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

eginning of the disk that ullOffset specifies. The server MUST then return an HRESULT indicatingfailure or success. For more information on the VDS_FILE_SYSTEM_PROP structure, see section2.2.1.3.17.3.4.5.2.27.2 IVdsDiskPartitionMF::GetPartitionFileSystemTypeName (Opnum 4)The GetPartitionFileSystemTypeName method retrieves the name of the file system on a diskpartition at a specified byte offset. This method is only supported on OEM, ESP, recovery, andunknown partitions.HRESULT GetPartitionFileSystemTypeName([in] ULONGLONG ullOffset,[out, string] WCHAR** ppwszFileSystemTypeName);ullOffset: The byte offset of the partition from the beginning of the disk. This MUST be the offsetat the start of a partition.ppwszFileSystemTypeName: A pointer that, if the operation is successfully completed,receives a null-terminated Unicode string with the file system name.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.Note This method is not valid on CD/DVD or super floppy devices. These devices do notsupport partition tables.When the server receives this message, it MUST validate the following parameter:•Verify that ppwszFileSystemTypeName is not NULL.•Verify that the partition at offset ullOffset is an OEM, ESP, recovery, or unknown partition.The server MUST point ppwszFileSystemTypeName to a string containing the file system nameon the partition at the byte offset from the beginning of the disk that ullOffset specifies and thenreturn an HRESULT indicating failure or success.3.4.5.2.27.3 IVdsDiskPartitionMF::QueryPartitionFileSystemFormatSupport(Opnum 5)The QueryPartitionFileSystemFormatSupport method retrieves the properties of the filesystems that support formatting a disk partition at a specified byte offset. This method is onlysupported on OEM, ESP, recovery, and unknown partitions.Note This method is not valid on CD/DVD or super floppy devices. These devices do not supportpartition tables.HRESULT QueryPartitionFileSystemFormatSupport([in] ULONGLONG ullOffset,[out, size_is(,*plNumberOfFileSystems)]VDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP** ppFileSystemSupportProps,[out] long* plNumberOfFileSystems);[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011228 / 360
