CATGETS(3)              NetBSD Library Functions Manual             CATGETS(3)


NAME

     catgets -- retrieve string from message catalog


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <nl_types.h>

     char *
     catgets(nl_catd catd, int set_id, int msg_id, const char *s);


DESCRIPTION

     The catgets() function attempts to retrieve message msg_id of set set_id
     from the message catalog referenced by the descriptor catd.  The argument
     s points to a default message which is returned if the function is unable
     to retrieve the specified message.


RETURN VALUES

     If the specified message was retrieved successfully, catgets() returns a
     pointer to an internal buffer containing the message string; otherwise it
     returns s.


ERRORS

     The catgets() function will fail if:

     [EBADF]            The catd argument is not a valid message catalog
                        descriptor open for reading.

     [EINTR]            The operation was interrupted by a signal.

     [ENOMSG]           The message identified by set_id and msg_id is not in
                        the message catalog.


SEE ALSO

     gencat(1), catclose(3), catopen(3), nls(7)


STANDARDS

     The catgets() function conforms to X/Open Portability Guide Issue 4,
     Version 2 (``XPG4.2'').

     Major Unix vendors are split over the adoption of the two most important
     message catalog specifications: catgets or gettext(3).  The primary con-
     cern with the catgets interface is that every translatable string has to
     define a number (or a symbolic constant) which must correspond to the
     message in the catalog.  Duplicate message IDs are not allowed.  Con-
     structing message catalogs is difficult.
