Methods

The IEmptyVolumeCacheCallBack interface has these methods.

MethodDescription

Called periodically by a disk cleanup handler to update the disk cleanup manager on the progress of a purge of deletable files.

ScanProgress

Called by a disk cleanup handler to update the disk cleanup manager on the progress of a scan for deletable files.

 

Remarks

A disk cleanup handler uses this interface to report to the disk cleanup manager on the progress either of deleting files or of scanning for deletable files. It also provides a way to query the manager, to find out if the user has canceled the operation. The handler receives a pointer to this interface when the manager calls the IEmptyVolumeCache::GetSpaceUsed or IEmptyVolumeCache::Purge methods.
