如何使套接字访问行为“异步”而不需要消息循环?

我的程序使用 NetworkOutput

class NetworkOutput
{
public:
  /* Constructs a NetworkOutput object; this constructor should not block, but it
   * should start attempting to the given host/port in the background.
   *
   * In case the connection gets closed for some reason, the object should immediately
   * try reconnecting.
   */
  NetworkOutput( const std::string &hostName, unsigned short port );

  /* Tells whether there is a remote client connected to this NetworkOutput object.
   * Clients can use this function to determine whether they need to both serializing
   * any data at all before calling the write() function below.
   */
  bool isConnected() const;

  /* Write data to the remote client, if any. In case this object is not connected
   * yet, the function should return immediately. Otherwise it should block until
   * all data has been written.
   *
   * This function must be thread-safe.
   */
  void write( const std::vector<char> &data );
};

现在,我已经使用非阻塞套接字实现了这一点。我不在家 网络输出 构造函数,我正在创建一个TCP套接字和一个内部帮助程序窗口。然后我做一个 WSAAsyncSelect WSAConnect . 这会立即返回,一旦连接成功,我的内部助手窗口的窗口过程就会得到通知。如果连接已关闭(因为远程客户端已离开),将调用消息过程,我将尝试重新连接。

WSAAsyncSelect公司 呼叫似乎没有到达我的助手窗口。

不 远程客户端 网络输出 类在调用之前不需要对复杂对象执行任何序列化工作 write() .
