CeOidGetInfoEx (RAPI) (Windows Embedded CE 6.0)

  • [アーティクル]

1/6/2010

This function retrieves information about an object in the object store or a mounted database volume store on a remote Windows Embedded CE–based device.

Syntax

BOOL CeOidGetInfoEx(
  PCEGUID pceguid, 
  CEOID oid,
  CEOIDINFO * poidInfo 
);

Parameters

  • pceguid
    [in] Pointer to the CEGUID that contains the globally unique identifierof a mounted database or the object store. Use the CREATE_SYSTEMGUID macro to obtain the GUID of the object store.
  • oid
    [in] Identifier of the object for which information is to be retrieved.
  • poidInfo
    [out] Pointer to a CEOIDINFO structure that contains information about the object.

Return Value

Nonzero indicates success. Zero indicates failure. To get extended error information, call CeGetLastError and CeRapiGetError. CeGetLastError may return ERROR_INVALID_HANDLE if the specified object identifier is invalid.

Remarks

The difference between CeOidGetInfo and CeOidGetInfoEx is that CeOidGetInfo retrieves information about objects only in the object store databases, while CeOidGetInfoEx retrieves information about any object in mounted database volumes in addition to the object store databases.

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.
