## Detailed Description

Define the interface for ACE_Log_Msg backend strategies.

The ACE_Log_Msg class can log to multiple backend strategies, for example, some send messages to a remote logger, others dump to a file, or simply to stderr. In the future we could define interfaces that log to the syslog daemon (on UNIX), the Event log (on NT) a temporary ring buffer, etc.

## Constructor & Destructor Documentation

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_Log_Msg_Backend::~ACE_Log_Msg_Backend | ( | void |  | ) | `[virtual]`

| No-op virtual destructor.

## Member Function Documentation

virtual int ACE_Log_Msg_Backend::close | ( | void |  | ) | `[pure virtual]`

| Close the backend completely. Implemented in ACE_Log_Msg_IPC, ACE_Log_Msg_NT_Event_Log, and ACE_Log_Msg_UNIX_Syslog.

virtual int ACE_Log_Msg_Backend::log | ( | ACE_Log_Record & | log_record | ) | `[pure virtual]`

| Backend routine. This is called when we want to log a message. Since this routine is pure virtual, it must be overwritten by the subclass. Implemented in ACE_Log_Msg_IPC, ACE_Log_Msg_NT_Event_Log, and ACE_Log_Msg_UNIX_Syslog.

virtual int ACE_Log_Msg_Backend::open | ( | const ACE_TCHAR * | logger_key | ) | `[pure virtual]`

| Open a new connection. Implemented in ACE_Log_Msg_IPC, ACE_Log_Msg_NT_Event_Log, and ACE_Log_Msg_UNIX_Syslog.

virtual int ACE_Log_Msg_Backend::reset | ( | void |  | ) | `[pure virtual]`

| Implemented in ACE_Log_Msg_IPC, ACE_Log_Msg_NT_Event_Log, and ACE_Log_Msg_UNIX_Syslog.
