IWMDRMDeviceApp interface
[The Windows Media DRM feature is deprecated and should not be used. Use Microsoft PlayReady instead.]
The IWMDRMDeviceApp interface enables an application to meter, synchronize licenses, and update a device's DRM components. This interface will only work with devices that support Windows Media DRM 10 for Portable Devices.
To get this interface, call CoCreateInstance, passing in CLSID_WMDRMDeviceApp.
Note
This interface is defined in the header file built from WMDRMDeviceApp.idl. This header #includes "wmdm.h". You might need to change this file name to match the header built from WMDM.idl.
