PFND3D11DDI_CALCPRIVATEGEOMETRYSHADERWITHSTREAMOUTPUT callback function

The CalcPrivateGeometryShaderWithStreamOutput(D3D11) 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

PFND3D11DDI_CALCPRIVATEGEOMETRYSHADERWITHSTREAMOUTPUT Pfnd3d11ddiCalcprivategeometryshaderwithstreamoutput;

SIZE_T Pfnd3d11ddiCalcprivategeometryshaderwithstreamoutput(
  D3D10DDI_HDEVICE Arg1,
  const D3D11DDIARG_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT *Arg2,
  const D3D10DDIARG_STAGE_IO_SIGNATURES *Arg3
)
{...}

Parameters

Arg1

hDevice [in]

A handle to the display device (graphics context).

Arg2

pCreateGeometryShaderWithStreamOutput [in]

A pointer to a D3D11DDIARG_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Arg3

pSignatures [in]

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

Return Value

CalcPrivateGeometryShaderWithStreamOutput(D3D11) returns the size of the memory region that the driver requires to create a geometry shader with stream output.

Requirements

   
Minimum supported client CalcPrivateGeometryShaderWithStreamOutput(D3D11) is supported beginning with the Windows 7 operating system.
