## Description

This interface (auto-generated from the Telepathy spec) makes it easier to export objects implementing the Telepathy Channel.

## Details

### TpSvcChannel

### TpSvcChannelClass

    typedef struct _TpSvcChannelClass TpSvcChannelClass;

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 (gpointer klass,
        gpointer unused G_GNUC_UNUSED)
    {
    #define IMPLEMENT(x) tp_svc_channel_implement_##x (\
