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

The server MUST then perform the following in sequence. Errors generated in this sequence of stepsare returned in the pHrResult parameter to the IVdsAsync::Wait or IVdsAsyncQueryStatus methods.•Format the volume following the parameters specified to the method.•For each callback object registered in the list of callback objects, call the callback object'sIVdsAdviseSink::OnNotify() method with a VDS_NOTIFICATION structure with the followingattributes:•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 system 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.3.4.5.2.32.3 IVdsVolumeMF::AddAccessPath (Opnum 5)The AddAccessPath method adds an access path to the current volume.HRESULT AddAccessPath([in, max_is(MAX_PATH - 1), string]WCHAR* pwszPath);pwszPath: A null-terminated Unicode string that indicates the access path. A trailing backslashMUST be included if the access path is a drive letter (for example, "F:\").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 pwszPath is not NULL.The server MUST then perform the following in sequence:•Add the access path to the volume.•If the server determines that a mounted folder path name was added to the volume, for eachcallback object that is registered in the list of callback objects, the server MUST call the callback[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011250 / 360
