# GetShapeXmaOverlapAddBuffer

获取重叠相加缓冲区的地址。

<a id="syntaxSection" />

## 语法

```cpp theme={null}
void* GetShapeXmaOverlapAddBuffer(  
         const SHAPE_XMA_CONTEXT* context  
)  
```

<a id="parametersSection" />

### 参数

*context*   \_In\_\
Type: [SHAPE\_XMA\_CONTEXT](/reference/audio/shapexmacontext/structs/shape_xma_context)\*

指向 [SHAPE\_XMA\_CONTEXT](/reference/audio/shapexmacontext/structs/shape_xma_context) 对象的指针。

<a id="retvalSection" />

### 返回值

Type: void\*

指向重叠相加缓冲区的指针。

<a id="remarksSection" />

## 备注

重叠相加缓冲区的大小为单声道 256 字节或立体声 512 字节。

若要通过指针设置重叠相加缓冲区的地址,请使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, void\*)](/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer)。

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)](/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer_2)。

有关详细信息,请参阅 [Overview of SHAPE](/build/console-features/audio/overviews/shape-overview) 的 [XMA](/build/console-features/audio/overviews/shape-overview#ID4EYD) 部分。
