PFND3D11DDI_CALCPRIVATETESSELLATIONSHADERSIZE callback function

Description

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.

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).
