CATGETS(3P)		   POSIX Programmer's Manual		   CATGETS(3P)

       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       catgets — read a program message

       #include <nl_types.h>

       char *catgets(nl_catd catd, int set_id, int msg_id, const char *s);

       The catgets() function shall attempt to read  message  msg_id,  in  set
       set_id, from the message catalog identified by catd.  The catd argument
       is a message catalog  descriptor	 returned  from	 an  earlier  call  to
       catopen().   The	 results are undefined if catd is not a value returned
       by catopen() for a message catalog still open in	 the  process.	The  s
       argument	 points to a default message string which shall be returned by
       catgets() if it cannot retrieve the identified message.

       The catgets() function need not be thread-safe.

       If the identified message is retrieved  successfully,  catgets()	 shall
       return  a pointer to an internal buffer area containing the null-termi‐
       nated message string. If the call is unsuccessful  for  any  reason,  s
       shall be returned and errno shall be set to indicate the error.

       The catgets() function shall fail if:

       EINTR  The  read	 operation was terminated due to the receipt of a sig‐
	      nal, and no data was transferred.

       ENOMSG The message identified by set_id and msg_id is not in  the  mes‐
	      sage catalog.

       The catgets() function may fail if:

       EBADF  The catd argument is not a valid message catalog descriptor open
	      for reading.

	      The message identified by set_id and  msg_id  in	the  specified
	      message  catalog did not satisfy implementation-defined security

       EINVAL The message catalog identified by catd is corrupted.
