Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3dwddm2_0ddi_getdatafornewhardwarekey)

PFND3DWDDM2_0DDI_GETDATAFORNEWHARDWAREKEY callback function

Description

Allows the driver to return independent hardware vendor (IHV)-specific information used when initializing the new hardware key.

Parameters

`hDevice`

A handle to the display device (graphics context). The Direct3D runtime passed the user-mode driver this handle as the hDevice member of the D3DDDIARG_CREATEDEVICE structure at device creation.

`hCryptoSession`

A handle to the cryptographic session object that was created through a call to the CreateCryptoSession function.

`PrivateInputSize`

The size of the buffer pointed to by pPrivatInputData, in bytes.

`pPrivatInputData`

A pointer to a buffer that receives private input data for the driver.

`pPrivateOutputData`

A pointer to a UINT64 value that receives private driver output data that could be used later by the secure DRM component when initializing the key.

Return value

Returns one of the following values:

Return code	Description
S_OK	Private driver data was successfully returned.
E_OUTOFMEMORY	Memory was not available to complete the operation.
