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, 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.

NAME

       bind_textdomain_codeset - set encoding of message translations

SYNOPSIS

       #include <libintl.h>

       char * bind_textdomain_codeset (const char * domainname,
				       const char * codeset);

DESCRIPTION

       The bind_textdomain_codeset function sets the output codeset for message catalogs for domain domainname.

       A message domain is a set of translatable msgid messages. Usually, every software package has its own message domain.

       By  default,  the  gettext  family  of  functions returns translated messages in the locale's character encoding, which can be retrieved as
       nl_langinfo(CODESET). The need for calling bind_textdomain_codeset arises for programs which store strings  in  a  locale  independent  way
       (e.g.  UTF-8) and want to avoid an extra character set conversion on the returned translated messages.

       domainname must be a non-empty string.

       If  codeset  is not NULL, it must be a valid encoding name which can be used for the iconv_open function. The bind_textdomain_codeset func-
       tion sets the output codeset for message catalogs belonging to domain domainname to codeset. The function  makes  copies  of  the  argument
       strings as needed.

       If codeset is NULL, the function returns the previously set codeset for domain domainname. The default is NULL, denoting the locale's char-
       acter encoding.

RETURN VALUE

       If successful, the bind_textdomain_codeset function returns the current codeset for domain domainname,  after  possibly	changing  it.  The
       resulting  string is valid until the next bind_textdomain_codeset call for the same domainname and must not be modified or freed. If a mem-
       ory allocation failure occurs, it sets errno to ENOMEM and returns NULL. If no codeset has been set for domain domainname, it 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.
