Otherwise, this parameter points to an SID and the remaining OUT parameters are provided valid return values. OwnerDefaulted - This value is returned only if the value returned for the Owner parameter is not null. In this case, the OwnerDefaulted parameter receives the value of the security descriptor's OwnerDefaulted control flag. Return Value: STATUS_SUCCESS - Indicates the call completed successfully. STATUS_UNKNOWN_REVISION - Indicates the revision of the security descriptor is not known to the routine. It may be a newer revision than the routine knows about.
