<
dl>
<

b>oop_adns_new<
/b>
<
dd>Create a new liboop adns adapter. This adapter manages an instance of
<
a href="http://www.chiark.greenend.org.uk/~ian/adns/">Ian Jackson
's
asychronous DNS resolver</a> and supplies it with events from <em>source</em>.
The adns instance is initialized with the supplied <em>flags</em> and
<em>diag</em> file; refer to the adns documentation for details.<p>
If a malloc failure or other catastrophic system error occurs creating the
adapter, NULL is returned. The caller must handle this failure.<p>
<dt><b>oop_adns_delete</b>
<dd>Destroy the liboop adns adapter <em>adns</em>. This frees all resources
associated with the adapter, including the underlying adns instance. Any
callbacks registered with the event source are cancelled. The adapter can have
no active queries when it is deleted.<p>
