BIND_TEXTDOMAIN_CODESET(3)                  DragonFly Library Functions Manual


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 function
       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 character
       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 memory
       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.
