## Syntax

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

### Parameters

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

指向 [SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/structs/shape_xma_context.md) 对象的指针。

*buffer*   \_In\_\
Type: void\*

指向重叠相加缓冲区的指针。必须按 128 字节对齐。

### Return value

Type: HRESULT

HRESULT 成功或错误代码。

## Remarks

重叠相加缓冲区的大小必须为:单声道 256 字节,或立体声 512 字节。

若要通过物理地址设置重叠相加缓冲区的地址,请使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer_2.md)。

若要获取重叠相加缓冲区的当前大小,请使用 [GetShapeXmaOverlapAddBuffer](https://docs.xbox.com/zh-CN/reference/audio/shapexmacontext/functions/getshapexmaoverlapaddbuffer.md)。
