ID3D12FunctionReflection::GetConstantBufferByIndex method (d3d12shader.h)
Gets a constant buffer by index for a function.
Syntax
ID3D12ShaderReflectionConstantBuffer * GetConstantBufferByIndex(
[in] UINT BufferIndex
);
Parameters
[in] BufferIndex
Type: UINT
Zero-based index.
Return value
Type: ID3D12ShaderReflectionConstantBuffer*
A pointer to a ID3D12ShaderReflectionConstantBuffer interface that represents the constant buffer.
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.
