<p style="margin-left:11%; margin-top: 1em">bind_textdomain_codeset
− set encoding of message translations</p>
<h2>SYNOPSIS
<a name="SYNOPSIS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>#include
<libintl.h></b></p>
<p style="margin-left:11%; margin-top: 1em"><b>char *
bind_textdomain_codeset (const char *</b>
<i>domainname</i><b>, <br>
const char *</b> <i>codeset</i><b>);</b></p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
<b>bind_textdomain_codeset</b> function sets the output
codeset for message catalogs for domain
<i>domainname</i>.</p>
<p style="margin-left:11%; margin-top: 1em">A message
domain is a set of translatable <i>msgid</i> messages.
Usually, every software package has its own message
domain.</p>
<p style="margin-left:11%; margin-top: 1em">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>
<p style="margin-left:11%; margin-top: 1em"><i>domainname</i>
must be a non-empty string.</p>
<p style="margin-left:11%; margin-top: 1em">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>
<p style="margin-left:11%; margin-top: 1em">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
<a name="RETURN VALUE"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">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>
<h2>ERRORS
<a name="ERRORS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The following
error can occur, among others:</p>
<table width="100%" border="0" rules="none" frame="void"
cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="11%"></td>
<td width="9%">
<p><b>ENOMEM</b></p></td>
<td width="2%"></td>
<td width="43%">
<p>Not enough memory available.</p></td>
<td width="35%">
</td></tr>
</table>
<h2>BUGS
<a name="BUGS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The return type
ought to be <b>const char *</b>, but is <b>char *</b> to
avoid warnings in C code predating ANSI C.</p>
