PFND3D10DDI_CREATEBLENDSTATE callback function (d3d10umddi.h)
The CreateBlendState function creates a blend state.
Syntax
PFND3D10DDI_CREATEBLENDSTATE Pfnd3d10ddiCreateblendstate;
void Pfnd3d10ddiCreateblendstate(
D3D10DDI_HDEVICE unnamedParam1,
const D3D10_DDI_BLEND_DESC *unnamedParam2,
D3D10DDI_HBLENDSTATE unnamedParam3,
D3D10DDI_HRTBLENDSTATE unnamedParam4
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pBlendDesc [in]
A pointer to a D3D10_DDI_BLEND_DESC structure that describes the parameters that the user-mode display driver uses to create a blend state.
unnamedParam3
hBlendState [in]
A handle to the driver's private data for the blend state.
unnamedParam4
hRTBlendState [in]
A handle to the blend state that the driver should use anytime it calls back into the Direct3D runtime.
Return value
None
Remarks
The driver can use the pfnSetErrorCb callback function to set an error code.
The driver can pass E_OUTOFMEMORY (if the driver runs out of memory) or D3DDDIERR_DEVICEREMOVED (if the device has been removed) in a call to the pfnSetErrorCb function. The Direct3D runtime will determine that any other errors are critical. If the driver passes any errors, including D3DDDIERR_DEVICEREMOVED, the Direct3D runtime will determine that the handle is invalid; therefore, the runtime will not call the DestroyBlendState function to destroy the handle that the hBlendState parameter specifies.
The user-mode display driver is not required to create more than 4,096 unique instances of blend-state objects on a device at one time.
