<h2>DESCRIPTION</h2>
<!-- INDENTATION -->
<table width="100%" border=0 rules="none" frame="void"

<p>The <b>bind_textdomain_codeset</b> function sets the
output codeset for message catalogs for domain
<i>domainname</i>.</p>
<!-- INDENTATION -->
<p>A message domain is a set of translatable <i>msgid</i>
messages. Usually, every software package has its own
message domain.</p>
<!-- INDENTATION -->
<p>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.</p>
<!-- INDENTATION -->
<p><i>domainname</i> must be a non-empty string.</p>
<!-- INDENTATION -->
<p>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.</p>
<!-- INDENTATION -->
<p>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.</p>

<h2>RETURN VALUE</h2>

<td width="89%">
<p>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.</p>
