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.

       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.
