## Description

A "tube" is a mechanism for arbitrary data transfer. This section documents the auto-generated C wrappers for the Tube channel interface, StreamTube channel type and DBusTube channel type.

## Details

### TpSvcChannelInterfaceTube

    typedef struct _TpSvcChannelInterfaceTube TpSvcChannelInterfaceTube;

Dummy typedef representing any implementation of this interface.

### TpSvcChannelInterfaceTubeClass

    typedef struct _TpSvcChannelInterfaceTubeClass TpSvcChannelInterfaceTubeClass;

The class of TpSvcChannelInterfaceTube. This interface has no D-Bus methods, so an implementation can typically pass `NULL` to `G_IMPLEMENT_INTERFACE()` as the interface initialization function.

### tp_svc_channel_interface_tube_emit_tube_channel_state_changed ()

    void                tp_svc_channel_interface_tube_emit_tube_channel_state_changed
                                                            (gpointer instance,
                                                             guint arg_State);

Type-safe wrapper around g_signal_emit to emit the TubeChannelStateChanged signal on interface org.freedesktop.Telepathy.Channel.Interface.Tube.

`instance` : | The object implementing this interface
`arg_State` : | guint (FIXME, generate documentation)

### TpSvcChannelTypeStreamTube

    typedef struct _TpSvcChannelTypeStreamTube TpSvcChannelTypeStreamTube;

Dummy typedef representing any implementation of this interface.

### TpSvcChannelTypeStreamTubeClass

    typedef struct _TpSvcChannelTypeStreamTubeClass TpSvcChannelTypeStreamTubeClass;

The class of TpSvcChannelTypeStreamTube.

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_type_stream_tube (gpointer klass,
        gpointer unused G_GNUC_UNUSED)
    {
    #define IMPLEMENT(x) tp_svc_channel_type_stream_tube_implement_##x (\
      klass, my_object_##x)
      IMPLEMENT (offer);
      IMPLEMENT (accept);
    #undef IMPLEMENT
    }

                                                             GHashTable *in_parameters,
                                                             DBusGMethodInvocation *context);
