CATGETS(3)                 Linux Programmer's Manual                CATGETS(3)
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 cur-
       rently 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 con-
       taining the null-terminated  message  string.   On  failure,  catgets()
       returns the value message.

CONFORMING TO

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.
