WMDRM_IMPORT_CONTENT_KEY structure

[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 It has been superseded by Source Reader and Sink Writer.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 WMDRM_IMPORT_CONTENT_KEY structure stores the content key used in importing protected content.

Syntax

typedef struct WMDRM_IMPORT_CONTENT_KEY {
  DWORD dwVersion;
  DWORD cbStructSize;
  DWORD dwIVKeyType;
  DWORD cbIVKey;
  DWORD dwContentKeyType;
  DWORD cbContentKey;
  BYTE  rgbKeyData[1];
} ;

Members
