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.

HTH / Johan Thanks, I'll try that.
