TEXTDOMAIN(3) Library Functions Manual 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, dnget‐
text 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 allo‐
cation 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.
