IHostIoCompletionManager Interface
Provides methods that allow the common language runtime (CLR) to interact with I/O completion ports provided by the host.
interface IHostIoCompletionManager : IUnknown {
HRESULT Bind (
[in] HANDLE hPort,
[in] HANDLE hHandle
);
HRESULT CloseIoCompletionPort (
[in] HANDLE hPort
);
HRESULT CreateIoCompletionPort (
[out] HANDLE *phPort
);
HRESULT GetAvailableThreads (
[out] DWORD *pdwAvailableIOCompletionThreads
);
HRESULT GetHostOverlappedSize (
[out] DWORD *pcbSize
);
HRESULT GetMaxThreads (
[out] DWORD *pdwMaxIOCompletionThreads
);
HRESULT GetMinThreads (
[out] DWORD *dwMinIOCompletionThreads
);
HRESULT InitializeHostOverlapped (
[in] void* pvOverlapped
);
HRESULT SetCLRIoCompletionManager (
[in] ICLRIoCompletionManager* pManager
);
HRESULT SetMaxThreads (
[in] DWORD dwMaxIOCompletionThreads
);

};
Methods
| Method | Description |
|---|---|
Binds a handle to an I/O completion port. |
|
Closes a port that was created through an earlier call to CreateIoCompletionPort. |
|
Requests that the host create a new I/O completion port. |
|
Gets the number of I/O completion threads that are not currently processing requests. |
|
Gets the size of any custom data the host intends to append to I/O requests. |
|
Gets the maximum number of threads that the host can allot to service I/O requests. |
|
Gets the minimum number of threads that the host provides to service I/O requests. |
|
Provides the host with an opportunity to initialize any custom data about an I/O request. |
|
Provides the host with an interface pointer to an ICLRIoCompletionManager Interface instance implemented by the CLR. |
|
Sets the maximum number of threads that the host allots to service I/O requests. |
|
Sets the minimum number of threads that the host should allot to I/O completion. |
Remarks
IHostIoCompletionManager corresponds to the ICLRIoCompletionManager Interface interface implemented by the CLR. The CLR calls the methods of IHostIoCompletionManager to bind handles to the ports that the host provides, and the host calls the methods of ICLRIoCompletionManager to report the completion of I/O requests.
