The Clone method makes a copy of the enumerator with the same enumeration state.
HRESULT Clone( IEnumPins **ppEnum );
[out] Address of a variable that receives a pointer to the IEnumPins interface of the new enumerator.
Returns one of the following HRESULT
|E_POINTER||NULL pointer argument.|
|VFW_E_ENUM_OUT_OF_SYNC||The filter's state has changed and is now inconsistent with the enumerator.|
If the number of pins changes, the enumerator is no longer consistent with the filter, and the method returns VFW_E_ENUM_OUT_OF_SYNC. Discard any data obtained from previous calls to the enumerator, because it might be invalid. Update the enumerator by calling the IEnumPins::Reset method. You can then call the Clone method safely.
