I'm using boost::asio, version boost is 1.71. Initially i have ip::tcp::socket object, name it "socket". I need to get the io_context, used by this socket. In early boost versions (1.62, for example) it was simple. There was asio::basic_socket::get_io_service() method. But how can i do it in boost 1.71? This necessity appeared since i have a project that intensively uses boost1.62 and "asio::basic_socket::get_io_service()" used ubiquitously. I have tried: // socket asio::executor e = socket.get_executor();...
