PFND3D11DDI_CALCPRIVATERESOURCESIZE callback function (d3d10umddi.h)
The CalcPrivateResourceSize(D3D11) 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).
Syntax
PFND3D11DDI_CALCPRIVATERESOURCESIZE Pfnd3d11ddiCalcprivateresourcesize;
SIZE_T Pfnd3d11ddiCalcprivateresourcesize(
D3D10DDI_HDEVICE unnamedParam1,
const D3D11DDIARG_CREATERESOURCE *unnamedParam2
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pCreateResource [in]
A pointer to a D3D11DDIARG_CREATERESOURCE structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.
Return value
CalcPrivateResourceSize(D3D11) returns the size of the memory region that the driver requires to create resources.
