This has almost the same semantics as WSAECONNRESET and for all practical purposes is handled the same. The main difference is about *who* reset the connection: the peer or something in the network. For UDP sockets this happens when receiving packets and previously sent packets returned an ICMP "Time(-to-live) expired" message. This is similar to WSAECONNRESET, which on UDP sockets happens when receiving packets and previously sent packets returned an ICMP "Port Unreachable" message.
