CeFindNextDatabaseEx (RAPI)

A version of this page is also available for

Windows Embedded CE 6.0 R3


This function retrieves the next database in an enumeration context.


CEOID CeFindNextDatabaseEx( 
  HANDLE hEnum,
  PCEGUID pceguid 


  • pceguid
    [in] Pointer to the CEGUID that contains the globally unique identifier(GUID) of a mounted database.

Return Value

A valid CEOID indicates success. Zero indicates failure or a lack of additional databases. To get extended error information, call CeGetLastError and CeRapiGetError. Possible values for CeGetLastError include the following:

    There are no more databases to enumerate.
    A database was deleted during enumeration.


To find all matching databases, CeFindNextDatabaseEx is called in a loop until 0 is returned. If a database is deleted during an enumeration, CeFindNextDatabaseEx fails and returns the error ERROR_KEY_DELETED. If this error occurs, you must restart the enumeration with a call to CeFindFirstDatabaseEx. When enumeration is complete, the hEnum handle must be closed by calling the CeCloseHandle function.


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.
