CancelIo() is supposed to cancel all pending I/O operations associated with the calling thread. In my experience, CancelIo() sometimes cancels future I/O operations as well. Given:.......

The key point here is that there is no way to detect when CancelIo() has finished executing. How can I ensure that CancelIo() is done executing and it is safe to issue further read requests?.......

Upon further investigation it turns out that the code was invoking CancelIo() followed by ReadFile() with a timeout INFINITE. The completion port was never getting notified of the read because the remote end was never sending anything. In other words, CancelIo() did not cancel subsequent operations........

It turns out that device drivers may choose to treat an asynchronous operation in a synchronous manner if the data being read is already cached by the device driver. Upon further investigation, I discovered that when CancelIo() was being invoked before ReadFile() it would sometimes cause the latter to return synchronously. I have no idea why the completion port was never getting notified of ReadFile() after a CancelIo() but I can no longer reproduce this problem........
