For non-blocking calls you need to use CAsyncSocket instead. Blocking is explained here:
http://msdn.microsoft.com/en-us/library/3tbz7kf5%28v=vs.100%29.aspx[^].

I would advise to use CSocket and blocking calls with threads. Do all networking in separate threads. I think asynchronous APIs were offered when threads were not a commonplace and presently does not make a lot of sense. Threaded solutions are more straightforward, and the role of asynchronous callbacks, etc are played by thread communication primitives which are more explicit and give you more control.
