I see. The question is if we're able to get around that Winsock'ism.
Perhaps Winsock2 helps a bit.
This is just brainstorming, I have no idea if that works:
When connect is called, create a duplicate of the socket first,
before actually connecting, using the WSADuplicateSocket call.
This should give you a structure describing the socket in exactly
the state before the ::connect call. Now for the cases:
- Normal connect, success, erase the duplicate.
- Normal connect, failure, ditto.
- Interrupt, close original socket and recreate it from the duplicate
Would that work???
