catgets - get message from a message catalog


   #include <nl_types.h>

   char *catgets(nl_catd catalog, int set_number, int message_number,
                 const char *message);


   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').


   On  success,  catgets()  returns  a  pointer to an internal buffer area
   containing the null-terminated message string.  On  failure,  catgets()
   returns the value message.

   The catgets() function is available only in  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.
