PFND3D10DDI_CALCPRIVATESHADERSIZE callback function

The CalcPrivateShaderSize 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 shader.

Syntax

PFND3D10DDI_CALCPRIVATESHADERSIZE Pfnd3d10ddiCalcprivateshadersize;

SIZE_T Pfnd3d10ddiCalcprivateshadersize(
  D3D10DDI_HDEVICE Arg1,
  const UINT *pShaderCode,
  const D3D10DDIARG_STAGE_IO_SIGNATURES *Arg3
)
{...}

Parameters

Arg1

hDevice [in]

A handle to the display device (graphics context).

pShaderCode

pShaderCode [in]

An array of CONST UINT tokens that make up the shader code.

Arg3

pSignatures [in]

A pointer to a D3D10DDIARG_STAGE_IO_SIGNATURES structure that makes up the shader's signature.

Return Value

CalcPrivateShaderSize returns the size of the memory region that the driver requires for creating a shader.
