BIND_TEXTDOMAIN_CODESET(3) Library Functions Manual BIND_TEXTDOMAIN_CODESET(3)
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_lang-
info (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 domain-
name 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 warn-
ings in C code predating ANSI C.
