How to make boost::asio::ip::tcp::acceptor block forever?

Question

How would someone do that? It just blocks until the first connection attempt.

Answer 1

I don't think you can, accept will block until the first connection arrives and async_accept won't block at all (and will only handle the first connection as well). However, why do you want this? You can always initiate another accept once the previous one returned. It's not like you'd miss anything since accept only removes theses connections from the listening sockets queue .

Answer 2

boost::asio::ip::tcp::acceptor::accept 方法已经阻塞，直到尝试连接为止。
