PostQueuedCompletionStatus
The PostQueuedCompletionStatus function lets you post an I/O completion packet to an I/O completion port.
The I/O completion packet will satisfy an outstanding call to the GetQueuedCompletionStatus function. The GetQueuedCompletionStatus function returns with the three values passed as the second, third, and fourth
parameters of the call to PostQueuedCompletionStatus.
BOOL PostQueuedCompletionStatus(
HANDLE CompletionPort,
| // handle to an I/O completion port
| DWORD dwNumberOfBytesTransferred,
| // value to return via
// GetQueuedCompletionStatus'
// lpNumberOfBytesTranferred
| DWORD dwCompletionKey,
| // value to return via
// GetQueuedCompletionStatus'
// lpCompletionKey
| LPOVERLAPPED lpOverlapped
| // value to return via
// GetQueuedCompletionStatus' lpOverlapped
| );
|
