Members

`HWProtectionFunctionID`

Specifies the function ID of the DRM command. The values and meanings of the function ID are defined by each individual DRM component.

`pInputData`

Pointer to a buffer containing a D3DWDDM2_0DDI_KEY_EXCHANGE_HW_PROTECTION_INPUT_DATA structure, reserved memory for IHV use, and the input data for the DRM command.

`pOutputData`

Pointer to a buffer containing a D3DWDDM2_0DDI_KEY_EXCHANGE_HW_PROTECTION_OUTPUT_DATA structure, reserved memory for IHV use, and the output data for the DRM command.

`Status`

Returns the result of the hardware DRM command.

Remarks

A pointer to this structure is passed in as the pData parameter of NegotiateCryptoSessionKeyExchange function when the CryptoSession object is creating using the D3DWDDM2_0DDI_KEY_EXCHANGE_HW_PROTECTION key exchange type.
