Linux 2.6 - man page for catgets (linux section 3)

CATGETS(3)			    Linux Programmer's Manual			       CATGETS(3)

NAME
       catgets - get message from a message catalog

SYNOPSIS
       #include <nl_types.h>

       char *catgets(nl_catd catalog, int set_number, int message_number,
		     const char *message);

DESCRIPTION
       catgets()  reads  the  message message_number, in set set_number, from the message catalog
       identified by catalog, where catalog is a catalog descriptor returned from an earlier call
       to  catopen(3).	 The  fourth  argument, message, points to a default message string which
       will be returned by catgets() if the identified message catalog is  not	currently  avail-
       able.   The  message-text  is contained in an internal buffer area and should be copied by
       the application if it is to be saved or modified.  The return string is always  terminated
       with a null byte ('\0').

RETURN VALUE
       On  success,  catgets()	returns a pointer to an internal buffer area containing the null-
       terminated message string.  On failure, catgets() returns the value message.

CONFORMING TO
       POSIX.1-2001.

NOTES
       These functions are available only in libc.so.4.4.4c  and  above.   The	Jan  1987  X/Open
       Portability Guide specifies a more subtle error return: message is returned if the message
       catalog specified by catalog is not available, while an empty string is returned when  the
       message catalog is available but does not contain the specified message.  These two possi-
       ble error returns seem to be discarded in SUSv2 in favor of always returning message.
