IWMDRMEditor interface (wmsdkidl.h)
[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 It has been superseded by Source Reader and Sink Writer.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.]
[IWMDRMEditor is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Microsoft PlayReady. ]
The IWMDRMEditor interface is exposed on the metadata editor object. It can be obtained by calling QueryInterface from IWMMetadataEditor. The IWMDRMEditor interface enables applications to examine the DRM attributes of an ASF file, for example to query the number of times a file is allowed to be played, without having the wmstubdrm.lib static library. The IWMDRMReader interface contains a similar method, but the application must be linked to a valid wmstubdrm.lib library in order to use that interface.
