The object identifier of the next database in the enumeration indicates success. Zero indicates that there are no more databases left to enumerate, or that an error occurred. To get extended error information, call IRAPISession::CeGetLastErrorand IRAPISession::CeRapiGetError. Possible values for IRAPISession::CeGetLastErrorinclude the following:

ERROR_NO_MORE_ITEMS

The object store contains no more databases to enumerate.

ERROR_INVALID_PARAMETER

The hEnumparameter specified an invalid handle.

To loop over all databases in the enumeration, call IRAPISession::CeFindNextDatabaseuntil 0 is returned. If a database is deleted during enumeration, IRAPISession::CeFindNextDatabasefails and returns ERROR_KEY_DELETED. If this error occurs, you must restart the enumeration with a call to IRAPISession::CeFindFirstDatabase. When enumeration is complete, the hEnumhandle must be closed by calling the IRAPISession::CeCloseHandlefunction.

Note:

Earlier versions of Windows Embedded CE assigned object identifiers to objects in other file systems, such as the file allocation table (FAT) file system. These object identifiers 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 object identifiers and the object store is the only volume that can return an object identifier.
