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.<163>
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.
