  • 發行項

InputBuffer is a FILE_FS_OBJECTID_INFORMATION structure, as described in [MS-FSCC] section 2.5.6.<191>

Pseudocode for the operation is as follows:

  • If InputBufferSize is less than sizeof(FILE_FS_OBJECTID_INFORMATION), the operation MUST be failed with STATUS_INVALID_INFO_CLASS.

  • Support for ObjectIDs is optional. If the object store does not implement this functionality, the operation MUST be failed with STATUS_INVALID_PARAMETER.<192>

  • If Open.File.Volume.IsObjectIDsSupported is FALSE, the operation MUST be failed with STATUS_VOLUME_NOT_UPGRADED.

  • Open.File.Volume MUST be updated as follows:

    • Open.File.Volume.VolumeId set to InputBuffer.ObjectId.

    • Open.File.Volume.ExtendedInfo set to InputBuffer.ExtendedInfo.

  • Upon successful completion of the operation, the object store MUST return:

    • Status set to STATUS_SUCCESS.
