Description GSocketConnection is a GIOStream for a connected socket. They can be created either by GSocketClient when connecting to a host, or by GSocketListener when accepting a new client. The type of the GSocketConnection object returned from these calls depends on the type of the underlying socket that is in use. For instance, for a TCP/IP connection it will be a GTcpConnection. Chosing what type of object to construct is done with the socket connection factory, and it is possible for 3rd parties to register custom socket connection types for specific combination of socket family/type/protocol using g_socket_connection_factory_register_type().
