Is it possible to detach a native socket from Boost.ASIO’s socket class? If so, how can it be done? I can’t seem to find anything obvious in the documentation.
As a quick overview of what I’m trying to accomplish: I have a class that makes a connection and does some negotiation using Boost.ASIO, then passes back a native Windows SOCKET on success or 0 on failure.
Unless I’m mistaken, the native socket will be closed and deallocated when my boost::asio::basic_socket is destructed.
Answering my own question.
Windows has a WSADuplicateSocket function, which can be used to duplicate the native socket. The underlying socket will remain open until all descriptors for this socket are deallocated.
