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 char‐
       acter 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.
