ClearUnorderedAccessViewFLOAT routine

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

Syntax


PFND3D11DDI_CLEARUNORDEREDACCESSVIEWFLOAT ClearUnorderedAccessViewFLOAT;

VOID APIENTRY ClearUnorderedAccessViewFLOAT(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  D3D11DDI_HUNORDEREDACCESSVIEW hUnorderedAccessView,
  _In_  const FLOAT[4] pFloats
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

hUnorderedAccessView [in]

A handle to the unordered-access view to clear.

pFloats [in]

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

Return value

None

The driver can use the pfnSetErrorCb callback function to set an error code. For more information about setting error codes, see the Remarks section.

Remarks

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.

Requirements

Version

ClearUnorderedAccessViewFLOAT is supported beginning with the Windows 7 operating system.
