IEmptyVolumeCache interface (emptyvc.h)

  • Article

Used by the disk cleanup manager to communicate with a disk cleanup handler. Exposes methods that enable the manager to request information from a handler, and notify it of events such as the start of a scan or purge.

Inheritance

The IEmptyVolumeCache interface inherits from the IUnknown interface. IEmptyVolumeCache also has these types of members:
