A message domain is a set of translatable <i>msgid</i>
messages. Usually, every software package has its own
message domain.</td></table>

By default, the <b>gettext</b> family of functions returns
translated messages in the locale's character encoding,
which can be retrieved as <b>nl_langinfo(CODESET)</b>. The
need for calling <b>bind_textdomain_codeset</b> 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.</td></table>

If <i>codeset</i> is not NULL, it must be a valid encoding
name which can be used for the <b>iconv_open</b> function.
The <b>bind_textdomain_codeset</b> function sets the output
codeset for message catalogs belonging to domain
<i>domainname</i> to <i>codeset</i>. The function makes
copies of the argument strings as needed.</td></table>

<tr valign="top" align="left">
<td width="10%"></td><td width="90%">
If <i>codeset</i> is NULL, the function returns the
previously set codeset for domain <i>domainname</i>. The
default is NULL, denoting the locale's character
encoding.</td></table>

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