         const SHAPE_XMA_CONTEXT* context  
)  
```

<a id="parametersSection" />

### 參數

## 備註

若要取得目前的輸入緩衝區，請使用 [GetShapeXmaCurrentInputBuffer](/zh-TW/reference/audio/shapexmacontext/functions/getshapexmacurrentinputbuffer)。

若要設定目前輸入緩衝區的讀取位移，請使用 [SetShapeXmaInputBufferReadOffset](/zh-TW/reference/audio/shapexmacontext/functions/setshapexmainputbufferreadoffset)。

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。
