In case 3, GetLastError will not be 0, in case 4, GetLastError will be 0.
Something else that might be bitting you here; you should be setting
*lpNumberOfBytes = 0 before calling GetQueuedCompletionStatus. That
way, on exit, if you have *lpNumberOfBytes == 0, you either have a
closed remote socket (GetLastError() == 0), or some error
(GetLastError() != 0).
GetQueuedCompletionStatus doesn't randomize the lpNumberOfBytes in
case of error, it just doesn't change it from what you set it to.
