SIZE_T APIENTRY CalcPrivateResourceSize(
  _In_       D3D10DDI_HDEVICE           hDevice,
  _In_ const D3D10DDIARG_CREATERESOURCE *pCreateResource
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCreateResource [in]

A pointer to a D3D10DDIARG_CREATERESOURCE structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Return value

CalcPrivateResourceSize returns the size of the memory region that the driver requires for creating resources.
