33  * A #GSocketControlMessage is a special-purpose utility message that
34  * can be sent to or received from a #GSocket. These types of
35  * messages are often called "ancillary data".
36  * 
37  * The message can represent some sort of special instruction to or
38  * information from the socket or can represent a special kind of
39  * transfer to the peer (for example, sending a file descriptor over
40  * a UNIX socket).
41  * 
42  * These messages are sent with g_socket_send_message() and received
43  * with g_socket_receive_message().
44  * 
45  * To extend the set of control message that can be sent, subclass this
46  * class and override the get_size, get_level, get_type and serialize
47  * methods.
48  * 
49  * To extend the set of control messages that can be received, subclass
50  * this class and implement the deserialize method. Also, make sure your
51  * class is registered with the GType typesystem before calling
52  * g_socket_receive_message() to read such a message.
