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.
