PFND3D11DDI_CALCPRIVATETESSELLATIONSHADERSIZE callback function (d3d10umddi.h)

The CalcPrivateTessellationShaderSize 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 hull or ___domain shader.

Syntax

PFND3D11DDI_CALCPRIVATETESSELLATIONSHADERSIZE Pfnd3d11ddiCalcprivatetessellationshadersize;

SIZE_T Pfnd3d11ddiCalcprivatetessellationshadersize(
  D3D10DDI_HDEVICE unnamedParam1,
  const UINT *pShaderCode,
  const D3D11DDIARG_TESSELLATION_IO_SIGNATURES *unnamedParam3
)
{...}

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

pShaderCode

unnamedParam3

pCode [in]

An array of CONST UINT tokens that form the hull-shader code or ___domain-shader code.

Return value

CalcPrivateTessellationShaderSize returns the size of the memory region that the driver requires to create a hull or ___domain shader.

Remarks

The Direct3D runtime calls the driver's CalcPrivateTessellationShaderSize function to calculate the size of the memory region for a hull or ___domain shader. This is similar to the way that the Direct3D runtime calls the driver's CalcPrivateShaderSize function to calculate the size of the memory region for a pixel, vertex, or geometry shader (that is, a geometry shader without stream output).
