[COLOR="RoyalBlue"]GetQueuedCompletionStatus
The GetQueuedCompletionStatus function attempts to dequeue an I/O completion packet from a specified I/O completion port. If there is no completion packet queued, the function waits for a pending I/O operation associated with the completion port to complete.
BOOL GetQueuedCompletionStatus(
HANDLE CompletionPort, // handle to completion port
LPDWORD lpNumberOfBytes, // bytes transferred
PULONG_PTR lpCompletionKey, // file completion key
LPOVERLAPPED *lpOverlapped, // buffer
DWORD dwMilliseconds // optional timeout value
);[/COLOR]
