# XblMultiplayerManagerLobbySessionConstants

检索与大厅会话关联的会话常量。

## 语法

```cpp theme={null}
const XblMultiplayerSessionConstants* XblMultiplayerManagerLobbySessionConstants(  
)  
```

### 参数

### 返回值

类型：const XblMultiplayerSessionConstants\*

指向大厅会话的会话常量的指针，如果大厅会话不存在则为 null。返回指针的内存在下次调用 [XblMultiplayerManagerDoWork](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagerdowork) 之前保持有效。

## 备注

如果多人游戏管理器中存在大厅会话，此函数将检索指向大厅会话的会话常量的指针。会话常量包含由用于大厅会话的会话模板定义的常量，例如会话可见性和会话功能。与会话属性不同，会话常量只能通过会话模板设置，并在创建大厅会话时设置。有关会话常量的详细信息，请参阅[多人游戏会话高级主题](/services/xbox-services/multiplayer/mpsd/concepts/live-mpsd-details)。
