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 mes-
       sage 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,  nget-
       text  functions, and by the dgettext, dcgettext, dngettext
       and dcngettext functions when called with a  NULL  domain-
       name argument.

       If  domainname  is not NULL, the current message domain is
       set to domainname. The string the function  stores  inter-
       nally 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.
