Allows the display driver to return IHV-specific information used when initializing a new hardware key.

Syntax

virtual HRESULT InitializeHardwareKey(
  [in]                                                     UINT   InputPrivateDataByteCount,
  [in, size_is(InputPrivateDataByteCount), optional] const void   *InputPrivateData,
  [out]                                                    UINT64 *OutputPrivateData
) = 0;

Parameters

InputPrivateDataByteCount [in]

The number of bytes in the buffer that InputPrivateData specifies.

InputPrivateData [in, optional]

The contents of this parameter are defined by the implementation of the protection system that runs in the security processor. The contents may contain data about license or stream properties.

OutputPrivateData [out]

The return data is also defined by the implementation of the protection system implementation that runs in the security processor. The contents may contain data associated with the underlying hardware key.
