# SetShapeXmaOutputBufferReadOffset

設定輸出緩衝區的讀取位移。

<a id="syntaxSection" />

## 語法

```cpp theme={null}
HRESULT SetShapeXmaOutputBufferReadOffset(  
         SHAPE_XMA_CONTEXT* context,  
         UINT32 offset  
)  
```

<a id="parametersSection" />

### 參數

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

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

*offset*   \
類型: UINT32

從輸出緩衝區開頭算起的位移 (以位元組為單位)。必須是 256 的倍數。

## 備註

若要取得輸出緩衝區的讀取位移，請使用 [GetShapeXmaOutputBufferReadOffset](/zh-TW/reference/audio/shapexmacontext/functions/getshapexmaoutputbufferreadoffset)。

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。
