BOOL AsyncSelect( long lEvent = FD_READ | FD_WRITE | FD_OOB | FD_ACCEPT | FD_CONNECT | FD_CLOSE ); 参数lEvent 指定网络活动的组合应用程序感兴趣的位掩码。 FD_READ 希望接收准备的通知阅读。 数据,则可读取时,FD_WRITE 希望接收通知。 FD_OOB 希望接收带外数据到达的通知。 FD_ACCEPT 希望接收传...
// Incorrect example.rc = WSPAsyncSelect(s, hWnd, wMsg1, FD_READ, &error); rc = WSPAsyncSelect(s, hWnd, wMsg2, FD_WRITE, &error); 若要取消所有通知 (,表示服務提供者不應該傳送與套接字) 上網路事件相關的進一步訊息,請將lEvent設定為零。

1. FD_ACCEPT:当一个连接请求被接受时触发。 2. FD_READ:当套接字有数据可读时触发。 3. FD_WRITE:当套接字可以写入数据时触发。 4. FD_CLOSE:当套接字关闭时触发。 通过asyncselect方法将套接字与这些事件绑定后,程序员可以在相应的事件处理函数里面实现相应的逻辑。 三、asyncselect的使用方法 下面我们将...

叫用套接字的 LPWSPAsyncSelect 會取消相同套接字的任何先前 LPWSPAsyncSelect 或LPWSPEventSelect。 例如,若要同時接收讀取和寫入的通知,Windows Sockets SPI 用戶端必須呼叫 LPWSPAsyncSelect 與FD_READ 和 FD_WRITE,如下所示。C++ 複製 rc = WSPAsyncSelect(s, hWnd, wMsg, FD_READ | FD_WRITE, &error)...
