# XblMultiplayerSessionPropertiesSetJoinRestriction

限制谁可以加入 “open” 会话。（对保留没有影响，这意味着它对 “private” 和 “visible” 会话没有影响。）

## 语法

```cpp theme={null}
void XblMultiplayerSessionPropertiesSetJoinRestriction(  
         XblMultiplayerSessionHandle handle,  
         XblMultiplayerSessionRestriction joinRestriction  
)  
```

### 参数

*handle*   \_In\_\
类型: [XblMultiplayerSessionHandle](/reference/live/xsapi-c/multiplayer_c/handles/xblmultiplayersessionhandle)

多人游戏会话的句柄。

*joinRestriction*   \_In\_\
类型: [XblMultiplayerSessionRestriction](/reference/live/xsapi-c/multiplayer_c/enums/xblmultiplayersessionrestriction)

新的加入限制值。

### 返回值

类型: void

## 备注

默认为 “none”。如果为 “local”，则只有其令牌 DeviceId 与已在会话中的其他人相匹配且 “active”: true 的用户可以加入。如果为 “followed”，则只有本地用户（如上定义）和会话中现有（非保留）成员关注的用户可以在没有保留的情况下加入。

## 要求

**头文件:** multiplayer\_c.h
