# SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, void\*)

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

## Syntaxe

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

### Paramètres

*context*   \_Inout\_\
Type : [SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/fr-CA/reference/audio/shapexmacontext/structs/shape_xma_context.md)\*

Pointeur vers un objet [SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/fr-CA/reference/audio/shapexmacontext/structs/shape_xma_context.md).

*buffer*   \_In\_\
Type : void\*

Pointeur vers la mémoire tampon de chevauchement-addition. Doit être alignée sur 128 octets.

### Valeur de retour

Type : HRESULT

Code de réussite ou d'erreur HRESULT.

## 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'une adresse physique, utilisez [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](https://docs.xbox.com/fr-CA/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer_2.md).

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