Comments

This function is basically the same as IltmmCapture::GetSubObject, but retrieves the objects IDispatch interface instead of IUnknown.

This function was added for languages like FoxPro that will not query for the dispatch interface itself.

If the function succeeds, the caller should release the retrieved interface pointer by calling the interfaces Release method.
