在服务器中使用WSAAsyncSelect（）函数来处理多个客户端

问题描述

我的服务器端有一个异步套接字。只要在套接字上有要读取或写入的内容，就会生成窗口的消息。现在，服务器上只有一个异步套接字可以处理多个客户端的请求。但如果客户数超过，我不确定这是否有效。如果我需要处理40个客户端，是否需要在服务器端创建40个异步套接字来同时处理40个客户端中的每个客户端的请求？我不确定如何将此单服务器单客户端应用程序扩展到多个客户端应用程序。任何人都可以给我一些指导如何前进？下面是我在服务器端使用单个异步套接字完成的代码：

I have a single asynchronous socket at my server side. whenever there is something to be read or written on the socket, a window''s message is generated. Right now there is only one single asynchronous socket on the server that handles requests of more than one client I guess. But I am not sure will this work if number of clients exceed. If I need to handle 40 clients, do I need to create 40 asynchronous sockets at server side to handle request of each of the 40 clients simultaneoulsy? I am not sure how to extend this single server single client application to multiple clients application. Can anybody give me some guidlines how to move forward? below is the code I done at server side with a single asynchronous socket:

WSAAsyncSelect (socketIdentifier, hwnd, MY_MESSAGE_NOTIFICATION, FD_READ | FD_CONNECT | FD_CLOSE | FD_ACCEPT); //Making the socket Asynchronous
   while(GetMessage(&Msg, NULL, 0, 0) > 0) //Waiting for windows messages
      {
         TranslateMessage(&Msg);
         DispatchMessage(&Msg);
      }
   return Msg.wParam;


    LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
    {
       switch(msg)
          {
           case MY_MESSAGE_NOTIFICATION: //Window message generated by asynchronous socket.
            {
             switch (lParam) //If so, which one is it?
                {
                case FD_ACCEPT:
                    //Connection request was made
                    break;

                case FD_CONNECT:
                    //Connection was made successfully
                    break;

                case FD_READ:
                   receiveAtSocket();
                break;

                case FD_CLOSE:
                    //Lost the connection
                 break;
                }
            }
            break;
        }
    }
