ICLRIoCompletionManager::OnComplete Method
Notifies the common language runtime (CLR) of the status of an I/O request that was made by using a call to the IHostIoCompletionManager::Bind method.
Syntax
HRESULT OnComplete (
[in] DWORD dwErrorCode,
[in] DWORD NumberOfBytesTransferred,
[in] void* pvOverlapped
);
Parameters
dwErrorCode
[in] An HRESULT value that indicates the status of the bind operation.
S_OK indicates that the operation completed successfully.
HOST_E_INTERRUPTED indicates that the call terminated before completion.
E_FAIL indicates that an unknown, unrecoverable, catastrophic failure occurred.
NumberOfBytesTransferred
[in] The number of bytes transferred during the processing of the I/O request.
pvOverlapped
[in] A pointer to the OVERLAPPED structure that was passed to the call to the IHostIoCompletionManager::Bind method.
Return Value
| HRESULT | Description |
|---|---|
| S_OK | OnComplete returned successfully. |
| HOST_E_CLRNOTAVAILABLE | The CLR has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully. |
| HOST_E_TIMEOUT | The call timed out. |
| HOST_E_NOT_OWNER | The caller does not own the lock. |
| HOST_E_ABANDONED | An event was canceled while a blocked thread or fiber was waiting on it. |
| E_FAIL | An unknown catastrophic failure occurred. After a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE. |
Remarks
If the host implements an I/O completion abstraction, the CLR makes I/O requests through the host by using methods of IHostIoCompletionManager. The host then calls the OnComplete method to notify the runtime of the outcome of such requests.
