Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3d11ddi_clearunorderedaccessviewfloat)

PFND3D11DDI_CLEARUNORDEREDACCESSVIEWFLOAT callback function

Description

The ClearUnorderedAccessViewFLOAT function clears the specified unordered-access view by setting it to a constant value.

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

unnamedParam2

hUnorderedAccessView [in]

A handle to the unordered-access view to clear.

FLOAT [in]

[4]

A four-element array of single-precision float vectors that the driver uses to clear an unordered-access view.

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code.

The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime determines that the error is critical. Even if the device is removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interferes with the operation of ClearUnorderedAccessViewFLOAT (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
