IMFSourceResolver::CancelObjectCreation method (mfidl.h)
Cancels an asynchronous request to create an object.
Syntax
HRESULT CancelObjectCreation(
[in] IUnknown *pIUnknownCancelCookie
);
Parameters
[in] pIUnknownCancelCookie
Pointer to the IUnknown interface that was returned in the ppIUnknownCancelCookie parameter of the IMFSourceResolver::BeginCreateObjectFromByteStream or IMFSourceResolver::BeginCreateObjectFromURL method.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
You can use this method to cancel a previous call to BeginCreateObjectFromByteStream or BeginCreateObjectFromURL. Because these methods are asynchronous, however, they might be completed before the operation can be canceled. Therefore, your callback might still be invoked after you call this method.
Note This method cannot be called remotely.
