HANDLE CreateIoCompletionPort(

IN HANDLE FileHandle,

IN HANDLE ExistingCompletionPort,

IN ULONG_PTR CompletionKey,

IN DWORD NumberOfConcurrentThreads

);

怎么没有人回答啊..~~~

哦...

HANDLE CreateNewCompletionPort(DWORD dwNumberOfThreads)
{
return CreateIoCompletionPort(INVALID_HANDLE_VALUE,NULL,NULL,dwNumberOfThreads);
};

这个怎么用呢?
bool AssicoateDeviceWithCompletionPort(HANDLE hCompPort,HANDLE hDevice,DWORD dwCompKey)
{
HANDLE h=CreateIoCompletionPort(hDevice,hCompPort,dwCompKey,0);
return h==hCompPort;
};

BOOL GetQueuedCompletionStatus(
IN HANDLE CompletionPort,
OUT LPDWORD lpNumberOfBytesTransferred,
OUT PULONG_PTR lpCompletionKey,
OUT LPOVERLAPPED *lpOverlapped,
IN DWORD dwMilliseconds
);
