CalcPrivateResourceSize(D3D11) routine

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 CalcPrivateResourceSize;

SIZE_T APIENTRY CalcPrivateResourceSize(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D11DDIARG_CREATERESOURCE *pCreateResource
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

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

Version

CalcPrivateResourceSize(D3D11) is supported beginning with the Windows 7 operating system.
