NAME

       catgets - read a program message

SYNOPSIS

       #include <nl_types.h>

       char *catgets(nl_catd catd, int set_num, int msg_num, const char *s);

DESCRIPTION

       The catgets() function attempts to read message msg_num, in set set_num, from the message catalog identified by	catd. The catd argument is
       a catalog descriptor returned from an earlier call to  catopen(). The s argument points to a default message string which will be  returned
       by  catgets() if the identified message catalog is not currently available.

RETURN VALUES

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

ERRORS

       The catgets() function may fail if:

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

       EBADMSG	  The  number  of  %n  specifiers that appear in the message string specified by s does not match the number of %n specifiers that
		  appear in the message identified by set_id and msg_id in the specified message catalog.

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

       EINVAL	  The message catalog identified by catd is corrupted.

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

USAGE

       The catgets() function can be used safely in multithreaded applications as long as setlocale(3C) is not being called to change the locale.
