The CreateGeometryShaderWithStreamOutput(D3D11) function creates a geometry shader with stream output.

Syntax

PFND3D11DDI_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT Pfnd3d11ddiCreategeometryshaderwithstreamoutput;

void Pfnd3d11ddiCreategeometryshaderwithstreamoutput(
  D3D10DDI_HDEVICE unnamedParam1,
  const D3D11DDIARG_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT *unnamedParam2,
  D3D10DDI_HSHADER unnamedParam3,
  D3D10DDI_HRTSHADER unnamedParam4,
  const D3D10DDIARG_STAGE_IO_SIGNATURES *unnamedParam5
)
{...}

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

unnamedParam2

pCreateGeometryWithShaderOutput [in]

A pointer to a D3D11DDIARG_CREATEGEOMETRYSHADERWITHSTREAMOUTPUT structure that describes the parameters that the user-mode display driver uses to create a geometry shader with stream output.

unnamedParam3

hShader [in]

A handle to the driver's private data for the geometry shader with stream output. The driver returns the size, in bytes, of the memory region that the Microsoft Direct3D runtime must allocate for the private data from a call to the driver's CalcPrivateGeometryShaderWithStreamOutput(D3D11) function. The handle is just a pointer to a region of memory, the size of which the driver requested. The driver uses this region of memory to store internal data structures that are related to its shader object.

unnamedParam4

hRTShader [in]

A handle to the geometry shader with stream output that the driver should use when it calls back into the Direct3D runtime.

unnamedParam5

pSignatures [in]

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

Return value

None

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code.

The driver can pass E_OUTOFMEMORY (if the driver runs out of memory) or D3DDDIERR_DEVICEREMOVED (if the device is removed) in a call to the pfnSetErrorCb function. The Direct3D runtime determines that any other errors are critical. If the driver passes any errors, which includes D3DDDIERR_DEVICEREMOVED, the Direct3D runtime determines that the handle is invalid; therefore, the runtime does not call the DestroyShader function to destroy the handle that the hShader parameter specifies.
