Gets the clock vector that is associated with the specified change unit ID.
HRESULT FindClockVectorForChangeUnit( const BYTE *pbItemId, const BYTE *pbChangeUnitId, REFIID riid, IUnknown **ppUnk);
[in] The ID of the item that contains the change unit that is associated with the clock vector to retrieve.
[in] The ID of the change unit that is associated with the clock vector to retrieve.
[in] The IID of the object to retrieve. Must be IID_IEnumClockVector.
[out, riid_is(riid)] Returns an object that implements riid and that can enumerate the list of IClockVector objects that is associated with pbChangeUnitId.
