This gio.socket_control_message.SocketControlMessage contains a gio.unix_fdlist.UnixFDList. It may be sent using gio.socket.Socket.sendMessage and received using gio.socket.Socket.receiveMessage over UNIX sockets (ie: sockets in the gio.types.SocketFamily.Unix family). The file descriptors are copied between processes by the kernel.
For an easier way to send and receive file descriptors over stream-oriented UNIX sockets, see gio.unix_connection.UnixConnection.sendFd and gio.unix_connection.UnixConnection.receiveFd.
Note that <gio/gunixfdmessage.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file or the GioUnix-2.0 GIR namespace when using it.
