I wasn’t afraid to ask. I asked several times. I just never got an answer.
Nice trolling with the UDP joke :)
In writing this blog post I’ve spent like three days trying to understand what IP_RECVERR does. It’s amazing how little docs there are.

The best thing one can do to learn this build a simple P2P file transfer system. That us how I learned all of this, a lot of time you take things for granted and don’t pay attention to details despite being told to you. Implementing P2P really helps asking these questions.
Thanks for posting this!
The wildcard issue was new to me and I have a number of server apps affected by it.
