PFND3DWDDM2_0DDI_GETDATAFORNEWHARDWAREKEY callback function (d3d10umddi.h)

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

Syntax

PFND3DWDDM2_0DDI_GETDATAFORNEWHARDWAREKEY Pfnd3dwddm20DdiGetdatafornewhardwarekey;

HRESULT Pfnd3dwddm20DdiGetdatafornewhardwarekey(
  D3D10DDI_HDEVICE hDevice,
  D3D11_1DDI_HCRYPTOSESSION hCryptoSession,
  UINT PrivateInputSize,
  const void *pPrivatInputData,
  UINT64 *pPrivateOutputData
)
{...}

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.

Requirements

Requirement	Value
Minimum supported client	Windows 10
