[python-win32] Asynchronous UDP socket programming

[Jens B. Jorgensen]

The "Windows" way to do asynchronous sockets is to either call 
WSAAsyncSelect to tell winsock to post a windows message to a windows 
message queue (you pass an HWND) or you can call WSAEventSelect to have 
an Event object signalled. It looks liek WSAAsyncSelect is not available 
in the win32 extensions but WSAEventSelect is.

However, select should work fine for you. I say that because I have 
written a fair amount of socket code (both UDP and TCP) that uses select 
and runs "asynchronously" (in the sense that the code would use select() 
rather than just calling recv() and waiting indeterminately). It worked 
fine for me. What's your problem exactly? Could you be a little more 
specific than just saying you failed? Could you perhaps send us code 
examples? Help us help you!
