)  
```

<a id="ID4EH" />

### 参数

*pData*\
类型：XTF\_OUTPUT\_DEBUG\_STRING\_DATA \*

## 备注

此标题定义的函数处理开发主机上游戏生成的调试字符串。此函数决定在调用 [IXtfDebugMonitorClient::Start](/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/start-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m) 后检测到的每个调试字符串将如何处理。标题定义的方法必须与 **IXtfDebugMonitorCallback::OnOutputDebugString** 方法的返回值和参数相匹配。

## 要求

**头文件：** xtfdebugmonitor.h

**库：** xtfdebugmonitor.lib

**支持的平台：** Windows（适用于 XBOX 主机工具）
