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

2.2.1.3.10 VDS_ASYNC_OUTPUTThe VDS_ASYNC_OUTPUT structure provides information from a completed asynchronousoperation.typedef struct _VDS_ASYNC_OUTPUT {VDS_ASYNC_OUTPUT_TYPE type;[switch_is(type)] union {[case(VDS_ASYNCOUT_CREATEPARTITION)]struct _cp {ULONGLONG ullOffset;VDS_OBJECT_ID volumeId;} cp;[case(VDS_ASYNCOUT_CREATEVOLUME)]struct _cv {IUnknown* pVolumeUnk;} cv;[case(VDS_ASYNCOUT_BREAKVOLUMEPLEX)]struct _bvp {IUnknown* pVolumeUnk;} bvp;[case(VDS_ASYNCOUT_SHRINKVOLUME)]struct _sv {ULONGLONG ullReclaimedBytes;} sv;[case(VDS_ASYNCOUT_CREATE_VDISK)]struct _cvd {IUnknown* pVDiskUnk;} cvd;[default] ;};} VDS_ASYNC_OUTPUT;type: A value from the VDS_ASYNC_OUTPUT_TYPE enumeration that indicates the type ofoperation information.cp: The cp structure provides information about a newly created partition.ullOffset: The byte offset of the partition from the beginning of the disk.volumeId: The VDS object ID of the associated volume object, if the partition is avolume.cv: The cv structure provides information about a newly created volume.pVolumeUnk: A pointer to the IUnknown interface of the newly created volume.bvp: The bvp structure provides information about a volume after a plex is broken.pVolumeUnk: A pointer to the IUnknown interface of the volume that was broken off.sv: The sv structure provides information about a volume shrink operation.ullReclaimedBytes: The number of bytes that the volume shrink operation reclaimed.cvd: The cvd structure provides information about a newly created virtual disk.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201148 / 360
