PFND3D11DDI_CALCPRIVATERESOURCESIZE callback function

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 Arg1,
  const D3D11DDIARG_CREATERESOURCE *Arg2
)
{...}

Parameters

Arg1

hDevice [in]

A handle to the display device (graphics context).

Arg2

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.

Requirements

   
Minimum supported client CalcPrivateResourceSize(D3D11) is supported beginning with the Windows 7 operating system.
Target Platform Desktop
Header d3d10umddi.h (include D3d10umddi.h)
