CeFindFirstDatabaseEx (CEDB) (Windows CE 5.0)
This function opens an enumeration context for all databases in a database volume.
This function does not work with EDB databases. For more information on EDB, see EDB Functions.
A RAPI version of this function exists named CeFindFirstDatabaseEx (RAPI).
HANDLE CeFindFirstDatabaseEx( PCEGUID pceguid,DWORD dwDbaseType);
Parameters
- pceguid
[in] Pointer to the CEGUID that contains the globally unique identifier of a mounted database volume. If pceguid points to the system GUID value, the object store is used as the database volume. If pceguid is NULL or set to an invalid GUID, then all mounted database volumes are searched. - dwDbaseType
[in] Type identifier of the databases to enumerate. If this parameter is zero, all databases are enumerated in the volume. For Windows CE–based devices, a volume is the object store or a mounted database volume.
Return Values
A handle to an enumeration context indicates success. INVALID_HANDLE_VALUE indicates failure. To get extended error information, call GetLastError. GetLastError may return ERROR_OUTOFMEMORY if no memory is available to allocate an enumeration context handle.
Remarks
This function only returns the handle to a enumeration context. To begin enumerating databases, an application must call the CeFindNextDatabaseEx function. When an application is done with the handle to the enumeration context, an application uses CloseHandle to release the resources associated with the enumeration context. To find the databases of the desired type, specify the enumeration context handle in multiple calls to the CeFindNextDatabaseEx (CEDB) function.
You can create a system GUID using the CREATE_SYSTEMGUID macro and you can create an invalid GUID using the CREATE_INVALIDGUID macro.
Requirements
OS Versions: Windows CE 2.10 and later.
Header: Windbase.h.
Link Library: Coredll.lib.
