need to call ssl::stream::shutdown when closing boost asio ssl socket?
boost, boost-asio, c++, sockets, ssl
Solution
It is cleanest to make `shutdown()` calls on both the `ssl::stream` and its `lowest_layer()`. The first ends the SSL connection and the second ends the TCP connection. If you're getting an error on the SSL shutdown, it may be that the other side is not being as graceful in ending the connection.
Problem
My code is as follows: ``` declaration: boost::asio::ssl::stream<boost::asio::ip::tcp::socket> m_remote_socket; m_remote_socket.shutdown(ec); if (ec) { cdbug<<"id: "<<m_id<<", error when ssl shutdown: " <<boost::system::system_category().message(ec.value()).c_str(); } m_remote_socket.lowest_layer().shutdown(boost::asio::ip::tcp::socket::shutdown_both, ec); if (ec) { cdbug<<"id: "<<m_id<<", error when tcp shutdown: "<<boost::system::system_category().message(ec.value()).c_str(); } ``` Each time I call `m_remote_socket.shutdown`, it will get an error. Such kind of unknown error with a really big error value. But it is ok to call `m_remote_socket.lowest_layer().shutdown()` directly without calling `m_remote_socket.shutdown`. Could anybody tell me how to close a ssl streaming socket?
