VDS_SUB_SYSTEM_NOTIFICATION structure (vdshwprv.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Defines the details of subsystem events.

Syntax

typedef struct _VDS_SUB_SYSTEM_NOTIFICATION {
  ULONG         ulEvent;
  VDS_OBJECT_ID subSystemId;
} VDS_SUB_SYSTEM_NOTIFICATION;

Members

ulEvent

Determines the subsystem event for which an application will be notified, as one of the following values.

Value Meaning
VDS_NF_SUB_SYSTEM_ARRIVE

 A new subsystem was connected to the server or network.
VDS_NF_SUB_SYSTEM_DEPART
102
 An existing subsystem was disconnected.
VDS_NF_SUB_SYSTEM_MODIFY
151
 A member of the VDS_SUB_SYSTEM_PROP structure was changed.

subSystemId

Remarks

The VDS_NOTIFICATION structure includes this structure as a member.

An application can receive subsystem events by implementing the IVdsAdviseSink interface and passing the interface pointer as an argument to the IVdsService::Advise method.

To get the subsystem object, use the IVdsService::GetObject method. You can then use the IVdsSubSystem::GetProperties method or the IVdsSubSystem2::GetProperties2 methodto get the subsystem properties.
