How do I get the UDP port from network_create_socket()?

[GhostlyImprints]

Is there a way to get the port that was used when calling this function:
network_create_socket(network_socket_udp);

Only way I've found is to fire a datagram to a server and get the port that way, but is it possible to do it locally?

Can I retrieve the port I just opened in GameMaker itself?

Something like this:

socket = network_create_socket(network_socket_udp);
port = network_get_socket_port(socket);

At the very least, you can define the port for the socket you created with the network_create_socket_ext function.

And basically, if that function returns < 0 then attempt a new port? I'm assuming it would usually return < 0 if the port isn't available?
