Oh.  That makes sense.  I think that's how the native socket call is.  Thanks.

I know how to do this with Windows sockets, but how do I bind a UDP listen

hard code it, I can only run a single client on a PC.  I want to bind to
the first available one so I can run as many clients on the same PC as I
want.

AFAIK, just bind to port 0 and you will get assigned a random port.

Cheers,
