如何在C ++中处理异步套接字接收？

Question

I'm currently using a thread to handle Connect and Send calls asynchronously. This is all working fine, but now I want to make receiving asynchronous too. How should I receive data without pausing the whole queue while waiting for data? The only solution I can think of right now is a second thread.

Answer 1

Look into non-blocking sockets and polling APIs like select(2) / poll(2) / epoll(4) / kqueue(2) .

Specifically in C++, look into boost::asio .

Answer 2

Depending on what you're doing, non-blocking I/O with select may be the answer.
