The default constructor for ipv4::tcp::endpoint initializes the port to 0. Just pass a default-constructed endpoint to your socket_acceptor's ctor or to its bind method. You can then use the get_local_endpoint method to get the value of the port that was allocated by the OS. -- Caleb Epstein caleb dot epstein at gmail dot com
