[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

•For each callback object that is registered in the list of callback objects, call the callback object'sIVdsAdviseSink::OnNotify() method by using a VDS_NOTIFICATION structure that has thefollowing attributes:•objectType member is VDS_NTT_VOLUME.•volume member is a VDS_VOLUME_NOTIFICATION with the following attributes:•ulEvent is VDS_NF_VOLUME_MODIFY.•volumeId is the VDS_OBJECT_ID of this volume object.•If TRUE is specified for bEnableCompression and the file system being formatted supportscompression, compress the file system after formatting is complete.•Set the return code in the async object to an HRESULT indicating failure or success.•If the server tried to compress the file systems after formatting but failed, the return codeMUST be set to VDS_S_VOLUME_COMPRESS_FAILED (HRESULT of 0x00042443).•If the task completed successfully, set the percentage completed value in the async object to100.•Set the signal state in the async object to TRUE.3.4.5.2.34 IVdsVolumeMF3 Methods3.4.5.2.34.1 IVdsVolumeMF3::QueryVolumeGuidPathnames (Opnum 3)The QueryVolumeGuidPathnames method returns a volume's volume GUID path names.HRESULT QueryVolumeGuidPathnames([out, string, size_is(,*pulNumberOfPaths)]LPWSTR** pwszPathArray,[out] ULONG* pulNumberOfPaths);pwszPathArray: Returns an array of null-terminated Unicode strings; one string for eachvolume GUID path name associated with the volume.pulNumberOfPaths: Returns the number of volume GUID path names returned inpwszPathArray.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameter:•Verify that pwszPathArray is not NULL.•Verify that pulNumberOfPaths is not NULL.The server MUST then perform the following:[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011259 / 360
