<p>A <a class="link" href="InfCommunicationObject.html" title="InfCommunicationObject"><span class="type">InfCommunicationObject</span></a> is the destination of network messages sent
through the <a class="link" href="InfCommunicationManager.html" title="InfCommunicationManager"><span class="type">InfCommunicationManager</span></a>. Each <a class="link" href="InfCommunicationGroup.html" title="InfCommunicationGroup"><span class="type">InfCommunicationGroup</span></a> is
associated with <a class="link" href="InfCommunicationObject.html" title="InfCommunicationObject"><span class="type">InfCommunicationObject</span></a>. Requests received by that group
are reported to the <a class="link" href="InfCommunicationObject.html" title="InfCommunicationObject"><span class="type">InfCommunicationObject</span></a> by calling
<a class="link" href="InfCommunicationObject.html#inf-communication-object-received" title="inf_communication_object_received ()"><code class="function">inf_communication_object_received()</code></a> on it. Messages sent to a member of
that group (via <a class="link" href="InfCommunicationGroup.html#inf-communication-group-send-message" title="inf_communication_group_send_message ()"><code class="function">inf_communication_group_send_message()</code></a>) are also reported
by calling <a class="link" href="InfCommunicationObject.html#inf-communication-object-sent" title="inf_communication_object_sent ()"><code class="function">inf_communication_object_sent()</code></a>.</p>

<em class="parameter"><code><a class="link" href="InfXmlConnection.html" title="InfXmlConnection"><span class="type">InfXmlConnection</span></a> *conn</code></em>,
<em class="parameter"><code><span class="type">xmlNodePtr</span> node</code></em>);</pre>
<p>This function is called when a <a class="link" href="InfCommunicationManager.html" title="InfCommunicationManager"><span class="type">InfCommunicationManager</span></a> received data from
<em class="parameter"><code>connection</code></em>
belonging to a group whose communication object is <em class="parameter"><code>object</code></em>
.
This function should process the incoming data. If it could not process it,
then it should set <em class="parameter"><code>error</code></em>
.</p>
<p>It should return <a class="link" href="InfCommunicationObject.html#INF-COMMUNICATION-SCOPE-GROUP:CAPS"><code class="literal">INF_COMMUNICATION_SCOPE_GROUP</code></a> if the message is allowed
to be forwarded to other group members. Since recipients of forwarded
messages don't see the original sender (but just the forwarding host),
forwarding arbitrary messages could lead to a security problem in the worst
case.</p>
<p>For example, if, in central mode, a client sends an (invalid)
<add-node> request to the whole (InfDirectory) group, and the server
forwarded this to all clients, those clients would try to create a new node
although the server rejected the request. In decentral mode, this is not a
problem since all clients see where the message comes from, and can
themselves reject all messages not coming from the server.</p>
