The CalcPrivateQuerySize 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 query.
Syntax
PFND3D10DDI_CALCPRIVATEQUERYSIZE Pfnd3d10ddiCalcprivatequerysize;
SIZE_T Pfnd3d10ddiCalcprivatequerysize(
D3D10DDI_HDEVICE unnamedParam1,
const D3D10DDIARG_CREATEQUERY *unnamedParam2
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pCreateQuery [in]
A pointer to a D3D10DDIARG_CREATEQUERY structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.
Return value
CalcPrivateQuerySize returns the size of the memory region that the driver requires for creating a query.
