## 語法

```cpp theme={null}
HRESULT SetShapeXmaInputBuffer0Size(  
         SHAPE_XMA_CONTEXT* context,  
         UINT32 size  
)  
```

<a id="parametersSection" />

### 參數

*context*   \_Inout\_\
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。

*size*   \
類型：UINT32

## 備註

若要設定右側輸入緩衝區的大小，請使用 [SetShapeXmaInputBuffer1Size](/zh-TW/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1size)。

若要取得左側輸入緩衝區的大小，請使用 [GetShapeXmaInputBuffer0Size](/zh-TW/reference/audio/shapexmacontext/functions/getshapexmainputbuffer0size)。

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。
