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.
