Gio.SocketService::incoming

connect('incoming', function (socketService, connection: Gio.SocketConnection, source_object: GObject.Object, ): Boolean);
  

The ::incoming signal is emitted when a new incoming connection to @service needs to be handled. The handler must initiate the handling of connection, but may not block; in essence, asynchronous operations must be used.

connection will be unreffed once the signal handler returns, so you need to ref it yourself if you are planning to use it.
