PFND3D11DDI_CLEARUNORDEREDACCESSVIEWFLOAT callback function (d3d10umddi.h)
The ClearUnorderedAccessViewFLOAT function clears the specified unordered-access view by setting it to a constant value.
Syntax
PFND3D11DDI_CLEARUNORDEREDACCESSVIEWFLOAT Pfnd3d11ddiClearunorderedaccessviewfloat;
void Pfnd3d11ddiClearunorderedaccessviewfloat(
D3D10DDI_HDEVICE unnamedParam1,
D3D11DDI_HUNORDEREDACCESSVIEW unnamedParam2,
const FLOAT[4]
)
{...}
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[4]
Return value
None
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.
