ID3D11ShaderReflection::GetConstantBufferByIndex Method

Get a constant buffer by index.

Syntax

public:
ID3D11ShaderReflectionConstantBuffer* GetConstantBufferByIndex(
         UINT Index
)

Parameters

Index
Type: UINT

[in] Zero-based index.

Return value

Type: ID3D11ShaderReflectionConstantBuffer *

A pointer to a constant buffer (see ID3D11ShaderReflectionConstantBuffer 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.
