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
   domainname.  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
   warnings in C code predating ANSI C.
