# GetShapeXmaOverlapAddBuffer

取得重疊相加 (overlap-add) 緩衝區的位址。

<a id="syntaxSection" />

## 語法

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

<a id="parametersSection" />

### 參數

*context*   \_In\_\
類型：[SHAPE\_XMA\_CONTEXT](/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context)\*

指向 [SHAPE\_XMA\_CONTEXT](/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context) 物件的指標。

<a id="retvalSection" />

### 傳回值

類型：void\*

指向重疊相加緩衝區的指標。

<a id="remarksSection" />

## 備註

重疊相加緩衝區的大小，單聲道為 256 位元組，立體聲為 512 位元組。

若要使用指標設定重疊相加緩衝區的位址，請使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, void\*)](/zh-TW/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer)。

若要使用實體位址設定重疊相加緩衝區的位址，請使用 [SetShapeXmaOverlapAddBuffer(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](/zh-TW/reference/audio/shapexmacontext/functions/setshapexmaoverlapaddbuffer_2)。

如需詳細資訊，請參閱 [SHAPE 概觀](/zh-TW/build/console-features/audio/overviews/shape-overview)中的 [XMA](/zh-TW/build/console-features/audio/overviews/shape-overview#ID4EYD) 一節。
