<em class="parameter"><code><a href="/usr/share/gtk-doc/html/glib/glib-Error-Reporting.html#GError"><span class="type">GError</span></a> **error</code></em>);</pre>
<p>Finds the base domain for a given <em class="parameter"><code>hostname</code></em>
. The base domain is
composed by the top level domain (such as .org, .com, .co.uk, etc)
plus the second level domain, for example for myhost.mydomain.com
it will return mydomain.com.</p>
<p>Note that <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> will be returned for private URLs (those not ending
with any well known TLD) because choosing a base domain for them
would be totally arbitrary.</p>
<p>This method only works for valid UTF-8 hostnames in their canonical
representation form, so you should use <a href="/usr/share/gtk-doc/html/glib/glib-Hostname-Utilities.html#g-hostname-to-unicode"><code class="function">g_hostname_to_unicode()</code></a> to
get the canonical representation if that is not the case.</p>
