## 备注

<Note>在时间敏感型线程上调用此函数不安全。
有关详细信息，请参阅[时间敏感型线程](https://learn.microsoft.com/gaming/gdk/docs/gdk-dev/console-dev/overviews/threads/time-sensitive-threads)。</Note>

此函数取消注册由 [XStorePackageLicenseLostCallback](/reference/system/xstore/functions/xstorepackagelicenselostcallback) 定义的回调函数。
使用 [XStoreRegisterPackageLicenseLost](/reference/system/xstore/functions/xstoreregisterpackagelicenselost) 生成的相同 **XTaskQueueRegistrationToken** 来取消注册回调函数。
为避免内存泄漏，每个使用 [XStoreRegisterPackageLicenseLost](/reference/system/xstore/functions/xstoreregisterpackagelicenselost) 注册的函数在不再需要回调函数时必须通过 **XStoreUnregisterPackageLicenseLost** 取消注册。

有关使用示例，请参阅 [XStoreAcquireLicenseForPackageAsync](/reference/system/xstore/functions/xstoreacquirelicenseforpackageasync)。

## 要求

**头文件：** XStore.h（包含在 XGameRuntime.h 中）
