ID3DX11EffectShaderVariable::GetInputSignatureElementDesc method

Get an input-signature description.

Syntax

HRESULT GetInputSignatureElementDesc(
   UINT                           ShaderIndex,
   UINT                           Element,
   D3D11_SIGNATURE_PARAMETER_DESC *pDesc
);

Parameters

ShaderIndex

Type: UINT

A zero-based shader index.

Element

Type: UINT

A zero-based shader-element index.

pDesc

Type: D3D11_SIGNATURE_PARAMETER_DESC*

A pointer to a parameter description (see D3D11_SIGNATURE_PARAMETER_DESC).

Return value

Type: HRESULT

Returns one of the following Direct3D 11 Return Codes.

Remarks

An effect contains one or more shaders; each shader has an input and output signature; each signature contains one or more elements (or parameters). The shader index identifies the shader and the element index identifies the element (or parameter) in the shader signature.

Note

The DirectX SDK does not supply any compiled binaries for effects. You must use Effects 11 source to build your effects-type application. For more information about using Effects 11 source, see Differences Between Effects 10 and Effects 11.

Requirements

Requirement	Value
Header	D3dx11effect.h
Library	N/A (An Effects 11 library is available online as shared source.)
