CeFindFirstDatabaseEx (RAPI) (Windows CE 5.0)
This function opens an enumeration context for all databases in a database volume.
CeFindFirstDatabaseEx is a remote application interface (RAPI), which enables an application running on a desktop computer to make function calls on a Windows CE–based device.
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] Specifies the type identifier of the databases to enumerate. If this parameter is 0, 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 CeGetLastError. CeGetLastError may return ERROR_OUTOFMEMORY if no memory is available to allocate a database handle.
To find all the databases of the desired type, specify the enumeration context handle in multiple calls to the CeFindNextDatabaseEx function.
Remarks
This function only returns the handle to an enumeration context. To begin enumerating databases, an application must call the CeFindNextDatabaseEx (RAPI) function. When an application is done with the handle to the enumeration context, an application uses CeCloseHandle to release the resources associated with the enumeration context.
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: Rapi.h.
Link Library: Rapi.lib.
