> XblMultiplayerManagerGameSessionSetSynchronizedHost

# XblMultiplayerManagerGameSessionSetSynchronizedHost

使用 `XblMultiplayerSessionWriteMode::SynchronizedUpdate` 设置游戏会话的主机。

## 语法

```cpp theme={null}
HRESULT XblMultiplayerManagerGameSessionSetSynchronizedHost(  
         const char* deviceToken,  
         void* context  
)  
```

### 参数

*deviceToken*   \_In\_\
类型：char\*

主机的设备令牌。

*context*   \_In\_opt\_\
类型：void\*

可选。用于将 [XblMultiplayerEvent](/reference/live/xsapi-c/multiplayer_manager_c/structs/xblmultiplayerevent) 关联到发起调用的应用程序定义的数据。

### 返回值

类型：HRESULT

此 API 操作的 HRESULT 返回代码。

## 备注

此函数设置游戏会话的主机。使用此函数可确保原子性，并解决设备之间尝试同时设置主机所产生的任何冲突。<br />如果由于冲突而发生争用情况，服务可能会拒绝设置主机的请求。如果请求被拒绝，服务将返回 `HTTP_E_STATUS_PRECOND_FAILED`。如果发生冲突，请重新评估更改主机的需要，如有必要，再次调用此函数以重新提交请求。<br />此函数的结果作为多人游戏事件传递，事件类型设置为 `XblMultiplayerEventType::SynchronizedHostWriteCompleted`。你可以调用 [XblMultiplayerManagerDoWork](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagerdowork) 检索多人游戏事件。请注意，主机设备令牌是从会话成员的安全设备地址生成的，因此在调用此方法之前，请确保为所需的主机设置了安全设备地址。
