Shutting down the server from a message

[EdwardClements]

I have seen a few discussions on shutting down a server, but I am new to uWebSockets and I cannot find out how to call us_listen_socket_close() -- my simple code for a message (taken from the EchoServer.cpp example is

			.message = [](auto* ws, std::string_view message, uWS::OpCode opCode) {
				std::cout << "Message: " << message << std::endl;
				std::string msg(message);
				msg += " (Echo)";
				ws->send(msg, opCode, true);
				if (message == "stop")
				{	Loop *loopToShutdown = Loop::get();
					loopToShutdown->defer([]() {
					  us_listen_socket_close(0, **????**);
					});
				}
			},

Can someone help me with the us_listen_socket_close() call?

You get the us_listen_socket_t in the listen callback. It's the one often called "token" which is misleading

Thanks a lot, it works like a charm (I was a bit confused with all the auto* types).

For those who land in a similar situation like myself here is a short summary of the changes:

us_listen_socket_t *g_pSocket = NULL; // before main()

			.message = [](auto* ws, std::string_view message, uWS::OpCode opCode) {
				std::cout << "Message: " << message << std::endl;
				std::string msg(message);
				msg += " (Echo)";
				ws->send(msg, opCode, true);
				if (message == "stop")
				{	Loop *loopToShutdown = Loop::get();
					loopToShutdown->defer([]() {
					  us_listen_socket_close(0, g_pSocket);
					});
				}
			},

...

			}).listen(nPort, [](us_listen_socket_t * listen_socket) {
				if (listen_socket) {
					g_pSocket = listen_socket;
					std::cout << "Listening on port " << nPort << std::endl;
				}
