Windows main loop and a server loop on 2 threads

I'm trying to setup mongoos server in a Winndows app.
The server code needs to be in an infinite loop, so does the windows main loop. I put the server code and win loop on 2 threads, the problem is, the program hangs when executed.
Is there a way to make this work




Main Windows loop

Code:

---

        int mainLoop(MSG &messages) {
                while (GetMessage(&messages, NULL, 0, 0))
                {
                        TranslateMessage(&messages);
                        DispatchMessage(&messages);
                }


                return 1;
        }

---

Server loop

Code:

---

        int serverLoop() {

                struct mg_mgr mgr;
                struct mg_connection *c;
                static const char *s_http_port = "80";

                mg_mgr_init(&mgr, NULL);
                c = mg_bind(&mgr, s_http_port, ev_handler);
                mg_set_protocol_http_websocket(c);

                for (;;) {
                        mg_mgr_poll(&mgr, 1000);
                }
                mg_mgr_free(&mgr);

                return 0;
        }

---

Main

Code:

---

int WINAPI WinMain(HINSTANCE hThisInstance,HINSTANCE hPrevInstance,LPSTR lpszArgument,int nCmdShow){

 // ...
 
        thread first(mainLoop,messages); 
        thread second(serverLoop);

        first.join();             
        second.join();

Consider using PeekMessage() and in your ev_handler function communicate with the GUI thread.

I think it's best to have your main message loop on the main thread, and just have a worker thread to have your serverLoop.

You should use PeekMessage().
