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 
msgidmessages. 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 dcngettextfunctions 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 
domainnameargument.
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 
textdomaincall 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.
