ID3DX11Effect::GetConstantBufferByIndex method

Get a constant buffer by index.

Syntax

ID3DX11EffectConstantBuffer* GetConstantBufferByIndex(
   UINT Index
);

Parameters

Index

Type: UINT

A zero-based index.

Return value

Type: ID3DX11EffectConstantBuffer*

A pointer to a ID3DX11EffectConstantBuffer.

Remarks

An effect that contains a variable that will be read/written by an application requires at least one constant buffer. For best performance, an effect should organize variables into one or more constant buffers based on their frequency of update.

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.
