PFND3D11DDI_CALCPRIVATEGEOMETRYSHADERWITHSTREAMOUTPUT callback function (d3d10umddi.h)
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 unnamedParam1,
const D3D11DDIARG_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT *unnamedParam2,
const D3D10DDIARG_STAGE_IO_SIGNATURES *unnamedParam3
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
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.
unnamedParam3
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.
