# XblSocialAddSocialRelationshipChangedHandler

注册事件处理程序，用于在注册用户引发社交关系更改时接收通知。

## 语法

```cpp theme={null}
XblFunctionContext XblSocialAddSocialRelationshipChangedHandler(  
         XblContextHandle xboxLiveContext,  
         XblSocialRelationshipChangedHandler handler,  
         void* handlerContext  
)  
```

### 参数

*xboxLiveContext*   \_In\_\

接收通知的回调函数。

*handlerContext*   \_In\_opt\_\
类型：void\*

传回给处理程序的客户端上下文指针。

### 返回值
