PFND3D10DDI_CALCPRIVATEELEMENTLAYOUTSIZE callback function (d3d10umddi.h)
The CalcPrivateElementLayoutSize 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 an element layout.
Syntax
PFND3D10DDI_CALCPRIVATEELEMENTLAYOUTSIZE Pfnd3d10ddiCalcprivateelementlayoutsize;
SIZE_T Pfnd3d10ddiCalcprivateelementlayoutsize(
D3D10DDI_HDEVICE unnamedParam1,
const D3D10DDIARG_CREATEELEMENTLAYOUT *unnamedParam2
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pCreateElementLayout [in]
A pointer to a D3D10DDIARG_CREATEELEMENTLAYOUT structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.
Return value
CalcPrivateElementLayoutSize returns the size of the memory region that the driver requires for creating an element layout.
