<p>Client channel factories are used to create channel proxies. An application
wanting to use its own <a class="link" href="telepathy-glib-channel.html#TpChannel"><span class="type">TpChannel</span></a> subclass has to implement an object
implementing the <a class="link" href="telepathy-glib-client-channel-factory.html#TpClientChannelFactoryInterface" title="struct TpClientChannelFactoryInterface"><span class="type">TpClientChannelFactoryInterface</span></a> interface.</p>
<p>Once a channel has been created by a factory using

on it the channel features returned by
<a class="link" href="telepathy-glib-client-channel-factory.html#tp-client-channel-factory-dup-channel-features" title="tp_client_channel_factory_dup_channel_features ()"><code class="function">tp_client_channel_factory_dup_channel_features()</code></a> using
