NAME         top

       catgets - get message from a message catalog

SYNOPSIS         top

       #include <nl_types.h>

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

DESCRIPTION         top

       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         top

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

NOTES         top

       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.
