Remarks
The notification structure returned by the system must be freed after the notification has been processed. Call CeFreeNotificationto free the notification structure.
Note Earlier versions of Windows CE assigned OIDs to objects in other file systems, such as the FAT file system. These OIDs were guaranteed to be unique within a volume, but not across multiple volumes. Effective with version 3.0, only objects in the object store have valid, unique OIDs and the object store is the only volume that can return an object identifier.
