ID3D11DeviceContext::GSSetShader method (d3d11.h)

Set a geometry shader to the device.

Syntax

void GSSetShader(
  [in, optional] ID3D11GeometryShader *pShader,
  [in, optional] ID3D11ClassInstance  * const *ppClassInstances,
                 UINT                 NumClassInstances
);

Parameters

[in, optional] pShader

Type: ID3D11GeometryShader*

Pointer to a geometry shader (see ID3D11GeometryShader). Passing in NULL disables the shader for this pipeline stage.

[in, optional] ppClassInstances

Type: ID3D11ClassInstance*

A pointer to an array of class-instance interfaces (see ID3D11ClassInstance). Each interface used by a shader must have a corresponding class instance or the shader will get disabled. Set ppClassInstances to NULL if the shader does not use any interfaces.

NumClassInstances

Type: UINT

The number of class-instance interfaces in the array.

Return value

None

Remarks

The method will hold a reference to the interfaces passed in. This differs from the device state behavior in Direct3D 10.

The maximum number of instances a shader can have is 256.
