/**
 * A #GSocketControlMessage is a special-purpose utility message that
 * can be sent to or received from a #GSocket. These types of
 * messages are often called "ancillary data".
 * 
 * The message can represent some sort of special instruction to or
 * information from the socket or can represent a special kind of
 * transfer to the peer (for example, sending a file descriptor over
 * a UNIX socket).
 * 
 * These messages are sent with g_socket_send_message() and received
 * with g_socket_receive_message().
 * 
 * To extend the set of control message that can be sent, subclass this
 * class and override the get_size, get_level, get_type and serialize
 * methods.
 * 
 * To extend the set of control messages that can be received, subclass
 * this class and implement the deserialize method. Also, make sure your
 * class is registered with the GType typesystem before calling
 * g_socket_receive_message() to read such a message.
