# XAppBroadcastUnregisterIsAppBroadcastingChanged

移除應用程式廣播狀態變更事件處理常式。

## 語法

```cpp theme={null}
bool XAppBroadcastUnregisterIsAppBroadcastingChanged(  
         XTaskQueueRegistrationToken token,  
         bool wait  
)  
```

### 參數

*token*   \_In\_\
類型：XTaskQueueRegistrationToken

由 [XAppBroadcastRegisterIsAppBroadcastingChanged](/zh-TW/reference/system/xappcapture/functions/xappbroadcastregisterisappbroadcastingchanged) 建立的事件處理常式權杖。用來取消註冊回呼。

*wait*   \_In\_\
類型：bool

告知取消註冊函式在回呼函式正在執行某些封鎖函式時等待。這可保證此函式傳回後不會再有任何回呼，因此可以安全地關閉。

### 傳回值

類型：bool

## 備註

<Note>在時間敏感執行緒上呼叫此函式並不安全。如需詳細資訊，請參閱[時間敏感執行緒](https://learn.microsoft.com/gaming/gdk/docs/gdk-dev/console-dev/overviews/threads/time-sensitive-threads)。</Note>

每次呼叫 [XAppBroadcastRegisterIsAppBroadcastingChanged](/zh-TW/reference/system/xappcapture/functions/xappbroadcastregisterisappbroadcastingchanged) 之後，都應該在不再需要事件處理常式時呼叫 **AppBroadcastUnregisterIsAppBroadcastingChanged**。若未呼叫此函式，將會導致記憶體流失。此函式會取消註冊由 [XAppBroadcastRegisterIsAppBroadcastingChanged](/zh-TW/reference/system/xappcapture/functions/xappbroadcastregisterisappbroadcastingchanged) 設定的 [XAppBroadcastMonitorCallback](/zh-TW/reference/system/xappcapture/functions/xappbroadcastmonitorcallback)。

## 需求

**標頭：** XAppCapture.h

**程式庫：** xgameruntime.lib

**支援的平台：** Windows、XBOX One 系列主機和 XBOX Series 主機
