## 語法

```cpp theme={null}
UINT32 GetShapeXmaOutputBufferReadOffset(  
         const SHAPE_XMA_CONTEXT* context  
)  
```

### 參數

*context*   \_In\_\
類型：[SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context.md)\*

[SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/structs/shape_xma_context.md) 物件的指標。

### 傳回值

類型：UINT32

從輸出緩衝區開頭算起的位移 (以位元組為單位)。

## 備註

若要設定輸出緩衝區的讀取位移，請使用 [SetShapeXmaOutputBufferReadOffset](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/functions/setshapexmaoutputbufferreadoffset.md)。

若要取得輸出緩衝區的寫入位移，請使用 [GetShapeXmaOutputBufferWriteOffset](https://docs.xbox.com/zh-TW/reference/audio/shapexmacontext/functions/getshapexmaoutputbufferwriteoffset.md)。
