sources
     - for example from gnulib -, it is useful to apply different
     warning options to different directories.

   * It allows to use `-Werror' at `make distcheck' time, to verify
     that on the maintainer's system, no warnings remain.  (Note that
     use of `-Werror' in `CFLAGS' does not work in general, because it
     may break autoconfiguration.)

   To use this module, you need the following:

  1. In `configure.ac', use for example
          gl_WARN_ADD([-Wall], [WARN_CFLAGS])
          gl_WARN_ADD([-Wpointer-arith], [WARN_CFLAGS])

  2. In the directories which shall use `WARN_CFLAGS', use it in the
     definition of `AM_CFLAGS', like this:
          AM_CFLAGS = $(WARN_CFLAGS)

     Note that the `AM_CFLAGS' is used in combination with `CFLAGS' and
     before `CFLAGS' in build rules emitted by Automake.  This allows
     the user to provide `CFLAGS' that override the `WARN_CFLAGS'.

   Note that it is a bad idea to use `gl_WARN_ADD([-Werror])'.  The
warnings emitted by GCC depend, to some extent, on the contents of the
system header files, on the size and signedness of built-in types, etc.
Use of `-Werror' would cause frustration to all users on platforms that
the maintainer has not tested before the release.  It is better if
maintainers use `-Werror' only for themselves (for example, during
`make distcheck', as mentioned above).


File: gnulib.info,  Node: manywarnings,  Next: Running self-tests under valgrind,  Prev: warnings,  Up: Particular Modules

12.18 manywarnings
==================

   The `manywarnings' module allows you to enable as many GCC warnings
as possible for your package. The purpose is to protect against
introducing new code that triggers warnings that weren't already
triggered by the existing code base.

   An example use of the module is as follows:

     gl_MANYWARN_ALL_GCC([warnings])
     # Set up the list of the pointless, undesired warnings.
     nw=
     nw="$nw -Wsystem-headers"       # Don't let system headers trigger warnings
     nw="$nw -Wundef"                # All compiler preprocessors support #if UNDEF
     nw="$nw -Wtraditional"          # All compilers nowadays support ANSI C
     nw="$nw -Wconversion"           # These warnings usually don't point to mistakes.
     nw="$nw -Wsign-conversion"      # Likewise.
     # Enable all GCC warnings not in this list.
     gl_MANYWARN_COMPLEMENT([warnings], [$warnings], [$nw])
     for w in $warnings; do
       gl_WARN_ADD([$w])
     done

   This module is meant to be used by developers who are not very
experienced regarding the various GCC warning options. In the beginning
you will set the list of undesired warnings (`nw' in the example above)
to empty, and compile the package with all possible warnings enabled.
The GCC option `-fdiagnostics-show-option', available in GCC 4.1 or
newer, helps understanding which warnings originated from which option.
Then you will go through the list of warnings. You will likely
deactivate warnings that occur often and don't point to mistakes in the
code, by adding them to the `nw' variable, then reconfiguring and
recompiling. When warnings point to real mistakes and bugs in the code,
you will of course not disable them.

   There are also many GCC warning options which usually don't point to
mistakes in the code; these warnings enforce a certain programming
style. It is a project management decision whether you want your code
to follow any of these styles. Note that some of these programming
styles are conflicting. You cannot have them all; you have to choose
among them.

   When a new version of GCC is released, you can add the new warning
options that it introduces into the `gl_MANYWARN_ALL_GCC' macro (and
submit your modification to the Gnulib maintainers :-)), and enjoy the
benefits of the new warnings, while adding the undesired ones to the
`nw' variable.


File: gnulib.info,  Node: Running self-tests under valgrind,  Next: stat-size,  Prev: manywarnings,  Up: Particular Modules

12.19 Running self-tests under valgrind
=======================================

   For projects written in C or similar languages, running the
self-tests under Valgrind can reveal hard to find memory issues.  The
`valgrind-tests' module searches for Valgrind and declares the
`VALGRIND' automake variable for use with automake's
`TESTS_ENVIRONMENT'.

   After importing the `valgrind-tests' module to your project, you use
it by adding the following to the `Makefile.am' that runs the
self-tests:

     TESTS_ENVIRONMENT = $(VALGRIND)

   This will run all self-checks under valgrind.  This can be wasteful
if you have many shell scripts or other non-binaries.  Using the
Automake parallel-tests feature, this can be avoided by using the
following instead:

     AUTOMAKE_OPTIONS = parallel-tests
     TEST_EXTENSIONS = .pl .sh
     LOG_COMPILER = $(VALGRIND)

   Then valgrind will only be used for the non-.sh and non-.pl tests.
However, this means that binaries invoked through scripts will not be
invoked under valgrind, which could be solved by adding the following:

     TESTS_ENVIRONMENT = VALGRIND='$(VALGRIND)'

   And then modify the shell scripts to invoke the binary prefixed with
`$VALGRIND'.


File: gnulib.info,  Node: stat-size,  Prev: Running self-tests under valgrind,  Up: Particular Modules

12.20 stat-size
===============

   The `stat-size' module provides a small number of macros intended
for interpreting the file size information in an instance of `struct
stat'.

   On POSIX systems, the `st_blocks' member of `struct stat' contains
the number of disk blocks occupied by a file.  The `ST_NBLOCKS' macro
is used to estimate this quantity on systems which don't actually have
`st_blocks'.  Each of these blocks contains `ST_NBLOCKSIZE' bytes.

   The value of `ST_NBLOCKSIZE' is often quite small, small enough that
performing I/O in chunks that size would be inefficient.  `ST_BLKSIZE'
is the I/O block size recommended for I/O to this file.  This is not
guaranteed to give optimum performance, but it should be reasonably
efficient.

File: gnulib.info,  Node: Overview,  Next: Regular Expression Syntax,  Up: Regular expressions

13.1 Overview
=============

   A "regular expression" (or "regexp", or "pattern") is a text string
that describes some (mathematical) set of strings.  A regexp R
"matches" a string S if S is in the set of strings described by R.

   Using the Regex library, you can:

   * see if a string matches a specified pattern as a whole, and

   * search within a string for a substring matching a specified
     pattern.


   Some regular expressions match only one string, i.e., the set they
describe has only one member.  For example, the regular expression
`foo' matches the string `foo' and no others.  Other regular
expressions match more than one string, i.e., the set they describe has
more than one member.  For example, the regular expression `f*' matches
the set of strings made up of any number (including zero) of `f's.  As
you can see, some characters in regular expressions match themselves
(such as `f') and some don't (such as `*'); the ones that don't match
themselves instead let you specify patterns that describe many
different strings.

   To either match or search for a regular expression with the Regex
library functions, you must first compile it with a Regex pattern
compiling function.  A "compiled pattern" is a regular expression
converted to the internal format used by the library functions.  Once
you've compiled a pattern, you can use it for matching or searching any
number of times.

   The Regex library is used by including `regex.h'.  Regex provides
three groups of functions with which you can operate on regular
expressions.  One group--the GNU group--is more powerful but not
completely compatible with the other two, namely the POSIX and Berkeley
UNIX groups; its interface was designed specifically for GNU.

   We wrote this chapter with programmers in mind, not users of
programs--such as Emacs--that use Regex.  We describe the Regex library
in its entirety, not how to write regular expressions that a particular
program understands.


File: gnulib.info,  Node: Regular Expression Syntax,  Next: Common Operators,  Prev: Overview,  Up: Regular expressions

13.2 Regular Expression Syntax
==============================

   "Characters" are things you can type.  "Operators" are things in a
regular expression that match one or more characters.  You compose
regular expressions from operators, which in turn you specify using one
or more characters.

   Most characters represent what we call the match-self operator, i.e.,
they match themselves; we call these characters "ordinary".  Other
characters represent either all or parts of fancier operators; e.g.,
`.' represents what we call the match-any-character operator (which, no
surprise, matches (almost) any character); we call these characters
"special".  Two different things determine what characters represent
what operators:

  1. the regular expression syntax your program has told the Regex
     library to recognize, and

  2. the context of the character in the regular expression.

   In the following sections, we describe these things in more detail.

* Predefined Syntaxes::
* Collating Elements vs. Characters::
* The Backslash Character::


File: gnulib.info,  Node: Syntax Bits,  Next: Predefined Syntaxes,  Up: Regular Expression Syntax

13.2.1 Syntax Bits
------------------

   In any particular syntax for regular expressions, some characters are
always special, others are sometimes special, and others are never
special.  The particular syntax that Regex recognizes for a given
regular expression depends on the current syntax (as set by
`re_set_syntax') when the pattern buffer of that regular expression was
compiled.

   You get a pattern buffer by compiling a regular expression.  *Note
GNU Pattern Buffers::, for more information on pattern buffers.  *Note
GNU Regular Expression Compiling::, and *note BSD Regular Expression
Compiling::, for more information on compiling.

   Regex considers the current syntax to be a collection of bits; we
refer to these bits as "syntax bits".  In most cases, they affect what
characters represent what operators.  We describe the meanings of the
operators to which we refer in *note Common Operators::, *note GNU
Operators::, and *note GNU Emacs Operators::.

   For reference, here is the complete list of syntax bits, in
alphabetical order:

`RE_BACKSLASH_ESCAPE_IN_LISTS'
     If this bit is set, then `\' inside a list (*note List Operators::
     quotes (makes ordinary, if it's special) the following character;
     if this bit isn't set, then `\' is an ordinary character inside
     lists.  (*Note The Backslash Character::, for what `\' does
     outside of lists.)

`RE_BK_PLUS_QM'
     If this bit is set, then `\+' represents the match-one-or-more
     operator and `\?' represents the match-zero-or-more operator; if
     this bit isn't set, then `+' represents the match-one-or-more
     operator and `?' represents the match-zero-or-one operator.  This
     bit is irrelevant if `RE_LIMITED_OPS' is set.

`RE_CHAR_CLASSES'
     If this bit is set, then you can use character classes in lists;
     if this bit isn't set, then you can't.

`RE_CONTEXT_INDEP_ANCHORS'
     If this bit is set, then `^' and `$' are special anywhere outside
     a list; if this bit isn't set, then these characters are special
     only in certain contexts.  *Note Match-beginning-of-line
     Operator::, and *note Match-end-of-line Operator::.

`RE_CONTEXT_INDEP_OPS'
     If this bit is set, then certain characters are special anywhere
     outside a list; if this bit isn't set, then those characters are
     special only in some contexts and are ordinary elsewhere.
     Specifically, if this bit isn't set then `*', and (if the syntax
     bit `RE_LIMITED_OPS' isn't set) `+' and `?' (or `\+' and `\?',
     depending on the syntax bit `RE_BK_PLUS_QM') represent repetition
     operators only if they're not first in a regular expression or
     just after an open-group or alternation operator.  The same holds
     for `{' (or `\{', depending on the syntax bit `RE_NO_BK_BRACES') if
     it is the beginning of a valid interval and the syntax bit
     `RE_INTERVALS' is set.

`RE_CONTEXT_INVALID_DUP'
     If this bit is set, then an open-interval operator cannot occur at
     the start of a regular expression, or immediately after an
     alternation, open-group or close-interval operator.

`RE_CONTEXT_INVALID_OPS'
     If this bit is set, then repetition and alternation operators
     can't be in certain positions within a regular expression.
     Specifically, the regular expression is invalid if it has:

        * a repetition operator first in the regular expression or just
          after a match-beginning-of-line, open-group, or alternation
          operator; or

        * an alternation operator first or last in the regular
          expression, just before a match-end-of-line operator, or just
          after an alternation or open-group operator.


     If this bit isn't set, then you can put the characters
     representing the repetition and alternation characters anywhere in
     a regular expression.  Whether or not they will in fact be
     operators in certain positions depends on other syntax bits.

`RE_DEBUG'
     If this bit is set, and the regex library was compiled with
     `-DDEBUG', then internal debugging is turned on; if unset, then it
     is turned off.

`RE_DOT_NEWLINE'
     If this bit is set, then the match-any-character operator matches
     a newline; if this bit isn't set, then it doesn't.

`RE_DOT_NOT_NULL'
     If this bit is set, then the match-any-character operator doesn't
     match a null character; if this bit isn't set, then it does.

`RE_HAT_LISTS_NOT_NEWLINE'
     If this bit is set, nonmatching lists `[^...]' do not match
     newline; if not set, they do.

`RE_ICASE'
     If this bit is set, then ignore case when matching; otherwise,
     case is significant.

`RE_INTERVALS'
     If this bit is set, then Regex recognizes interval operators; if
     this bit isn't set, then it doesn't.

`RE_INVALID_INTERVAL_ORD'
     If this bit is set, a syntactically invalid interval is treated as
     a string of ordinary characters.  For example, the extended regular
     expression `a{1' is treated as `a\{1'.

`RE_LIMITED_OPS'
     If this bit is set, then Regex doesn't recognize the
     match-one-or-more, match-zero-or-one or alternation operators; if
     this bit isn't set, then it does.

`RE_NEWLINE_ALT'
     If this bit is set, then newline represents the alternation
     operator; if this bit isn't set, then newline is ordinary.

`RE_NO_BK_BRACES'
     If this bit is set, then `{' represents the open-interval operator
     and `}' represents the close-interval operator; if this bit isn't
     set, then `\{' represents the open-interval operator and `\}'
     represents the close-interval operator.  This bit is relevant only
     if `RE_INTERVALS' is set.

`RE_NO_BK_PARENS'
     If this bit is set, then `(' represents the open-group operator and
     `)' represents the close-group operator; if this bit isn't set,
     then `\(' represents the open-group operator and `\)' represents
     the close-group operator.

`RE_NO_BK_REFS'
     If this bit is set, then Regex doesn't recognize `\'DIGIT as the
     back reference operator; if this bit isn't set, then it does.

`RE_NO_BK_VBAR'
     If this bit is set, then `|' represents the alternation operator;
     if this bit isn't set, then `\|' represents the alternation
     operator.  This bit is irrelevant if `RE_LIMITED_OPS' is set.

`RE_NO_EMPTY_RANGES'
     If this bit is set, then a regular expression with a range whose
     ending point collates lower than its starting point is invalid; if
     this bit isn't set, then Regex considers such a range to be empty.

`RE_NO_GNU_OPS'
     If this bit is set, GNU regex operators are not recognized;
     otherwise, they are.

`RE_NO_POSIX_BACKTRACKING'
     If this bit is set, succeed as soon as we match the whole pattern,
     without further backtracking.  This means that a match may not be
     the leftmost longest; *note What Gets Matched?:: for what this
     means.

`RE_NO_SUB'
     If this bit is set, then `no_sub' will be set to one during
     `re_compile_pattern'.  This causes matching and searching routines
     not to record substring match information.

`RE_UNMATCHED_RIGHT_PAREN_ORD'
     If this bit is set and the regular expression has no matching
     open-group operator, then Regex considers what would otherwise be

13.2.2 Predefined Syntaxes
--------------------------

   If you're programming with Regex, you can set a pattern buffer's
(*note GNU Pattern Buffers::) syntax either to an arbitrary combination
of syntax bits (*note Syntax Bits::) or else to the configurations
defined by Regex.  These configurations define the syntaxes used by
certain programs--GNU Emacs, POSIX Awk, traditional Awk, Grep, Egrep--in
addition to syntaxes for POSIX basic and extended regular expressions.

   The predefined syntaxes--taken directly from `regex.h'--are:

     #define RE_SYNTAX_EMACS 0

     #define RE_SYNTAX_AWK                                                   \

13.2.3 Collating Elements vs. Characters
----------------------------------------

   POSIX generalizes the notion of a character to that of a collating
element.  It defines a "collating element" to be "a sequence of one or
more bytes defined in the current collating sequence as a unit of
collation."

   This generalizes the notion of a character in two ways.  First, a
single character can map into two or more collating elements.  For
example, the German "es-zet" collates as the collating element `s'
followed by another collating element `s'.  Second, two or more
characters can map into one collating element.  For example, the
Spanish `ll' collates after `l' and before `m'.

   Since POSIX's "collating element" preserves the essential idea of a
"character," we use the latter, more familiar, term in this document.


File: gnulib.info,  Node: The Backslash Character,  Prev: Collating Elements vs. Characters,  Up: Regular Expression Syntax

13.2.4 The Backslash Character
------------------------------

   The `\' character has one of four different meanings, depending on
the context in which you use it and what syntax bits are set (*note
Syntax Bits::).  It can: 1) stand for itself, 2) quote the next
character, 3) introduce an operator, or 4) do nothing.

  1. It stands for itself inside a list (*note List Operators::) if the
     syntax bit `RE_BACKSLASH_ESCAPE_IN_LISTS' is not set.  For
     example, `[\]' would match `\'.

  2. It quotes (makes ordinary, if it's special) the next character
     when you use it either:

        * outside a list,(1) or

        * inside a list and the syntax bit
          `RE_BACKSLASH_ESCAPE_IN_LISTS' is set.


  3. It introduces an operator when followed by certain ordinary
     characters--sometimes only when certain syntax bits are set.  See
     the cases `RE_BK_PLUS_QM', `RE_NO_BK_BRACES', `RE_NO_BK_VAR',
     `RE_NO_BK_PARENS', `RE_NO_BK_REF' in *note Syntax Bits::.  Also:

        * `\b' represents the match-word-boundary operator (*note
          Match-word-boundary Operator::).

        * `\B' represents the match-within-word operator (*note
          Match-within-word Operator::).

        * `\<' represents the match-beginning-of-word operator
          (*note Match-beginning-of-word Operator::).

        * `\>' represents the match-end-of-word operator (*note
          Match-end-of-word Operator::).

        * `\w' represents the match-word-constituent operator (*note
          Match-word-constituent Operator::).

        * `\W' represents the match-non-word-constituent operator
          (*note Match-non-word-constituent Operator::).

        * `\`' represents the match-beginning-of-buffer operator and
          `\'' represents the match-end-of-buffer operator (*note
          Buffer Operators::).

        * If Regex was compiled with the C preprocessor symbol `emacs'
          defined, then `\sCLASS' represents the match-syntactic-class
          operator and `\SCLASS' represents the
          match-not-syntactic-class operator (*note Syntactic Class
          Operators::).


  4. In all other cases, Regex ignores `\'.  For example, `\n' matches
     `n'.


   ---------- Footnotes ----------

   (1) Sometimes you don't have to explicitly quote special characters
to make them ordinary.  For instance, most characters lose any special
meaning inside a list (*note List Operators::).  In addition, if the
syntax bits `RE_CONTEXT_INVALID_OPS' and `RE_CONTEXT_INDEP_OPS' aren't
set, then (for historical reasons) the matcher considers special
characters ordinary if they are in contexts where the operations they
represent make no sense; for example, then the match-zero-or-more
operator (represented by `*') matches itself in the regular expression
`*foo' because there is no preceding expression on which it can
operate.  It is poor practice, however, to depend on this behavior; if
you want a special character to be ordinary outside a list, it's better
to always quote it, regardless.


File: gnulib.info,  Node: Common Operators,  Next: GNU Operators,  Prev: Regular Expression Syntax,  Up: Regular expressions

13.3 Common Operators
=====================

   You compose regular expressions from operators.  In the following
sections, we describe the regular expression operators specified by
POSIX; GNU also uses these.  Most operators have more than one
representation as characters.  *Note Regular Expression Syntax::, for
what characters represent what operators under what circumstances.

   For most operators that can be represented in two ways, one
representation is a single character and the other is that character
preceded by `\'.  For example, either `(' or `\(' represents the
open-group operator.  Which one does depends on the setting of a syntax
bit, in this case `RE_NO_BK_PARENS'.  Why is this so?  Historical
reasons dictate some of the varying representations, while POSIX
dictates others.

   Finally, almost all characters lose any special meaning inside a list
(*note List Operators::).

* Menu:

* Match-self Operator::                 Ordinary characters.
* Match-any-character Operator::        .
* Concatenation Operator::              Juxtaposition.
* Repetition Operators::                *  +  ? {}
* Alternation Operator::                |
* List Operators::                      [...]  [^...]
* Grouping Operators::                  (...)
* Back-reference Operator::             \digit
* Anchoring Operators::                 ^  $


File: gnulib.info,  Node: Match-self Operator,  Next: Match-any-character Operator,  Up: Common Operators

13.3.1 The Match-self Operator (ORDINARY CHARACTER)
---------------------------------------------------

   This operator matches the character itself.  All ordinary characters
(*note Regular Expression Syntax::) represent this operator.  For
example, `f' is always an ordinary character, so the regular expression
`f' matches only the string `f'.  In particular, it does _not_ match
the string `ff'.


File: gnulib.info,  Node: Match-any-character Operator,  Next: Concatenation Operator,  Prev: Match-self Operator,  Up: Common Operators

13.3.2 The Match-any-character Operator (`.')
---------------------------------------------

   This operator matches any single printing or nonprinting character
except it won't match a:

newline
     if the syntax bit `RE_DOT_NEWLINE' isn't set.

null
     if the syntax bit `RE_DOT_NOT_NULL' is set.


   The `.' (period) character represents this operator.  For example,
`a.b' matches any three-character string beginning with `a' and ending
with `b'.


File: gnulib.info,  Node: Concatenation Operator,  Next: Repetition Operators,  Prev: Match-any-character Operator,  Up: Common Operators

13.3.3 The Concatenation Operator
---------------------------------

   This operator concatenates two regular expressions A and B.  No
character represents this operator; you simply put B after A.  The
result is a regular expression that will match a string if A matches
its first part and B matches the rest.  For example, `xy' (two
match-self operators) matches `xy'.


File: gnulib.info,  Node: Repetition Operators,  Next: Alternation Operator,  Prev: Concatenation Operator,  Up: Common Operators

13.3.4 Repetition Operators
---------------------------

   Repetition operators repeat the preceding regular expression a
specified number of times.

* Menu:

* Match-zero-or-more Operator::  *
* Match-one-or-more Operator::   +
* Match-zero-or-one Operator::   ?
* Interval Operators::           {}


File: gnulib.info,  Node: Match-zero-or-more Operator,  Next: Match-one-or-more Operator,  Up: Repetition Operators

13.3.4.1 The Match-zero-or-more Operator (`*')
..............................................

   This operator repeats the smallest possible preceding regular
expression as many times as necessary (including zero) to match the
pattern.  `*' represents this operator.  For example, `o*' matches any
string made up of zero or more `o's.  Since this operator operates on
the smallest preceding regular expression, `fo*' has a repeating `o',
not a repeating `fo'.  So, `fo*' matches `f', `fo', `foo', and so on.

   Since the match-zero-or-more operator is a suffix operator, it may be
useless as such when no regular expression precedes it.  This is the
case when it:

   * is first in a regular expression, or

   * follows a match-beginning-of-line, open-group, or alternation
     operator.


Three different things can happen in these cases:

  1. If the syntax bit `RE_CONTEXT_INVALID_OPS' is set, then the
     regular expression is invalid.

  2. If `RE_CONTEXT_INVALID_OPS' isn't set, but `RE_CONTEXT_INDEP_OPS'
     is, then `*' represents the match-zero-or-more operator (which
     then operates on the empty string).

  3. Otherwise, `*' is ordinary.


   The matcher processes a match-zero-or-more operator by first
matching as many repetitions of the smallest preceding regular
expression as it can.  Then it continues to match the rest of the
pattern.

   If it can't match the rest of the pattern, it backtracks (as many
times as necessary), each time discarding one of the matches until it
can either match the entire pattern or be certain that it cannot get a
match.  For example, when matching `ca*ar' against `caaar', the matcher
first matches all three `a's of the string with the `a*' of the regular
expression.  However, it cannot then match the final `ar' of the
regular expression against the final `r' of the string.  So it
backtracks, discarding the match of the last `a' in the string.  It can
then match the remaining `ar'.

13.3.4.2 The Match-one-or-more Operator (`+' or `\+')
.....................................................

   If the syntax bit `RE_LIMITED_OPS' is set, then Regex doesn't
recognize this operator.  Otherwise, if the syntax bit `RE_BK_PLUS_QM'
isn't set, then `+' represents this operator; if it is, then `\+' does.

   This operator is similar to the match-zero-or-more operator except
that it repeats the preceding regular expression at least once; *note
Match-zero-or-more Operator::, for what it operates on, how some syntax
bits affect it, and how Regex backtracks to match it.

   For example, supposing that `+' represents the match-one-or-more
operator; then `ca+r' matches, e.g., `car' and `caaaar', but not `cr'.

13.3.4.3 The Match-zero-or-one Operator (`?' or `\?')
.....................................................

   If the syntax bit `RE_LIMITED_OPS' is set, then Regex doesn't
recognize this operator.  Otherwise, if the syntax bit `RE_BK_PLUS_QM'
isn't set, then `?' represents this operator; if it is, then `\?' does.

   This operator is similar to the match-zero-or-more operator except
that it repeats the preceding regular expression once or not at all;
*note Match-zero-or-more Operator::, to see what it operates on, how
some syntax bits affect it, and how Regex backtracks to match it.

   For example, supposing that `?' represents the match-zero-or-one
operator; then `ca?r' matches both `car' and `cr', but nothing else.


File: gnulib.info,  Node: Interval Operators,  Prev: Match-zero-or-one Operator,  Up: Repetition Operators

13.3.4.4 Interval Operators (`{' ... `}' or `\{' ... `\}')
..........................................................

   If the syntax bit `RE_INTERVALS' is set, then Regex recognizes
"interval expressions".  They repeat the smallest possible preceding
regular expression a specified number of times.

   If the syntax bit `RE_NO_BK_BRACES' is set, `{' represents the
"open-interval operator" and `}' represents the "close-interval
operator" ; otherwise, `\{' and `\}' do.

   Specifically, supposing that `{' and `}' represent the open-interval
and close-interval operators; then:

`{COUNT}'
     matches exactly COUNT occurrences of the preceding regular
     expression.

`{MIN,}'
     matches MIN or more occurrences of the preceding regular
     expression.

`{MIN, MAX}'
     matches at least MIN but no more than MAX occurrences of the
     preceding regular expression.


   The interval expression (but not necessarily the regular expression
that contains it) is invalid if:

   * MIN is greater than MAX, or

   * any of COUNT, MIN, or MAX are outside the range zero to
     `RE_DUP_MAX' (which symbol `regex.h' defines).


   If the interval expression is invalid and the syntax bit
`RE_NO_BK_BRACES' is set, then Regex considers all the characters in
the would-be interval to be ordinary.  If that bit isn't set, then the
regular expression is invalid.

   If the interval expression is valid but there is no preceding regular
expression on which to operate, then if the syntax bit
`RE_CONTEXT_INVALID_OPS' is set, the regular expression is invalid.  If
that bit isn't set, then Regex considers all the characters--other than
backslashes, which it ignores--in the would-be interval to be ordinary.


File: gnulib.info,  Node: Alternation Operator,  Next: List Operators,  Prev: Repetition Operators,  Up: Common Operators

13.3.5 The Alternation Operator (`|' or `\|')
---------------------------------------------

   If the syntax bit `RE_LIMITED_OPS' is set, then Regex doesn't
recognize this operator.  Otherwise, if the syntax bit `RE_NO_BK_VBAR'
is set, then `|' represents this operator; otherwise, `\|' does.

   Alternatives match one of a choice of regular expressions: if you
put the character(s) representing the alternation operator between any
two regular expressions A and B, the result matches the union of the
strings that A and B match.  For example, supposing that `|' is the
alternation operator, then `foo|bar|quux' would match any of `foo',
`bar' or `quux'.

   The alternation operator operates on the _largest_ possible
surrounding regular expressions.  (Put another way, it has the lowest
precedence of any regular expression operator.)  Thus, the only way you
can delimit its arguments is to use grouping.  For example, if `(' and
`)' are the open and close-group operators, then `fo(o|b)ar' would
match either `fooar' or `fobar'.  (`foo|bar' would match `foo' or
`bar'.)

   The matcher usually tries all combinations of alternatives so as to
match the longest possible string.  For example, when matching
`(fooq|foo)*(qbarquux|bar)' against `fooqbarquux', it cannot take, say,
the first ("depth-first") combination it could match, since then it
would be content to match just `fooqbar'.

   Note that since the default behavior is to return the leftmost
longest match, when more than one of a series of alternatives matches
the actual match will be the longest matching alternative, not
necessarily the first in the list.


File: gnulib.info,  Node: List Operators,  Next: Grouping Operators,  Prev: Alternation Operator,  Up: Common Operators

13.3.6 List Operators (`[' ... `]' and `[^' ... `]')
----------------------------------------------------

   "Lists", also called "bracket expressions", are a set of one or more
items.  An "item" is a character, a collating symbol, an equivalence
class expression, a character class expression, or a range expression.
The syntax bits affect which kinds of items you can put in a list.  We
explain the last four items in subsections below.  Empty lists are
invalid.

   A "matching list" matches a single character represented by one of
the list items.  You form a matching list by enclosing one or more items
within an "open-matching-list operator" (represented by `[') and a
"close-list operator" (represented by `]').

   For example, `[ab]' matches either `a' or `b'.  `[ad]*' matches the
empty string and any string composed of just `a's and `d's in any
order.  Regex considers invalid a regular expression with a `[' but no
matching `]'.

   "Nonmatching lists" are similar to matching lists except that they
match a single character _not_ represented by one of the list items.
You use an "open-nonmatching-list operator" (represented by `[^'(1))
instead of an open-matching-list operator to start a nonmatching list.

   For example, `[^ab]' matches any character except `a' or `b'.

   If the syntax bit `RE_HAT_LISTS_NOT_NEWLINE' is set, then
nonmatching lists do not match a newline.

   Most characters lose any special meaning inside a list.  The special
characters inside a list follow.

`]'
     ends the list if it's not the first list item.  So, if you want to
     make the `]' character a list item, you must put it first.

`\'
     quotes the next character if the syntax bit
     `RE_BACKSLASH_ESCAPE_IN_LISTS' is set.

`[.'
     represents the open-collating-symbol operator (*note Collating
     Symbol Operators::).

`.]'
     represents the close-collating-symbol operator.

`[='
     represents the open-equivalence-class operator (*note Equivalence
     Class Operators::).

`=]'
     represents the close-equivalence-class operator.

`[:'
     represents the open-character-class operator (*note Character
     Class Operators::) if the syntax bit `RE_CHAR_CLASSES' is set and
     what follows is a valid character class expression.

`:]'
     represents the close-character-class operator if the syntax bit
     `RE_CHAR_CLASSES' is set and what precedes it is an
     open-character-class operator followed by a valid character class
     name.

`-'
     represents the range operator (*note Range Operator::) if it's not
     first or last in a list or the ending point of a range.


All other characters are ordinary.  For example, `[.*]' matches `.' and
`*'.

* Menu:

* Collating Symbol Operators::  [.elem.]
* Equivalence Class Operators:: [=class=]
* Character Class Operators::   [:class:]
* Range Operator::          start-end

   ---------- Footnotes ----------

   (1) Regex therefore doesn't consider the `^' to be the first
character in the list.  If you put a `^' character first in (what you
think is) a matching list, you'll turn it into a nonmatching list.

13.3.6.1 Collating Symbol Operators (`[.' ... `.]')
...................................................

   Collating symbols can be represented inside lists.  You form a
"collating symbol" by putting a collating element between an
"open-collating-symbol operator" and a "close-collating-symbol
operator".  `[.' represents the open-collating-symbol operator and `.]'
represents the close-collating-symbol operator.  For example, if `ll'
is a collating element, then `[[.ll.]]' would match `ll'.


File: gnulib.info,  Node: Equivalence Class Operators,  Next: Character Class Operators,  Prev: Collating Symbol Operators,  Up: List Operators

13.3.6.2 Equivalence Class Operators (`[=' ... `=]')
....................................................

   Regex recognizes equivalence class expressions inside lists.  A
"equivalence class expression" is a set of collating elements which all
belong to the same equivalence class.  You form an equivalence class
expression by putting a collating element between an
"open-equivalence-class operator" and a "close-equivalence-class
operator".  `[=' represents the open-equivalence-class operator and
`=]' represents the close-equivalence-class operator.  For example, if
`a' and `A' were an equivalence class, then both `[[=a=]]' and `[[=A=]]'
would match both `a' and `A'.  If the collating element in an
equivalence class expression isn't part of an equivalence class, then
the matcher considers the equivalence class expression to be a collating

13.3.6.3 Character Class Operators (`[:' ... `:]')
..................................................

   If the syntax bit `RE_CHAR_CLASSES' is set, then Regex recognizes
character class expressions inside lists.  A "character class
expression" matches one character from a given class.  You form a
character class expression by putting a character class name between an
"open-character-class operator" (represented by `[:') and a
"close-character-class operator" (represented by `:]').  The character
class names and their meanings are:

`alnum'
     letters and digits

`alpha'
     letters

`blank'
     system-dependent; for GNU, a space or tab

`cntrl'
     control characters (in the ASCII encoding, code 0177 and codes
     less than 040)

`digit'
     digits

`graph'
     same as `print' except omits space

`lower'
     lowercase letters

`print'
     printable characters (in the ASCII encoding, space tilde--codes
     040 through 0176)

`punct'
     neither control nor alphanumeric characters

`space'
     space, carriage return, newline, vertical tab, and form feed

`upper'
     uppercase letters

`xdigit'
     hexadecimal digits: `0'-`9', `a'-`f', `A'-`F'


These correspond to the definitions in the C library's `<ctype.h>'
facility.  For example, `[:alpha:]' corresponds to the standard
facility `isalpha'.  Regex recognizes character class expressions only
inside of lists; so `[[:alpha:]]' matches any letter, but `[:alpha:]'
outside of a bracket expression and not followed by a repetition
operator matches just itself.


File: gnulib.info,  Node: Range Operator,  Prev: Character Class Operators,  Up: List Operators

13.3.6.4 The Range Operator (`-')
.................................

   Regex recognizes "range expressions" inside a list. They represent
those characters that fall between two elements in the current
collating sequence.  You form a range expression by putting a "range
operator" between two of any of the following: characters, collating
elements, collating symbols, and equivalence class expressions.  The
starting point of the range and the ending point of the range don't
have to be the same kind of item, e.g., the starting point could be a
collating element and the ending point could be an equivalence class
expression.  If a range's ending point is an equivalence class, then
all the collating elements in that class will be in the range.(1) `-'
represents the range operator.  For example, `a-f' within a list
represents all the characters from `a' through `f' inclusively.

   If the syntax bit `RE_NO_EMPTY_RANGES' is set, then if the range's
ending point collates less than its starting point, the range (and the
regular expression containing it) is invalid.  For example, the regular
expression `[z-a]' would be invalid.  If this bit isn't set, then Regex
considers such a range to be empty.

   Since `-' represents the range operator, if you want to make a `-'
character itself a list item, you must do one of the following:

   * Put the `-' either first or last in the list.

   * Include a range whose starting point collates strictly lower than
     `-' and whose ending point collates equal or higher.  Unless a
     range is the first item in a list, a `-' can't be its starting
     point, but _can_ be its ending point.  That is because Regex
     considers `-' to be the range operator unless it is preceded by
     another `-'.  For example, in the ASCII encoding, `)', `*', `+',
     `,', `-', `.', and `/' are contiguous characters in the collating
     sequence.  You might think that `[)-+--/]' has two ranges: `)-+'
     and `--/'.  Rather, it has the ranges `)-+' and `+--', plus the
     character `/', so it matches, e.g., `,', not `.'.

   * Put a range whose starting point is `-' first in the list.


   For example, `[-a-z]' matches a lowercase letter or a hyphen (in
English, in ASCII).

   ---------- Footnotes ----------

   (1) You can't use a character class for the starting or ending point
of a range, since a character class is not a single character.


File: gnulib.info,  Node: Grouping Operators,  Next: Back-reference Operator,  Prev: List Operators,  Up: Common Operators

13.3.7 Grouping Operators (`(' ... `)' or `\(' ... `\)')
--------------------------------------------------------

   A "group", also known as a "subexpression", consists of an
"open-group operator", any number of other operators, and a
"close-group operator".  Regex treats this sequence as a unit, just as
mathematics and programming languages treat a parenthesized expression
as a unit.

   Therefore, using "groups", you can:

   * delimit the argument(s) to an alternation operator (*note
     Alternation Operator::) or a repetition operator (*note Repetition
     Operators::).

   * keep track of the indices of the substring that matched a given
     group.  *Note Using Registers::, for a precise explanation.  This
     lets you:

        * use the back-reference operator (*note Back-reference
          Operator::).

        * use registers (*note Using Registers::).



   If the syntax bit `RE_NO_BK_PARENS' is set, then `(' represents the
open-group operator and `)' represents the close-group operator;
otherwise, `\(' and `\)' do.

   If the syntax bit `RE_UNMATCHED_RIGHT_PAREN_ORD' is set and a
close-group operator has no matching open-group operator, then Regex
considers it to match `)'.


File: gnulib.info,  Node: Back-reference Operator,  Next: Anchoring Operators,  Prev: Grouping Operators,  Up: Common Operators

13.3.8 The Back-reference Operator ("\"DIGIT)
---------------------------------------------

   If the syntax bit `RE_NO_BK_REF' isn't set, then Regex recognizes
back references.  A back reference matches a specified preceding group.
The back reference operator is represented by `\DIGIT' anywhere after
the end of a regular expression's DIGIT-th group (*note Grouping
Operators::).

   DIGIT must be between `1' and `9'.  The matcher assigns numbers 1
through 9 to the first nine groups it encounters.  By using one of `\1'
through `\9' after the corresponding group's close-group operator, you
can match a substring identical to the one that the group does.

   Back references match according to the following (in all examples
below, `(' represents the open-group, `)' the close-group, `{' the
open-interval and `}' the close-interval operator):

   * If the group matches a substring, the back reference matches an
     identical substring.  For example, `(a)\1' matches `aa' and
     `(bana)na\1bo\1' matches `bananabanabobana'.  Likewise, `(.*)\1'
     matches any (newline-free if the syntax bit `RE_DOT_NEWLINE' isn't
     set) string that is composed of two identical halves; the `(.*)'
     matches the first half and the `\1' matches the second half.

   * If the group matches more than once (as it might if followed by,
     e.g., a repetition operator), then the back reference matches the
     substring the group _last_ matched.  For example, `((a*)b)*\1\2'
     matches `aabababa'; first group 1 (the outer one) matches `aab'
     and group 2 (the inner one) matches `aa'.  Then group 1 matches
     `ab' and group 2 matches `a'.  So, `\1' matches `ab' and `\2'
     matches `a'.

   * If the group doesn't participate in a match, i.e., it is part of an
     alternative not taken or a repetition operator allows zero
     repetitions of it, then the back reference makes the whole match
     fail.  For example, `(one()|two())-and-(three\2|four\3)' matches
     `one-and-three' and `two-and-four', but not `one-and-four' or
     `two-and-three'.  For example, if the pattern matches `one-and-',
     then its group 2 matches the empty string and its group 3 doesn't
     participate in the match.  So, if it then matches `four', then
     when it tries to back reference group 3--which it will attempt to
     do because `\3' follows the `four'--the match will fail because
     group 3 didn't participate in the match.


   You can use a back reference as an argument to a repetition
operator.  For example, `(a(b))\2*' matches `a' followed by two or more
`b's.  Similarly, `(a(b))\2{3}' matches `abbbb'.

   If there is no preceding DIGIT-th subexpression, the regular
expression is invalid.

13.3.9 Anchoring Operators
--------------------------

   These operators can constrain a pattern to match only at the
beginning or end of the entire string or at the beginning or end of a
line.

* Menu:

* Match-beginning-of-line Operator::  ^
* Match-end-of-line Operator::        $


File: gnulib.info,  Node: Match-beginning-of-line Operator,  Next: Match-end-of-line Operator,  Up: Anchoring Operators

13.3.9.1 The Match-beginning-of-line Operator (`^')
...................................................

   This operator can match the empty string either at the beginning of
the string or after a newline character.  Thus, it is said to "anchor"
the pattern to the beginning of a line.

   In the cases following, `^' represents this operator.  (Otherwise,
`^' is ordinary.)

   * It (the `^') is first in the pattern, as in `^foo'.

   * The syntax bit `RE_CONTEXT_INDEP_ANCHORS' is set, and it is outside
     a bracket expression.

   * It follows an open-group or alternation operator, as in `a\(^b\)'
     and `a\|^b'.  *Note Grouping Operators::, and *note Alternation
     Operator::.


   These rules imply that some valid patterns containing `^' cannot be
matched; for example, `foo^bar' if `RE_CONTEXT_INDEP_ANCHORS' is set.

   If the `not_bol' field is set in the pattern buffer (*note GNU
Pattern Buffers::), then `^' fails to match at the beginning of the
string.  This lets you match against pieces of a line, as you would
need to if, say, searching for repeated instances of a given pattern in
a line; it would work correctly for patterns both with and without
match-beginning-of-line operators.


File: gnulib.info,  Node: Match-end-of-line Operator,  Prev: Match-beginning-of-line Operator,  Up: Anchoring Operators

13.3.9.2 The Match-end-of-line Operator (`$')
.............................................

   This operator can match the empty string either at the end of the
string or before a newline character in the string.  Thus, it is said
to "anchor" the pattern to the end of a line.

   It is always represented by `$'.  For example, `foo$' usually
matches, e.g., `foo' and, e.g., the first three characters of
`foo\nbar'.

   Its interaction with the syntax bits and pattern buffer fields is
exactly the dual of `^''s; see the previous section.  (That is, "`^'"
becomes "`$'", "beginning" becomes "end", "next" becomes "previous",
"after" becomes "before", and "`not_bol'" becomes "`not_eol'".)

13.4.1 Word Operators
---------------------

   The operators in this section require Regex to recognize parts of
words.  Regex uses a syntax table to determine whether or not a
character is part of a word, i.e., whether or not it is
"word-constituent".

File: gnulib.info,  Node: Non-Emacs Syntax Tables,  Next: Match-word-boundary Operator,  Up: Word Operators

13.4.1.1 Non-Emacs Syntax Tables
................................

   A "syntax table" is an array indexed by the characters in your
character set.  In the ASCII encoding, therefore, a syntax table has
256 elements.  Regex always uses a `char *' variable `re_syntax_table'
as its syntax table.  In some cases, it initializes this variable and
in others it expects you to initialize it.

   * If Regex is compiled with the preprocessor symbols `emacs' and
     `SYNTAX_TABLE' both undefined, then Regex allocates
     `re_syntax_table' and initializes an element I either to `Sword'
     (which it defines) if I is a letter, number, or `_', or to zero if
     it's not.

   * If Regex is compiled with `emacs' undefined but `SYNTAX_TABLE'
     defined, then Regex expects you to define a `char *' variable
     `re_syntax_table' to be a valid syntax table.

   * *Note Emacs Syntax Tables::, for what happens when Regex is
     compiled with the preprocessor symbol `emacs' defined.

13.5.1.2 The Match-syntactic-class Operator (`\s'CLASS)
.......................................................

   This operator matches any character whose syntactic class is
represented by a specified character.  `\sCLASS' represents this
operator where CLASS is the character representing the syntactic class
you want.  For example, `w' represents the syntactic class of
word-constituent characters, so `\sw' matches any word-constituent
character.

13.5.1.3 The Match-not-syntactic-class Operator (`\S'CLASS)
...........................................................

   This operator is similar to the match-syntactic-class operator except
that it matches any character whose syntactic class is _not_
represented by the specified character.  `\SCLASS' represents this
operator.  For example, `w' represents the syntactic class of
word-constituent characters, so `\Sw' matches any character that is not
word-constituent.

13.6 What Gets Matched?
=======================

   Regex usually matches strings according to the "leftmost longest"
rule; that is, it chooses the longest of the leftmost matches.  This
does not mean that for a regular expression containing subexpressions
that it simply chooses the longest match for each subexpression, left to
right; the overall match must also be the longest possible one.

   For example, `(ac*)(c*d[ac]*)\1' matches `acdacaaa', not `acdac', as
it would if it were to choose the longest match for the first
subexpression.

   Here we describe how you use the Regex data structures and functions
in C programs.  Regex has three interfaces: one designed for GNU, one
compatible with POSIX (as specified by POSIX, draft 1003.2/D11.2), and
one compatible with Berkeley UNIX.  The POSIX interface is not
documented here; see the documentation of GNU libc, or the POSIX man
pages.  The Berkeley UNIX interface is documented here for convenience,
since its documentation is not otherwise readily available on GNU
systems.

13.7.1.1 GNU Pattern Buffers
............................

   To compile, match, or search for a given regular expression, you must
supply a pattern buffer.  A "pattern buffer" holds one compiled regular
expression.(1)

   You can have several different pattern buffers simultaneously, each
holding a compiled pattern for a different regular expression.

   `regex.h' defines the pattern buffer `struct' with the following
public fields:

       unsigned char *buffer;
       unsigned long allocated;
       char *fastmap;
       char *translate;
       size_t re_nsub;
       unsigned no_sub : 1;
       unsigned not_bol : 1;
       unsigned not_eol : 1;

   ---------- Footnotes ----------

   (1) Regular expressions are also referred to as "patterns," hence
the name "pattern buffer."


File: gnulib.info,  Node: GNU Regular Expression Compiling,  Next: GNU Matching,  Prev: GNU Pattern Buffers,  Up: GNU Regex Functions

13.7.1.2 GNU Regular Expression Compiling
.........................................

   In GNU, you can both match and search for a given regular
expression.  To do either, you must first compile it in a pattern buffer
(*note GNU Pattern Buffers::).

   Regular expressions match according to the syntax with which they
were compiled; with GNU, you indicate what syntax you want by setting
the variable `re_syntax_options' (declared in `regex.h') before calling
the compiling function, `re_compile_pattern' (see below).  *Note Syntax
Bits::, and *note Predefined Syntaxes::.

   You can change the value of `re_syntax_options' at any time.
Usually, however, you set its value once and then never change it.

   `re_compile_pattern' takes a pattern buffer as an argument.  You
must initialize the following fields:

`translate initialization'

`translate'
     Initialize this to point to a translate table if you want one, or
     to zero if you don't.  We explain translate tables in *note GNU
     Translate Tables::.

`fastmap'
     Initialize this to nonzero if you want a fastmap, or to zero if you
     don't.

`buffer'
`allocated'
     If you want `re_compile_pattern' to allocate memory for the
     compiled pattern, set both of these to zero.  If you have an
     existing block of memory (allocated with `malloc') you want Regex
     to use, set `buffer' to its address and `allocated' to its size (in
     bytes).

     `re_compile_pattern' uses `realloc' to extend the space for the
     compiled pattern as necessary.


   To compile a pattern buffer, use:

     char *
     re_compile_pattern (const char *REGEX, const int REGEX_SIZE,
                         struct re_pattern_buffer *PATTERN_BUFFER)

REGEX is the regular expression's address, REGEX_SIZE is its length,
and PATTERN_BUFFER is the pattern buffer's address.

   If `re_compile_pattern' successfully compiles the regular
expression, it returns zero and sets `*PATTERN_BUFFER' to the compiled
pattern.  It sets the pattern buffer's fields as follows:

`buffer'
     to the compiled pattern.

`syntax'
     to the current value of `re_syntax_options'.

`re_nsub'
     to the number of subexpressions in REGEX.


   If `re_compile_pattern' can't compile REGEX, it returns an error
string corresponding to a POSIX error code.

13.7.1.3 GNU Matching
.....................

   Matching the GNU way means trying to match as much of a string as
possible starting at a position within it you specify.  Once you've
compiled a pattern into a pattern buffer (*note GNU Regular Expression
Compiling::), you can ask the matcher to match that pattern against a
string using:

     int
     re_match (struct re_pattern_buffer *PATTERN_BUFFER,
               const char *STRING, const int SIZE,
               const int START, struct re_registers *REGS)

PATTERN_BUFFER is the address of a pattern buffer containing a compiled
pattern.  STRING is the string you want to match; it can contain
newline and null characters.  SIZE is the length of that string.  START
is the string index at which you want to begin matching; the first
character of STRING is at index zero.  *Note Using Registers::, for an
explanation of REGS; you can safely pass zero.

   `re_match' matches the regular expression in PATTERN_BUFFER against
the string STRING according to the syntax of PATTERN_BUFFER.  (*Note
GNU Regular Expression Compiling::, for how to set it.)  The function
returns -1 if the compiled pattern does not match any part of STRING
and -2 if an internal error happens; otherwise, it returns how many
(possibly zero) characters of STRING the pattern matched.

   An example: suppose PATTERN_BUFFER points to a pattern buffer
containing the compiled pattern for `a*', and STRING points to `aaaaab'
(whereupon SIZE should be 6). Then if START is 2, `re_match' returns 3,
i.e., `a*' would have matched the last three `a's in STRING.  If START
is 0, `re_match' returns 5, i.e., `a*' would have matched all the `a's
in STRING.  If START is either 5 or 6, it returns zero.

   If START is not between zero and SIZE, then `re_match' returns -1.

13.7.1.4 GNU Searching
......................

   "Searching" means trying to match starting at successive positions
within a string.  The function `re_search' does this.

   Before calling `re_search', you must compile your regular
expression.  *Note GNU Regular Expression Compiling::.

   Here is the function declaration:

     int
     re_search (struct re_pattern_buffer *PATTERN_BUFFER,
                const char *STRING, const int SIZE,
                const int START, const int RANGE,
                struct re_registers *REGS)

whose arguments are the same as those to `re_match' (*note GNU
Matching::) except that the two arguments START and RANGE replace
`re_match''s argument START.

   If RANGE is positive, then `re_search' attempts a match starting
first at index START, then at START + 1 if that fails, and so on, up to
START + RANGE; if RANGE is negative, then it attempts a match starting
first at index START, then at START -1 if that fails, and so on.

   If START is not between zero and SIZE, then `re_search' returns -1.
When RANGE is positive, `re_search' adjusts RANGE so that START + RANGE
- 1 is between zero and SIZE, if necessary; that way it won't search
outside of STRING.  Similarly, when RANGE is negative, `re_search'
adjusts RANGE so that START + RANGE + 1 is between zero and SIZE, if
necessary.

   If the `fastmap' field of PATTERN_BUFFER is zero, `re_search'
matches starting at consecutive positions; otherwise, it uses `fastmap'
to make the search more efficient.  *Note Searching with Fastmaps::.

   If no match is found, `re_search' returns -1.  If a match is found,
it returns the index where the match began.  If an internal error
happens, it returns -2.

13.7.1.5 Matching and Searching with Split Data
...............................................

   Using the functions `re_match_2' and `re_search_2', you can match or
search in data that is divided into two strings.

   The function:

     int
     re_match_2 (struct re_pattern_buffer *BUFFER,
                 const char *STRING1, const int SIZE1,
                 const char *STRING2, const int SIZE2,
                 const int START,
                 struct re_registers *REGS,
                 const int STOP)

is similar to `re_match' (*note GNU Matching::) except that you pass
_two_ data strings and sizes, and an index STOP beyond which you don't
want the matcher to try matching.  As with `re_match', if it succeeds,
`re_match_2' returns how many characters of STRING it matched.  Regard
STRING1 and STRING2 as concatenated when you set the arguments START and
STOP and use the contents of REGS; `re_match_2' never returns a value
larger than SIZE1 + SIZE2.

   The function:

     int
     re_search_2 (struct re_pattern_buffer *BUFFER,
                  const char *STRING1, const int SIZE1,
                  const char *STRING2, const int SIZE2,
                  const int START, const int RANGE,
                  struct re_registers *REGS,
                  const int STOP)

is similarly related to `re_search'.

13.7.1.6 Searching with Fastmaps
................................

   If you're searching through a long string, you should use a fastmap.
Without one, the searcher tries to match at consecutive positions in the
string.  Generally, most of the characters in the string could not start
a match.  It takes much longer to try matching at a given position in
the string than it does to check in a table whether or not the
character at that position could start a match.  A "fastmap" is such a
table.

   More specifically, a fastmap is an array indexed by the characters in
your character set.  Under the ASCII encoding, therefore, a fastmap has
256 elements.  If you want the searcher to use a fastmap with a given
pattern buffer, you must allocate the array and assign the array's
address to the pattern buffer's `fastmap' field.  You either can
compile the fastmap yourself or have `re_search' do it for you; when
`fastmap' is nonzero, it automatically compiles a fastmap the first
time you search using a particular compiled pattern.

   By setting the buffer’s `fastmap' field before calling
`re_compile_pattern', you can reuse a buffer data structure across
multiple searches with different patterns, and allocate the fastmap only
once.  Nonetheless, the fastmap must be recompiled each time the buffer
has a new pattern compiled into it.

   To compile a fastmap yourself, use:

     int
     re_compile_fastmap (struct re_pattern_buffer *PATTERN_BUFFER)

PATTERN_BUFFER is the address of a pattern buffer.  If the character C
could start a match for the pattern, `re_compile_fastmap' makes
`PATTERN_BUFFER->fastmap[C]' nonzero.  It returns 0 if it can compile a
fastmap and -2 if there is an internal error.  For example, if `|' is
the alternation operator and PATTERN_BUFFER holds the compiled pattern
for `a|b', then `re_compile_fastmap' sets `fastmap['a']' and
`fastmap['b']' (and no others).

   `re_search' uses a fastmap as it moves along in the string: it
checks the string's characters until it finds one that's in the fastmap.
Then it tries matching at that character.  If the match fails, it
repeats the process.  So, by using a fastmap, `re_search' doesn't waste
time trying to match at positions in the string that couldn't start a
match.

   If you don't want `re_search' to use a fastmap, store zero in the
`fastmap' field of the pattern buffer before calling `re_search'.

   Once you've initialized a pattern buffer's `fastmap' field, you need
never do so again--even if you compile a new pattern in it--provided
the way the field is set still reflects whether or not you want a
fastmap.  `re_search' will still either do nothing if `fastmap' is null
or, if it isn't, compile a new fastmap for the new pattern.


File: gnulib.info,  Node: GNU Translate Tables,  Next: Using Registers,  Prev: Searching with Fastmaps,  Up: GNU Regex Functions

13.7.1.7 GNU Translate Tables
.............................

   If you set the `translate' field of a pattern buffer to a translate
table, then the GNU Regex functions to which you've passed that pattern
buffer use it to apply a simple transformation to all the regular
expression and string characters at which they look.

   A "translate table" is an array indexed by the characters in your
character set.  Under the ASCII encoding, therefore, a translate table
has 256 elements.  The array's elements are also characters in your
character set.  When the Regex functions see a character C, they use
`translate[C]' in its place, with one exception: the character after a
`\' is not translated.  (This ensures that, the operators, e.g., `\B'
and `\b', are always distinguishable.)

   For example, a table that maps all lowercase letters to the
corresponding uppercase ones would cause the matcher to ignore
differences in case.(1)  Such a table would map all characters except
lowercase letters to themselves, and lowercase letters to the
corresponding uppercase ones.  Under the ASCII encoding, here's how you
could initialize such a table (we'll call it `case_fold'):

     for (i = 0; i < 256; i++)
       case_fold[i] = i;
     for (i = 'a'; i <= 'z'; i++)
       case_fold[i] = i - ('a' - 'A');

   You tell Regex to use a translate table on a given pattern buffer by
assigning that table's address to the `translate' field of that buffer.
If you don't want Regex to do any translation, put zero into this
field.  You'll get weird results if you change the table's contents
anytime between compiling the pattern buffer, compiling its fastmap, and
matching or searching with the pattern buffer.

   ---------- Footnotes ----------

   (1) A table that maps all uppercase letters to the corresponding
lowercase ones would work just as well for this purpose.

13.7.1.8 Using Registers
........................

   A group in a regular expression can match a (possibly empty)
substring of the string that regular expression as a whole matched.
The matcher remembers the beginning and end of the substring matched by
each group.

   To find out what they matched, pass a nonzero REGS argument to a GNU
matching or searching function (*note GNU Matching:: and *note GNU
Searching::), i.e., the address of a structure of this type, as defined
in `regex.h':

     struct re_registers
     {
       unsigned num_regs;
       regoff_t *start;
       regoff_t *end;
     };

   Except for (possibly) the NUM_REGS'th element (see below), the Ith
element of the `start' and `end' arrays records information about the
Ith group in the pattern.  (They're declared as C pointers, but this is
only because not all C compilers accept zero-length arrays;
conceptually, it is simplest to think of them as arrays.)

   The `start' and `end' arrays are allocated in one of two ways.  The
simplest and perhaps most useful is to let the matcher (re)allocate
enough space to record information for all the groups in the regular
expression.  If `re_set_registers' is not called before searching or
matching, then the matcher allocates two arrays each of 1 + RE_NSUB
elements (RE_NSUB is another field in the pattern buffer; *note GNU
Pattern Buffers::).  The extra element is set to -1.  Then on
subsequent calls with the same pattern buffer and REGS arguments, the
matcher reallocates more space if necessary.

   The function:

     void
     re_set_registers (struct re_pattern_buffer *BUFFER,
     			      struct re_registers *REGS,
     			      size_t NUM_REGS,
     			      regoff_t *STARTS, regoff_t *ENDS)

sets REGS to hold NUM_REGS registers, storing them in STARTS and ENDS.
Subsequent matches using BUFFER and REGS will use this memory for
recording register information.  STARTS and ENDS must be allocated with
malloc, and must each be at least NUM_REGS * `sizeof (regoff_t)' bytes
long.

   If NUM_REGS is zero, then subsequent matches should allocate their
own register data.

   Unless this function is called, the first search or match using
BUFFER will allocate its own register data, without freeing the old
data.

   The following examples illustrate the information recorded in the
`re_registers' structure.  (In all of them, `(' represents the
open-group and `)' the close-group operator.  The first character in
the string STRING is at index 0.)

   * If the regular expression has an I-th group that matches a
     substring of STRING, then the function sets `REGS->start[I]' to
     the index in STRING where the substring matched by the I-th group
     begins, and `REGS->end[I]' to the index just beyond that
     substring's end.  The function sets `REGS->start[0]' and
     `REGS->end[0]' to analogous information about the entire pattern.

     For example, when you match `((a)(b))' against `ab', you get:

        * 0 in `REGS->start[0]' and 2 in `REGS->end[0]'

        * 0 in `REGS->start[1]' and 2 in `REGS->end[1]'

        * 0 in `REGS->start[2]' and 1 in `REGS->end[2]'

        * 1 in `REGS->start[3]' and 2 in `REGS->end[3]'

   * If a group matches more than once (as it might if followed by,
     e.g., a repetition operator), then the function reports the
     information about what the group _last_ matched.

     For example, when you match the pattern `(a)*' against the string
     `aa', you get:

        * 0 in `REGS->start[0]' and 2 in `REGS->end[0]'

        * 1 in `REGS->start[1]' and 2 in `REGS->end[1]'

   * If the I-th group does not participate in a successful match,
     e.g., it is an alternative not taken or a repetition operator
     allows zero repetitions of it, then the function sets
     `REGS->start[I]' and `REGS->end[I]' to -1.

     For example, when you match the pattern `(a)*b' against the string
     `b', you get:

        * 0 in `REGS->start[0]' and 1 in `REGS->end[0]'

        * -1 in `REGS->start[1]' and -1 in `REGS->end[1]'

   * If the I-th group matches a zero-length string, then the function
     sets `REGS->start[I]' and `REGS->end[I]' to the index just beyond
     that zero-length string.

     For example, when you match the pattern `(a*)b' against the string
     `b', you get:

        * 0 in `REGS->start[0]' and 1 in `REGS->end[0]'

        * 0 in `REGS->start[1]' and 0 in `REGS->end[1]'

   * If an I-th group contains a J-th group in turn not contained
     within any other group within group I and the function reports a
     match of the I-th group, then it records in `REGS->start[J]' and
     `REGS->end[J]' the last match (if it matched) of the J-th group.

     For example, when you match the pattern `((a*)b)*' against the
     string `abb', group 2 last matches the empty string, so you get
     what it previously matched:

        * 0 in `REGS->start[0]' and 3 in `REGS->end[0]'

        * 2 in `REGS->start[1]' and 3 in `REGS->end[1]'

        * 2 in `REGS->start[2]' and 2 in `REGS->end[2]'

     When you match the pattern `((a)*b)*' against the string `abb',
     group 2 doesn't participate in the last match, so you get:

        * 0 in `REGS->start[0]' and 3 in `REGS->end[0]'

        * 2 in `REGS->start[1]' and 3 in `REGS->end[1]'

        * 0 in `REGS->start[2]' and 1 in `REGS->end[2]'

   * If an I-th group contains a J-th group in turn not contained
     within any other group within group I and the function sets
     `REGS->start[I]' and `REGS->end[I]' to -1, then it also sets
     `REGS->start[J]' and `REGS->end[J]' to -1.

     For example, when you match the pattern `((a)*b)*c' against the
     string `c', you get:

        * 0 in `REGS->start[0]' and 1 in `REGS->end[0]'

        * -1 in `REGS->start[1]' and -1 in `REGS->end[1]'

        * -1 in `REGS->start[2]' and -1 in `REGS->end[2]'

13.7.1.9 Freeing GNU Pattern Buffers
....................................

   To free any allocated fields of a pattern buffer, use the POSIX
function `regfree':

     void
     regfree (regex_t *PREG)

PREG is the pattern buffer whose allocated fields you want freed; this
works because since the type `regex_t'--the type for POSIX pattern
buffers--is equivalent to the type `re_pattern_buffer'.

   `regfree' also sets PREG's `allocated' field to zero.  After a
buffer has been freed, it must have a regular expression compiled in it
before passing it to a matching or searching function.

13.7.2 BSD Regex Functions
--------------------------

   If you're writing code that has to be Berkeley UNIX compatible,
you'll need to use these functions whose interfaces are the same as
those in Berkeley UNIX.

13.7.2.1 BSD Regular Expression Compiling
.........................................

   With Berkeley UNIX, you can only search for a given regular
expression; you can't match one.  To search for it, you must first
compile it.  Before you compile it, you must indicate the regular
expression syntax you want it compiled according to by setting the
variable `re_syntax_options' (declared in `regex.h' to some syntax
(*note Regular Expression Syntax::).

   To compile a regular expression use:

     char *
     re_comp (char *REGEX)

REGEX is the address of a null-terminated regular expression.
`re_comp' uses an internal pattern buffer, so you can use only the most
recently compiled pattern buffer.  This means that if you want to use a
given regular expression that you've already compiled--but it isn't the
latest one you've compiled--you'll have to recompile it.  If you call
`re_comp' with the null string (_not_ the empty string) as the
argument, it doesn't change the contents of the pattern buffer.

   If `re_comp' successfully compiles the regular expression, it
returns zero.  If it can't compile the regular expression, it returns
an error string.  `re_comp''s error messages are identical to those of
`re_compile_pattern' (*note GNU Regular Expression Compiling::).

13.7.2.2 BSD Searching
......................

   Searching the Berkeley UNIX way means searching in a string starting
at its first character and trying successive positions within it to
find a match.  Once you've compiled a pattern using `re_comp' (*note
BSD Regular Expression Compiling::), you can ask Regex to search for
that pattern in a string using:

     int
     re_exec (char *STRING)

STRING is the address of the null-terminated string in which you want
to search.

   `re_exec' returns either 1 for success or 0 for failure.  It
automatically uses a GNU fastmap (*note Searching with Fastmaps::).

File: gnulib.info,  Node: awk regular expression syntax,  Next: egrep regular expression syntax,  Up: Regular expression syntaxes

13.8.1 `awk' regular expression syntax
--------------------------------------

   The character `.' matches any single character except the null
character.

`+'
     indicates that the regular expression should match one or more
     occurrences of the previous atom or regexp.

`?'
     indicates that the regular expression should match zero or one
     occurrence of the previous atom or regexp.

`\+'
     matches a `+'

`\?'
     matches a `?'.

   Bracket expressions are used to match ranges of characters.  Bracket
expressions where the range is backward, for example `[z-a]', are
invalid.  Within square brackets, `\' can be used to quote the
following character.  Character classes are not supported, so for
example you would need to use `[0-9]' instead of `[[:digit:]]'.

   GNU extensions are not supported and so `\w', `\W', `\<', `\>',
`\b', `\B', `\`', and `\'' match `w', `W', `<', `>', `b', `B', ``', and
`'' respectively.

   Grouping is performed with parentheses `()'.  An unmatched `)'
matches just itself.  A backslash followed by a digit matches that
digit.

   The alternation operator is `|'.

   The characters `^' and `$' always represent the beginning and end of
a string respectively, except within square brackets.  Within brackets,
`^' can be used to invert the membership of the character class being
specified.

   `*', `+' and `?' are special at any point in a regular expression
except:
  1. At the beginning of a regular expression

  2. After an open-group, signified by `('

  3. After the alternation operator `|'


   The longest possible match is returned; this applies to the regular
expression as a whole and (subject to this constraint) to
subexpressions within groups.

13.8.2 `egrep' regular expression syntax
----------------------------------------

   The character `.' matches any single character except newline.

`+'
     indicates that the regular expression should match one or more
     occurrences of the previous atom or regexp.

`?'
     indicates that the regular expression should match zero or one
     occurrence of the previous atom or regexp.

`\+'
     matches a `+'

`\?'
     matches a `?'.

   Bracket expressions are used to match ranges of characters.  Bracket
expressions where the range is backward, for example `[z-a]', are
ignored.  Within square brackets, `\' is taken literally.  Character
classes are supported; for example `[[:digit:]]' will match a single
decimal digit.  Non-matching lists `[^...]' do not ever match newline.

   GNU extensions are supported:
  1. `\w' matches a character within a word

  2. `\W' matches a character which is not within a word

  3. `\<' matches the beginning of a word

  4. `\>' matches the end of a word

  5. `\b' matches a word boundary

  6. `\B' matches characters which are not a word boundary

  7. `\`' matches the beginning of the whole input

  8. `\'' matches the end of the whole input


   Grouping is performed with parentheses `()'.  A backslash followed
by a digit acts as a back-reference and matches the same thing as the
previous grouped expression indicated by that number.  For example `\2'
matches the second group expression.  The order of group expressions is
determined by the position of their opening parenthesis `('.

   The alternation operator is `|'.

   The characters `^' and `$' always represent the beginning and end of
a string respectively, except within square brackets.  Within brackets,
`^' can be used to invert the membership of the character class being
specified.

   The characters `*', `+' and `?' are special anywhere in a regular
expression.

   The longest possible match is returned; this applies to the regular

   Grouping is performed with backslashes followed by parentheses `\(',
`\)'.  A backslash followed by a digit acts as a back-reference and
matches the same thing as the previous grouped expression indicated by
that number.  For example `\2' matches the second group expression.
The order of group expressions is determined by the position of their
opening parenthesis `\('.

   The alternation operator is `\|'.

   The character `^' only represents the beginning of a string when it
appears:
  1. At the beginning of a regular expression

  2. After an open-group, signified by `\('

  3. After the alternation operator `\|'


   The character `$' only represents the end of a string when it
appears:
  1. At the end of a regular expression

  2. Before a close-group, signified by `\)'

  3. Before the alternation operator `\|'


   `\*', `\+' and `\?' are special at any point in a regular expression

  3. After the alternation operator `\|'


   The character `$' only represents the end of a string when it
appears:
  1. At the end of a regular expression

  2. Before a close-group, signified by `\)'

  3. Before the alternation operator `\|'


   `*', `+' and `?' are special at any point in a regular expression
except:
  1. At the beginning of a regular expression

  2. After an open-group, signified by `\('

  3. After the alternation operator `\|'


   The longest possible match is returned; this applies to the regular
expression as a whole and (subject to this constraint) to
subexpressions within groups.

13.8.5 `gnu-awk' regular expression syntax
------------------------------------------

   The character `.' matches any single character.

`+'
     indicates that the regular expression should match one or more
     occurrences of the previous atom or regexp.

`?'
     indicates that the regular expression should match zero or one
     occurrence of the previous atom or regexp.

`\+'
     matches a `+'

`\?'
     matches a `?'.

   Bracket expressions are used to match ranges of characters.  Bracket
expressions where the range is backward, for example `[z-a]', are
invalid.  Within square brackets, `\' can be used to quote the
following character.  Character classes are supported; for example
`[[:digit:]]' will match a single decimal digit.

   GNU extensions are supported:
  1. `\w' matches a character within a word

  2. `\W' matches a character which is not within a word

  3. `\<' matches the beginning of a word

  4. `\>' matches the end of a word

  5. `\b' matches a word boundary

  6. `\B' matches characters which are not a word boundary

  7. `\`' matches the beginning of the whole input

  8. `\'' matches the end of the whole input


   Grouping is performed with parentheses `()'.  An unmatched `)'
matches just itself.  A backslash followed by a digit acts as a
back-reference and matches the same thing as the previous grouped
expression indicated by that number.  For example `\2' matches the
second group expression.  The order of group expressions is determined
by the position of their opening parenthesis `('.

   The alternation operator is `|'.

   The characters `^' and `$' always represent the beginning and end of
a string respectively, except within square brackets.  Within brackets,
`^' can be used to invert the membership of the character class being
specified.

   `*', `+' and `?' are special at any point in a regular expression
except:
  1. At the beginning of a regular expression

  2. After an open-group, signified by `('

  3. After the alternation operator `|'


   The longest possible match is returned; this applies to the regular
expression as a whole and (subject to this constraint) to
subexpressions within groups.

13.8.6 `grep' regular expression syntax
---------------------------------------

   The character `.' matches any single character except newline.

`\+'
     indicates that the regular expression should match one or more
     occurrences of the previous atom or regexp.

`\?'
     indicates that the regular expression should match zero or one
     occurrence of the previous atom or regexp.

`+ and ?'
     match themselves.

   Bracket expressions are used to match ranges of characters.  Bracket
expressions where the range is backward, for example `[z-a]', are
ignored.  Within square brackets, `\' is taken literally.  Character
classes are supported; for example `[[:digit:]]' will match a single
decimal digit.  Non-matching lists `[^...]' do not ever match newline.

   GNU extensions are supported:
  1. `\w' matches a character within a word

  2. `\W' matches a character which is not within a word

  3. `\<' matches the beginning of a word

  4. `\>' matches the end of a word

  5. `\b' matches a word boundary

  6. `\B' matches characters which are not a word boundary

  7. `\`' matches the beginning of the whole input

  8. `\'' matches the end of the whole input


   Grouping is performed with backslashes followed by parentheses `\(',
`\)'.  A backslash followed by a digit acts as a back-reference and
matches the same thing as the previous grouped expression indicated by
that number.  For example `\2' matches the second group expression.
The order of group expressions is determined by the position of their
opening parenthesis `\('.

   The alternation operator is `\|'.

   The character `^' only represents the beginning of a string when it
appears:
  1. At the beginning of a regular expression

  2. After an open-group, signified by `\('

  3. After a newline

  4. After the alternation operator `\|'


   The character `$' only represents the end of a string when it
appears:
  1. At the end of a regular expression

  2. Before a close-group, signified by `\)'

  3. Before a newline

  4. Before the alternation operator `\|'


   `\*', `\+' and `\?' are special at any point in a regular expression
except:
  1. At the beginning of a regular expression

  2. After an open-group, signified by `\('

  3. After a newline

  4. After the alternation operator `\|'


   Intervals are specified by `\{' and `\}'.  Invalid intervals such as
`a\{1z' are not accepted.

   The longest possible match is returned; this applies to the regular
expression as a whole and (subject to this constraint) to
subexpressions within groups.

     occurrences of the previous atom or regexp.

`?'
     indicates that the regular expression should match zero or one
     occurrence of the previous atom or regexp.

`\+'
     matches a `+'

`\?'
     matches a `?'.

   Bracket expressions are used to match ranges of characters.  Bracket
expressions where the range is backward, for example `[z-a]', are
invalid.  Within square brackets, `\' can be used to quote the
following character.  Character classes are supported; for example
`[[:digit:]]' will match a single decimal digit.

   GNU extensions are not supported and so `\w', `\W', `\<', `\>',
`\b', `\B', `\`', and `\'' match `w', `W', `<', `>', `b', `B', ``', and
`'' respectively.

   Grouping is performed with parentheses `()'.  An unmatched `)'
matches just itself.  A backslash followed by a digit acts as a
back-reference and matches the same thing as the previous grouped
expression indicated by that number.  For example `\2' matches the
second group expression.  The order of group expressions is determined
by the position of their opening parenthesis `('.

   The alternation operator is `|'.

   The characters `^' and `$' always represent the beginning and end of
a string respectively, except within square brackets.  Within brackets,
`^' can be used to invert the membership of the character class being
specified.

   `*', `+' and `?' are special at any point in a regular expression
except the following places, where they are not allowed:
  1. At the beginning of a regular expression

  2. After an open-group, signified by `('

  3. After the alternation operator `|'


   Intervals are specified by `{' and `}'.  Invalid intervals such as
`a{1z' are not accepted.

   The longest possible match is returned; this applies to the regular

Appendix A GNU Free Documentation License
*****************************************

                     Version 1.3, 3 November 2008

     Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
     `http://fsf.org/'

     Everyone is permitted to copy and distribute verbatim copies
     of this license document, but changing it is not allowed.

  0. PREAMBLE

     The purpose of this License is to make a manual, textbook, or other
     functional and useful document "free" in the sense of freedom: to
     assure everyone the effective freedom to copy and redistribute it,
     with or without modifying it, either commercially or
     noncommercially.  Secondarily, this License preserves for the
     author and publisher a way to get credit for their work, while not
     being considered responsible for modifications made by others.

     This License is a kind of "copyleft", which means that derivative
     works of the document must themselves be free in the same sense.
     It complements the GNU General Public License, which is a copyleft
     license designed for free software.

     We have designed this License in order to use it for manuals for
     free software, because free software needs free documentation: a
     free program should come with manuals providing the same freedoms
     that the software does.  But this License is not limited to
     software manuals; it can be used for any textual work, regardless
     of subject matter or whether it is published as a printed book.
     We recommend this License principally for works whose purpose is
     instruction or reference.

  1. APPLICABILITY AND DEFINITIONS

     This License applies to any manual or other work, in any medium,
     that contains a notice placed by the copyright holder saying it
     can be distributed under the terms of this License.  Such a notice
     grants a world-wide, royalty-free license, unlimited in duration,
     to use that work under the conditions stated herein.  The
     "Document", below, refers to any such manual or work.  Any member
     of the public is a licensee, and is addressed as "you".  You
     accept the license if you copy, modify or distribute the work in a
     way requiring permission under copyright law.

     A "Modified Version" of the Document means any work containing the
     Document or a portion of it, either copied verbatim, or with
     modifications and/or translated into another language.

     A "Secondary Section" is a named appendix or a front-matter section
     of the Document that deals exclusively with the relationship of the
     publishers or authors of the Document to the Document's overall
     subject (or to related matters) and contains nothing that could
     fall directly within that overall subject.  (Thus, if the Document
     is in part a textbook of mathematics, a Secondary Section may not
     explain any mathematics.)  The relationship could be a matter of
     historical connection with the subject or with related matters, or
     of legal, commercial, philosophical, ethical or political position
     regarding them.

     The "Invariant Sections" are certain Secondary Sections whose
     titles are designated, as being those of Invariant Sections, in
     the notice that says that the Document is released under this
     License.  If a section does not fit the above definition of
     Secondary then it is not allowed to be designated as Invariant.
     The Document may contain zero Invariant Sections.  If the Document
     does not identify any Invariant Sections then there are none.

     The "Cover Texts" are certain short passages of text that are
     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
     that says that the Document is released under this License.  A
     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
     be at most 25 words.

     A "Transparent" copy of the Document means a machine-readable copy,
     represented in a format whose specification is available to the
     general public, that is suitable for revising the document
     straightforwardly with generic text editors or (for images
     composed of pixels) generic paint programs or (for drawings) some
     widely available drawing editor, and that is suitable for input to
     text formatters or for automatic translation to a variety of
     formats suitable for input to text formatters.  A copy made in an
     otherwise Transparent file format whose markup, or absence of
     markup, has been arranged to thwart or discourage subsequent
     modification by readers is not Transparent.  An image format is
     not Transparent if used for any substantial amount of text.  A
     copy that is not "Transparent" is called "Opaque".

     Examples of suitable formats for Transparent copies include plain
     ASCII without markup, Texinfo input format, LaTeX input format,
     SGML or XML using a publicly available DTD, and
     standard-conforming simple HTML, PostScript or PDF designed for
     human modification.  Examples of transparent image formats include
     PNG, XCF and JPG.  Opaque formats include proprietary formats that
     can be read and edited only by proprietary word processors, SGML or
     XML for which the DTD and/or processing tools are not generally
     available, and the machine-generated HTML, PostScript or PDF
     produced by some word processors for output purposes only.

     The "Title Page" means, for a printed book, the title page itself,
     plus such following pages as are needed to hold, legibly, the
     material this License requires to appear in the title page.  For
     works in formats which do not have any title page as such, "Title
     Page" means the text near the most prominent appearance of the
     work's title, preceding the beginning of the body of the text.

     The "publisher" means any person or entity that distributes copies
     of the Document to the public.

     A section "Entitled XYZ" means a named subunit of the Document
     whose title either is precisely XYZ or contains XYZ in parentheses
     following text that translates XYZ in another language.  (Here XYZ
     stands for a specific section name mentioned below, such as
     "Acknowledgements", "Dedications", "Endorsements", or "History".)
     To "Preserve the Title" of such a section when you modify the
     Document means that it remains a section "Entitled XYZ" according
     to this definition.

     The Document may include Warranty Disclaimers next to the notice
     which states that this License applies to the Document.  These
     Warranty Disclaimers are considered to be included by reference in
     this License, but only as regards disclaiming warranties: any other
     implication that these Warranty Disclaimers may have is void and
     has no effect on the meaning of this License.

  2. VERBATIM COPYING

     You may copy and distribute the Document in any medium, either
     commercially or noncommercially, provided that this License, the
     copyright notices, and the license notice saying this License
     applies to the Document are reproduced in all copies, and that you
     add no other conditions whatsoever to those of this License.  You
     may not use technical measures to obstruct or control the reading
     or further copying of the copies you make or distribute.  However,
     you may accept compensation in exchange for copies.  If you
     distribute a large enough number of copies you must also follow
     the conditions in section 3.

     You may also lend copies, under the same conditions stated above,
     and you may publicly display copies.

  3. COPYING IN QUANTITY

     If you publish printed copies (or copies in media that commonly
     have printed covers) of the Document, numbering more than 100, and
     the Document's license notice requires Cover Texts, you must
     enclose the copies in covers that carry, clearly and legibly, all
     these Cover Texts: Front-Cover Texts on the front cover, and
     Back-Cover Texts on the back cover.  Both covers must also clearly
     and legibly identify you as the publisher of these copies.  The
     front cover must present the full title with all words of the
     title equally prominent and visible.  You may add other material
     on the covers in addition.  Copying with changes limited to the
     covers, as long as they preserve the title of the Document and
     satisfy these conditions, can be treated as verbatim copying in
     other respects.

     If the required texts for either cover are too voluminous to fit
     legibly, you should put the first ones listed (as many as fit
     reasonably) on the actual cover, and continue the rest onto
     adjacent pages.

     If you publish or distribute Opaque copies of the Document
     numbering more than 100, you must either include a
     machine-readable Transparent copy along with each Opaque copy, or
     state in or with each Opaque copy a computer-network location from
     which the general network-using public has access to download
     using public-standard network protocols a complete Transparent
     copy of the Document, free of added material.  If you use the
     latter option, you must take reasonably prudent steps, when you
     begin distribution of Opaque copies in quantity, to ensure that
     this Transparent copy will remain thus accessible at the stated
     location until at least one year after the last time you
     distribute an Opaque copy (directly or through your agents or
     retailers) of that edition to the public.

     It is requested, but not required, that you contact the authors of
     the Document well before redistributing any large number of
     copies, to give them a chance to provide you with an updated
     version of the Document.

  4. MODIFICATIONS

     You may copy and distribute a Modified Version of the Document
     under the conditions of sections 2 and 3 above, provided that you
     release the Modified Version under precisely this License, with
     the Modified Version filling the role of the Document, thus
     licensing distribution and modification of the Modified Version to
     whoever possesses a copy of it.  In addition, you must do these
     things in the Modified Version:

       A. Use in the Title Page (and on the covers, if any) a title
          distinct from that of the Document, and from those of
          previous versions (which should, if there were any, be listed
          in the History section of the Document).  You may use the
          same title as a previous version if the original publisher of
          that version gives permission.

       B. List on the Title Page, as authors, one or more persons or
          entities responsible for authorship of the modifications in
          the Modified Version, together with at least five of the
          principal authors of the Document (all of its principal
          authors, if it has fewer than five), unless they release you
          from this requirement.

       C. State on the Title page the name of the publisher of the
          Modified Version, as the publisher.

       D. Preserve all the copyright notices of the Document.

       E. Add an appropriate copyright notice for your modifications
          adjacent to the other copyright notices.

       F. Include, immediately after the copyright notices, a license
          notice giving the public permission to use the Modified
          Version under the terms of this License, in the form shown in
          the Addendum below.

       G. Preserve in that license notice the full lists of Invariant
          Sections and required Cover Texts given in the Document's
          license notice.

       H. Include an unaltered copy of this License.

       I. Preserve the section Entitled "History", Preserve its Title,
          and add to it an item stating at least the title, year, new
          authors, and publisher of the Modified Version as given on
          the Title Page.  If there is no section Entitled "History" in
          the Document, create one stating the title, year, authors,
          and publisher of the Document as given on its Title Page,
          then add an item describing the Modified Version as stated in
          the previous sentence.

       J. Preserve the network location, if any, given in the Document
          for public access to a Transparent copy of the Document, and
          likewise the network locations given in the Document for
          previous versions it was based on.  These may be placed in
          the "History" section.  You may omit a network location for a
          work that was published at least four years before the
          Document itself, or if the original publisher of the version
          it refers to gives permission.

       K. For any section Entitled "Acknowledgements" or "Dedications",
          Preserve the Title of the section, and preserve in the
          section all the substance and tone of each of the contributor
          acknowledgements and/or dedications given therein.

       L. Preserve all the Invariant Sections of the Document,
          unaltered in their text and in their titles.  Section numbers
          or the equivalent are not considered part of the section
          titles.

       M. Delete any section Entitled "Endorsements".  Such a section
          may not be included in the Modified Version.

       N. Do not retitle any existing section to be Entitled
          "Endorsements" or to conflict in title with any Invariant
          Section.

       O. Preserve any Warranty Disclaimers.

     If the Modified Version includes new front-matter sections or
     appendices that qualify as Secondary Sections and contain no
     material copied from the Document, you may at your option
     designate some or all of these sections as invariant.  To do this,
     add their titles to the list of Invariant Sections in the Modified
     Version's license notice.  These titles must be distinct from any
     other section titles.

     You may add a section Entitled "Endorsements", provided it contains
     nothing but endorsements of your Modified Version by various
     parties--for example, statements of peer review or that the text
     has been approved by an organization as the authoritative
     definition of a standard.

     You may add a passage of up to five words as a Front-Cover Text,
     and a passage of up to 25 words as a Back-Cover Text, to the end
     of the list of Cover Texts in the Modified Version.  Only one
     passage of Front-Cover Text and one of Back-Cover Text may be
     added by (or through arrangements made by) any one entity.  If the
     Document already includes a cover text for the same cover,
     previously added by you or by arrangement made by the same entity
     you are acting on behalf of, you may not add another; but you may
     replace the old one, on explicit permission from the previous
     publisher that added the old one.

     The author(s) and publisher(s) of the Document do not by this
     License give permission to use their names for publicity for or to
     assert or imply endorsement of any Modified Version.

  5. COMBINING DOCUMENTS

     You may combine the Document with other documents released under
     this License, under the terms defined in section 4 above for
     modified versions, provided that you include in the combination
     all of the Invariant Sections of all of the original documents,
     unmodified, and list them all as Invariant Sections of your
     combined work in its license notice, and that you preserve all
     their Warranty Disclaimers.

     The combined work need only contain one copy of this License, and
     multiple identical Invariant Sections may be replaced with a single
     copy.  If there are multiple Invariant Sections with the same name
     but different contents, make the title of each such section unique
     by adding at the end of it, in parentheses, the name of the
     original author or publisher of that section if known, or else a
     unique number.  Make the same adjustment to the section titles in
     the list of Invariant Sections in the license notice of the
     combined work.

     In the combination, you must combine any sections Entitled
     "History" in the various original documents, forming one section
     Entitled "History"; likewise combine any sections Entitled
     "Acknowledgements", and any sections Entitled "Dedications".  You
     must delete all sections Entitled "Endorsements."

  6. COLLECTIONS OF DOCUMENTS

     You may make a collection consisting of the Document and other
     documents released under this License, and replace the individual
     copies of this License in the various documents with a single copy
     that is included in the collection, provided that you follow the
     rules of this License for verbatim copying of each of the
     documents in all other respects.

     You may extract a single document from such a collection, and
     distribute it individually under this License, provided you insert
     a copy of this License into the extracted document, and follow
     this License in all other respects regarding verbatim copying of
     that document.

  7. AGGREGATION WITH INDEPENDENT WORKS

     A compilation of the Document or its derivatives with other
     separate and independent documents or works, in or on a volume of
     a storage or distribution medium, is called an "aggregate" if the
     copyright resulting from the compilation is not used to limit the
     legal rights of the compilation's users beyond what the individual
     works permit.  When the Document is included in an aggregate, this
     License does not apply to the other works in the aggregate which
     are not themselves derivative works of the Document.

     If the Cover Text requirement of section 3 is applicable to these
     copies of the Document, then if the Document is less than one half
     of the entire aggregate, the Document's Cover Texts may be placed
     on covers that bracket the Document within the aggregate, or the
     electronic equivalent of covers if the Document is in electronic
     form.  Otherwise they must appear on printed covers that bracket
     the whole aggregate.

  8. TRANSLATION

     Translation is considered a kind of modification, so you may
     distribute translations of the Document under the terms of section
     4.  Replacing Invariant Sections with translations requires special
     permission from their copyright holders, but you may include
     translations of some or all Invariant Sections in addition to the
     original versions of these Invariant Sections.  You may include a
     translation of this License, and all the license notices in the
     Document, and any Warranty Disclaimers, provided that you also
     include the original English version of this License and the
     original versions of those notices and disclaimers.  In case of a
     disagreement between the translation and the original version of
     this License or a notice or disclaimer, the original version will
     prevail.

     If a section in the Document is Entitled "Acknowledgements",
     "Dedications", or "History", the requirement (section 4) to
     Preserve its Title (section 1) will typically require changing the
     actual title.

  9. TERMINATION

     You may not copy, modify, sublicense, or distribute the Document
     except as expressly provided under this License.  Any attempt
     otherwise to copy, modify, sublicense, or distribute it is void,
     and will automatically terminate your rights under this License.

     However, if you cease all violation of this License, then your
     license from a particular copyright holder is reinstated (a)
     provisionally, unless and until the copyright holder explicitly
     and finally terminates your license, and (b) permanently, if the
     copyright holder fails to notify you of the violation by some
     reasonable means prior to 60 days after the cessation.

     Moreover, your license from a particular copyright holder is
     reinstated permanently if the copyright holder notifies you of the
     violation by some reasonable means, this is the first time you have
     received notice of violation of this License (for any work) from
     that copyright holder, and you cure the violation prior to 30 days
     after your receipt of the notice.

     Termination of your rights under this section does not terminate
     the licenses of parties who have received copies or rights from
     you under this License.  If your rights have been terminated and
     not permanently reinstated, receipt of a copy of some or all of
     the same material does not give you any rights to use it.

 10. FUTURE REVISIONS OF THIS LICENSE

     The Free Software Foundation may publish new, revised versions of
     the GNU Free Documentation License from time to time.  Such new
     versions will be similar in spirit to the present version, but may
     differ in detail to address new problems or concerns.  See
     `http://www.gnu.org/copyleft/'.

     Each version of the License is given a distinguishing version
     number.  If the Document specifies that a particular numbered
     version of this License "or any later version" applies to it, you
     have the option of following the terms and conditions either of
     that specified version or of any later version that has been
     published (not as a draft) by the Free Software Foundation.  If
     the Document does not specify a version number of this License,
     you may choose any version ever published (not as a draft) by the
     Free Software Foundation.  If the Document specifies that a proxy
     can decide which future versions of this License can be used, that
     proxy's public statement of acceptance of a version permanently
     authorizes you to choose that version for the Document.

 11. RELICENSING

     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
     World Wide Web server that publishes copyrightable works and also
     provides prominent facilities for anybody to edit those works.  A
     public wiki that anybody can edit is an example of such a server.
     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
     site means any set of copyrightable works thus published on the MMC
     site.

     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
     license published by Creative Commons Corporation, a not-for-profit
     corporation with a principal place of business in San Francisco,
     California, as well as future copyleft versions of that license
     published by that same organization.

     "Incorporate" means to publish or republish a Document, in whole or
     in part, as part of another Document.

     An MMC is "eligible for relicensing" if it is licensed under this
     License, and if all works that were first published under this
     License somewhere other than this MMC, and subsequently
     incorporated in whole or in part into the MMC, (1) had no cover
     texts or invariant sections, and (2) were thus incorporated prior
     to November 1, 2008.

     The operator of an MMC Site may republish an MMC contained in the
     site under CC-BY-SA on the same site at any time before August 1,
     2009, provided the MMC is eligible for relicensing.


ADDENDUM: How to use this License for your documents
====================================================

   To use this License in a document you have written, include a copy of
the License in the document and put the following copyright and license
notices just after the title page:

       Copyright (C)  YEAR  YOUR NAME.
       Permission is granted to copy, distribute and/or modify this document
       under the terms of the GNU Free Documentation License, Version 1.3
       or any later version published by the Free Software Foundation;
       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
       Texts.  A copy of the license is included in the section entitled ``GNU
       Free Documentation License''.

   If you have Invariant Sections, Front-Cover Texts and Back-Cover
Texts, replace the "with...Texts." line with this:

         with the Invariant Sections being LIST THEIR TITLES, with
         the Front-Cover Texts being LIST, and with the Back-Cover Texts
         being LIST.

   If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the
situation.

   If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of
free software license, such as the GNU General Public License, to
permit their use in free software.
