Re: [Boost-users] [Asio] Any port with an endpoint

In windows there is the capability to create a socket with an address but leave the port number up to windows to select. Is this possible with the asio endpoint or will I always need to define "some" port number?

Something like this used to work (old version of asio): ---- (some using declarations omitted) asio::io_service ios; tcp::socket s(ios); tcp::socket::endpoint_type ep(tcp::v4(), 0); // NOTE: Usage of "0" s.open(tcp::v4()); s.set_option(tcp::socket::reuse_address(true)); s.bind(ep); --- s.local_endpoint().port() now holds actual port number bound to.
