PFND3D12DDI_CALCPRIVATEDEPTHSTENCILSTATESIZE callback function (d3d12umddi.h)

The CalcPrivateDepthStencilStateSize 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 depth stencil state.

Syntax

PFND3D12DDI_CALCPRIVATEDEPTHSTENCILSTATESIZE Pfnd3d12ddiCalcprivatedepthstencilstatesize;

SIZE_T Pfnd3d12ddiCalcprivatedepthstencilstatesize(
  D3D12DDI_HDEVICE unnamedParam1,
  const D3D12DDI_DEPTH_STENCIL_DESC *unnamedParam2
)
{...}

Parameters

unnamedParam1

A handle to the display device (graphics context).

unnamedParam2

A pointer to a D3D12DDI_DEPTH_STENCIL_DESC structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Return value

Returns the size of the memory region that the driver requires for creating a depth stencil state.
