# XPackageFeatureEnumerationCallback

由 [XPackageEnumerateFeatures](/reference/system/xpackage/functions/xpackageenumeratefeatures) 用于枚举每个功能的回调。

## 语法

```cpp theme={null}
bool XPackageFeatureEnumerationCallback(  
         void* context,  
         const XPackageFeature* feature  
)  
```

### 参数

*context*   \_In\_\
类型：void\*

在启动功能枚举时传递给 [XPackageEnumerateFeatures](/reference/system/xpackage/functions/xpackageenumeratefeatures) 的上下文。

*feature*   \_In\_\
类型：[XPackageFeature\*](/reference/system/xpackage/structs/xpackagefeature)

指向描述功能的 [XPackageFeature](/reference/system/xpackage/structs/xpackagefeature) 结构的指针。

### 返回值

类型：bool

返回 true 以继续枚举程序包，返回 false 以停止枚举。

## 备注

此回调函数枚举程序包的 layout.xml 中定义的功能。程序包布局文件中定义的一个重要功能是 `displayName`。`displayName` 显示在游戏的 *Shell* 管理页中。有关 XBOX One 游戏所使用的打包技术的信息，请参阅[打包概述](/build/core-features/common/packaging/overviews/packaging)。
