<p>If @net is NULL, then events will be monitored for any network. If @net is non-NULL, then only the specific network will be monitored.</p>
<p>Most types of event have a callback providing a custom set of parameters for the event.

<p>The <a href="libvirt-libvirt-network.html#virNetworkPtr">virNetworkPtr</a> object handle passed into the callback upon delivery of an event is only valid for the duration of execution of the callback. If the callback wishes to keep the network object after the callback returns, it shall take a reference to it, by calling <a href="libvirt-libvirt-network.html#virNetworkRef">virNetworkRef</a>(). The reference can be released once the object is no longer required by calling <a href="libvirt-libvirt-network.html#virNetworkFree">virNetworkFree</a>().</p>
<p>The return value from this method is a positive integer identifier for the callback. To unregister a callback, this callback ID should be passed to the <a href="libvirt-libvirt-network.html#virConnectNetworkEventDeregisterAny">virConnectNetworkEventDeregisterAny</a>() method.</p>
