# SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)

Définit l'adresse de la mémoire tampon de chevauchement-addition (overlap-add).

<a id="syntaxSection" />

## Syntaxe

```cpp theme={null}
HRESULT SetShapeXmaOverlapAddBuffer(  
         SHAPE_XMA_CONTEXT* context,  
         APU_ADDRESS buffer  
)  
```

<a id="parametersSection" />

### Paramètres

*context*   \_Inout\_\
Type : [SHAPE\_XMA\_CONTEXT](/fr-CA/reference/audio/shapexmacontext/structs/shape_xma_context)\*

Pointeur vers un objet [SHAPE\_XMA\_CONTEXT](/fr-CA/reference/audio/shapexmacontext/structs/shape_xma_context).

*buffer*   \_In\_\
Type : APU\_ADDRESS

Adresse physique de la mémoire tampon de chevauchement-addition.

<a id="retvalSection" />

### Valeur de retour

Type : HRESULT

Code de réussite ou d'erreur HRESULT.

<a id="remarksSection" />

## Remarques

La taille de la mémoire tampon de chevauchement-addition doit être de 256 octets en mono ou de 512 octets en stéréo.

Pour définir l'adresse de la mémoire tampon de chevauchement-addition à l'aide d'un pointeur, utilisez [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, void\*)](/fr-CA/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer).

Pour obtenir la taille actuelle de la mémoire tampon de chevauchement-addition, utilisez [GetShapeXmaOverlapAddBuffer](/fr-CA/reference/audio/shapexmacontext/functions/getshapexmaoverlapaddbuffer).

Pour plus d'informations, consultez la section [XMA](/fr-CA/build/console-features/audio/overviews/shape-overview#ID4EYD) de la [Vue d'ensemble de SHAPE](/fr-CA/build/console-features/audio/overviews/shape-overview).
