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.
