selector
    The selector, exactly as to be passed to the tcflush(3) system call.

RETURN VALUE
The explain_tcflush_or_die function only returns on success, see tcflush(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_tcflush_on_error function always returns the value return by the wrapped tcflush(3) system call.

    explain_tcflush_or_die(fildes, selector);
