PROLOG         top

       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.

NAME         top

       catgets — read a program message

SYNOPSIS         top

       #include <nl_types.h>

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

DESCRIPTION         top

       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.

RETURN VALUE         top

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

ERRORS         top

       The catgets() function shall fail if:

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

       ENOMSG The message identified by set_id and msg_id is not in the
              message 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 criteria.

       EINVAL The message catalog identified by catd is corrupted.
