textdomain(3)

NAME

       textdomain - set domain for future gettext() calls

SYNOPSIS

       #include <libintl.h>

       char * textdomain (const char * domainname);

DESCRIPTION

       The textdomain function sets or retrieves the current message domain.

       A  message  domain  is  a  set of translatable msgid messages. Usually,
       every software package has its own message domain. The domain  name  is
       used to determine the message catalog where a translation is looked up;
       it must be a non-empty string.

       The current message domain is used by the gettext, ngettext  functions,
       and by the dgettext, dcgettext, dngettext and dcngettext functions when
       called with a NULL domainname argument.

       If domainname is not NULL, the current message domain is set to domain-
       name.  The  string  the  function  stores  internally  is a copy of the
       domainname argument.

       If domainname is NULL, the function returns the current message domain.

RETURN VALUE

       If  successful,  the  textdomain  function  returns the current message
       domain, after possibly changing it. The resulting string is valid until
       the next textdomain call and must not be modified or freed. If a memory
       allocation failure occurs, it sets errno to ENOMEM and returns NULL.

ERRORS

       The following error can occur, among others:

       ENOMEM Not enough memory available.

BUGS

       The return type ought to be const char *, but is char * to avoid  warn-
       ings in C code predating ANSI C.
