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
       available.   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, POSIX.1-2008.

NOTES

       The catgets() function is 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
       possible error returns seem to be discarded in SUSv2 in favor of always returning message.
