  • Article

Gets an input-parameter description for a shader.

Syntax

HRESULT GetInputParameterDesc(
  [in]  UINT                           ParameterIndex,
  [out] D3D12_SIGNATURE_PARAMETER_DESC *pDesc
);

Parameters

[in] ParameterIndex

Type: UINT

A zero-based parameter index.

[out] pDesc

Type: D3D12_SIGNATURE_PARAMETER_DESC*

A pointer to a shader-input-signature description. See D3D12_SIGNATURE_PARAMETER_DESC.

Return value

Type: HRESULT

An input-parameter description is also called a shader signature. The shader signature contains information about the input parameters such as the order or parameters, their data type, and a parameter semantic.

This method's interface is hosted in the out-of-box DLL D3DCompiler_xx.dll.
