2.4.28 FileObjectIdInformation

This information class is used locally to query object ID information for the files in a directory on a volume. The query MUST fail if the file system does not support object IDs.<116>

The data returned to the caller will take one of two forms. The choice of which data structure to use, and the interpretation of the data within it, is application-specific. An application implementer chooses one of the following two data elements as the structure for its object ID information data.<117>

This operation returns a status code, as specified in [MS-ERREF] section 2.3. The status code returned directly by the function that processes this file information class MUST be STATUS_SUCCESS or one of the following.
