STORAGE_DEPENDENCY_INFO_TYPE_2 structure (virtdisk.h)

Contains VHD or ISO storage dependency information for type 2.

Syntax

typedef struct _STORAGE_DEPENDENCY_INFO_TYPE_2 {
  DEPENDENT_DISK_FLAG  DependencyTypeFlags;
  ULONG                ProviderSpecificFlags;
  VIRTUAL_STORAGE_TYPE VirtualStorageType;

Members

DependencyTypeFlags

A DEPENDENT_DISK_FLAG enumeration.

ProviderSpecificFlags

Flags specific to the VHD provider.

VirtualStorageType

A VIRTUAL_STORAGE_TYPE structure.

AncestorLevel

The ancestor level.

DependencyDeviceName

The device name of the dependent device. If the device is a virtual hard drive then this will be in the form \.\PhysicalDriveN. If the device is a virtual CD or DVD drive (ISO) then this will be in the form \.\CDRomN. In either case N is an integer that represents a unique identifier for the caller's host system.

HostVolumeName

The host disk volume name in the form \?\Volume{GUID}\ where GUID is the GUID that identifies the volume.

DependentVolumeName

The name of the dependent volume, if any, in the form \?\Volume{GUID}\ where GUID is the GUID that identifies the volume.

DependentVolumeRelativePath

The relative path to the dependent volume.
