<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">textdomain
− set domain for future gettext() calls</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 *
textdomain (const char *</b> <i>domainname</i><b>);</b></p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
<b>textdomain</b> function sets or retrieves the current
message domain.</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.
The domain name is used to determine the message catalog
where a translation is looked up; it must be a non-empty
string.</p>
<p style="margin-left:11%; margin-top: 1em">The current
message domain is used by the <b>gettext</b>,
<b>ngettext</b> functions, and by the <b>dgettext</b>,
<b>dcgettext</b>, <b>dngettext</b> and <b>dcngettext</b>
functions when called with a NULL domainname argument.</p>
<p style="margin-left:11%; margin-top: 1em">If
<i>domainname</i> is not NULL, the current message domain is
set to <i>domainname</i>. The string the function stores
internally is a copy of the <i>domainname</i> argument.</p>
<p style="margin-left:11%; margin-top: 1em">If
<i>domainname</i> is NULL, the function returns the current
message domain.</p>
<h2>RETURN VALUE
<a name="RETURN VALUE"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">If successful,
the <b>textdomain</b> function returns the current message
domain, after possibly changing it. The resulting string is
valid until the next <b>textdomain</b> call 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.</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>
