void XGameStreamingConnectionStateChangedCallback(
         void* context,
         XGameStreamingClientId client,
         XGameStreamingConnectionState state
)
```

<a id="parametersSection" />

### 参数

类型：void\*

订阅事件时提供的上下文。

*client*   \_In\_\
类型：XGameStreamingClientId

### 返回值

类型：void

<a id="remarksSection" />

## 备注

每当流式处理设备连接或断开连接时，就会调用 `XGameStreamingClientChangedCallback`。

注册后，也会为每个已连接的设备调用此回调。

通过 [XGameStreamingRegisterConnectionStateChanged](/reference/system/xgamestreaming/functions/xgamestreamingregisterconnectionstatechanged) 注册后，也会为已连接的设备调用回调。
