CalcPrivateGeometryShaderWithStreamOutput routine

The CalcPrivateGeometryShaderWithStreamOutput 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 geometry shader with stream output.

Syntax


PFND3D10DDI_CALCPRIVATEGEOMETRYSHADERWITHSTREAMOUTPUT CalcPrivateGeometryShaderWithStreamOutput;

SIZE_T APIENTRY CalcPrivateGeometryShaderWithStreamOutput(
  _In_       D3D10DDI_HDEVICE                                 hDevice,
  _In_ const D3D10DDIARG_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT *pCreateGeometryShaderWithStreamOutput,
  _In_ const D3D10DDIARG_STAGE_IO_SIGNATURES                  *pSignatures
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCreateGeometryShaderWithStreamOutput [in]

A pointer to a D3D10DDIARG_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

pSignatures [in]

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

Return value

CalcPrivateGeometryShaderWithStreamOutput returns the size of the memory region that the driver requires for creating a geometry shader with stream output.

Requirements

Target platform

Version

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