## Description

The TpSvcChannelDispatcher interface (auto-generated from the Telepathy spec) makes it easier to export an object implementing the Telepathy ChannelDispatcher interface, with the correct method and signal signatures, and emit signals from that object in a type-safe way.

Similarly, TpSvcChannelDispatcherInterfaceOperationList helps to implement the optional OperationList interface.

You don't need these interfaces unless you're implementing a Telepathy ChannelDispatcher, such as Mission Control.

## Details

### TpSvcChannelDispatcher

    typedef struct _TpSvcChannelDispatcher TpSvcChannelDispatcher;

Dummy typedef representing any implementation of this interface.

### TpSvcChannelDispatcherClass

    typedef struct _TpSvcChannelDispatcherClass TpSvcChannelDispatcherClass;

The class of TpSvcChannelDispatcher.

In a full implementation of this interface (i.e. all methods implemented), the interface initialization function used in `G_IMPLEMENT_INTERFACE()` would typically look like this:

    static void
    implement_channel_dispatcher (gpointer klass,
        gpointer unused G_GNUC_UNUSED)
    {
    #define IMPLEMENT(x) tp_svc_channel_dispatcher_implement_##x (\
      klass, my_object_##x)
      IMPLEMENT (create_channel);
      IMPLEMENT (ensure_channel);
    #undef IMPLEMENT
    }

### tp_svc_channel_dispatcher_return_from_create_channel ()

    void                tp_svc_channel_dispatcher_return_from_create_channel
                                                            (DBusGMethodInvocation *context,
                                                             const gchar *out_Request);

Return successfully by calling `dbus_g_method_return()`. This inline function exists only to provide type-safety.
