IWMDRMLicenseBackupRestoreStatus interface
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IWMDRMLicenseBackupRestoreStatus interface provides a method to retrieve detailed status information about a license backup or restore operation.
This interface is delivered with progress events generated during license backup and restore operations. Several MEWMDRMLicenseBackupProgress events are generated during license backup, each of which has an accompanying instance of this interface. The same is true of MEWMDRMLicenseRestoreProgress events, which are generated during license restoration.
To retrieve a pointer to an instance of the IWMDRMLicenseBackupRestoreStatus interface, you must first call the IMFMediaEvent::GetValue method of the progress event. The value you retrieve from the event is a pointer to the IUnknown interface of the object that implements the IWMDRMLicenseBackupRestoreStatus interface.
