请说明如何制作事件级套接字程序 [英] Please tell how to make event level socket program

问题描述

我正在尝试制作一个套接字程序，该程序可以连接到服务器并发送消息，但我无法执行的操作是:-
创建一个事件，如果在我通过该套接字连接到套接字的套接字上写了一些东西，并且必须在该事件上调用recv()时，将设置该事件.
如果我没有收到服务器的任何响应，则应在5秒钟后再次拨打send呼叫.
怎么做.
请建议

I was trying to make a socket program,in which i was able to connect to server and send message but the part that i would was not able to do is:-
Make an event which will be set if something is written on the socket through which i have connected to the socket and when the event i have to make the recv() call.
And if i didn''t get any response from the server i should make the send call again after 5 second.
How can it be done.
Please suggest

推荐答案

您真正需要的第一件事是此 [

The first thing you really need is this[^]

Then you can go on to read this[^] that might be able to help you.

在单独的线程上使用select()等待数据(您也可以设置超时值).
然后调用recv()读取数据.如果发生超时，请(重新)将数据发送到您的服务器.

Use select() on a separate thread to wait for data (you can also set a timeout value).
Then call recv() to read the data. If timeout occurs, (re)send data to your server.
