ID3DX11EffectBlendVariable::GetBackingStore method

Get a pointer to a blend-state variable.

Syntax


HRESULT GetBackingStore(
   UINT             Index,
   D3D11_BLEND_DESC *pBlendDesc
);

Parameters

Index

Type: UINT

Index into an array of blend-state descriptions. If there is only one blend-state variable in the effect, use 0.

pBlendDesc

Type: D3D11_BLEND_DESC*

A pointer to a blend-state description (see D3D11_BLEND_DESC).

Return value

Remarks

Effect variables are saved in memory in the backing store; when a technique is applied, the values in the backing store are copied to the device. Backing store data can used to recreate the variable when necessary.

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.
