# XGameStreamingClientPropertiesChangedCallback

每当连接的流式处理客户端设备的属性发生更改时调用的回调函数。首次注册时，也会为所有连接的设备调用回调。

## 语法

```cpp theme={null}
void XGameStreamingClientPropertiesChangedCallback(  
         void* context,  
         XGameStreamingClientId client,  
         uint32_t updatedPropertiesCount,  
         XGameStreamingClientProperty* updatedProperties  
)
```

### 参数

*context*   \_In\_\
类型：void\*

指向事件注册时提供的上下文的指针。

*client*   \_In\_\
类型：XGameStreamingClientId

属性已更改的客户端。

*updatedPropertiesCount*   \_In\_\
类型：uint32\_t

客户端上已更改的属性数量。

*updatedProperties*   \_In\_reads\_(updatedPropertiesCount)\
类型：[XGameStreamingClientProperty\*](/reference/system/xgamestreaming/enums/xgamestreamingclientproperty)

指向已更改客户端属性标识符的指针。

### 返回值

类型：void

## 备注

每当流式处理客户端设备的一个或多个属性发生更改时，就会调用 `XGameStreamingClientPropertiesChangedCallback`。设备连接后，将针对适用于该设备的每个属性调用回调。

在通过 [XGameStreamingRegisterClientPropertiesChanged](/reference/system/xgamestreaming/functions/xgamestreamingregisterclientpropertieschanged) 初次注册回调函数时，将针对适用于该设备的每个属性调用回调。

若要注销回调函数，请使用 [XGameStreamingUnregisterClientPropertiesChanged](/reference/system/xgamestreaming/functions/xgamestreamingunregisterclientpropertieschanged)。

## 要求

**标头：** xgamestreaming.h

**库：** xgameruntime.lib

**支持的平台：** Windows、XBOX One 系列主机和 XBOX Series 主机
