The CalcPrivateBlendStateSize function determines the size of the user-mode display driver's private region of memory (that is, the size of internal driver structures, not the size of the resource video memory) for a blend state.
Syntax
PFND3D10DDI_CALCPRIVATEBLENDSTATESIZE Pfnd3d10ddiCalcprivateblendstatesize;
SIZE_T Pfnd3d10ddiCalcprivateblendstatesize(
D3D10DDI_HDEVICE unnamedParam1,
const D3D10_DDI_BLEND_DESC *unnamedParam2
)
{...}
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 calculate the size of the memory region.
Return value
CalcPrivateBlendStateSize returns the size of the memory region that the driver requires for creating a blend state.
