PFND3D10DDI_CLEARRENDERTARGETVIEW callback function (d3d10umddi.h)
The ClearRenderTargetView function clears the specified render-target view by setting it to a constant value.
Syntax
PFND3D10DDI_CLEARRENDERTARGETVIEW Pfnd3d10ddiClearrendertargetview;
void Pfnd3d10ddiClearrendertargetview(
D3D10DDI_HDEVICE unnamedParam1,
D3D10DDI_HRENDERTARGETVIEW unnamedParam2,
FLOAT[4] unnamedParam3
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pColorRGBA [in]
A four-element array of single-precision float vectors that the driver uses to clear a render-target view. Array element 0 is red (R), 1 is green (G), 2 is blue (B), and 3 is alpha (A).
unnamedParam3
hRenderTargetView [in]
A handle to the render-target view to clear.
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 will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of ClearRenderTargetView (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
