ID3D12ShaderReflection::GetConstantBufferByIndex method (d3d12shader.h)

Gets a constant buffer by index.

Syntax

ID3D12ShaderReflectionConstantBuffer * GetConstantBufferByIndex(
  [in] UINT Index
);

Parameters

[in] Index

Type: UINT

Zero-based index.

Return value

Type: ID3D12ShaderReflectionConstantBuffer*

A pointer to a constant buffer (see ID3D12ShaderReflectionConstantBuffer Interface).

Remarks

A constant buffer supplies either scalar constants or texture constants to a shader. A shader can use one or more constant buffers. For best performance, separate constants into buffers based on the frequency they are updated.

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