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.</td></table>
<table width="100%" border=0 rules="none" frame="void"
cols="2" cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="10%"></td><td width="90%">
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.</td></table>

<tr valign="top" align="left">
<td width="10%"></td><td width="90%">
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.</td></table>

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.</td></table>
