I learned IOCP by this sample:

http://www.codeproject.com/internet/winsockiocp.asp

Using IOCP means that you associate some I/O operations (file, socket...) with completion port. Now any I/O operation (ReadFile, send, recv...) returns immidiately, and program waits for it's actual completion on completion port. All IOCP sample are complicated, but you need to spend your time and understand one of them.
