Basically the beginning would change to with the interface proposed by the
socket library proposal in the sandbox by Hugo and me.

       address_info_list list("www.google.com", "http");
       address_info_list::iterator ibegin=list.begin(), iend=list.end();

        std::cout << std::distance(ibegin,iend) << " addresses found\n";

        if (ibegin == iend)
        {
            std::cout << "No address found" << std::endl;
            return -1;
        }

        connector<> connector;
        connector<>::data_connection_t connection;

        connector.connect(connection, ibegin->protocol(),
ibegin->address());
        basic_socket_stream<char> sock(connection);

        ... the rest unchanged...

The design is based around the overall requirements in

originally written by Beman Dawes. The design is layered so you it can
enable complex uses for both servers and clients as well as simple uses as
the one you sketch.
