         bool valid  
)  
```

<a id="parametersSection" />

## 備註

若要設定右側輸入緩衝區的有效性旗標，請使用 [SetShapeXmaInputBuffer1Valid](/zh-TW/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1valid)。

若要取得左側輸入緩衝區的有效性旗標，請使用 [GetShapeXmaInputBuffer0Valid](/zh-TW/reference/audio/shapexmacontext/functions/getshapexmainputbuffer0valid)。
