CalcPrivateShaderSize routine

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 CalcPrivateShaderSize;

SIZE_T APIENTRY CalcPrivateShaderSize(
  D3D10DDI_HDEVICE hDevice,
  __in_ecount(pCode[1]) CONST UINT *pCode,
  __in CONST D3D10DDIARG_STAGE_IO_SIGNATURES *pSignatures
)
{ ... }

Parameters

hDevice

[in] A handle to the display device (graphics context).

pCode

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

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.

Requirements

Version

Available in Windows Vista and later versions of the Windows operating systems.
