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).
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 gobject.types.size_t type system before calling
gio.socket.Socket.receiveMessage to read such a message.
A gio.socket_control_message.SocketControlMessage is a special-purpose utility message that can be sent to or received from a gio.socket.Socket. 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 gio.socket.Socket.sendMessage and received with gio.socket.Socket.receiveMessage.
