Callback functions for shutdown()?

Hi, I encountered an issue that seems need some customization to the shutdown() function:

I have a separate thread initiated and detached before polyscope::init() -- a server listening from other software for sending geometries in.

The server use a shared_ptr<UIState> which is also used in the main().

Now if I close the main window of polyscope, there's always an error pointing to the ~shared_ptr<UIState>.

I'm not 100% sure what happened there, but it seems the main thread delete the shared_ptr<UIState> before the other thread exit. And when the server tries to delete that shared_ptr, it points to nowhere?

I assume manually exit the separate thread before the main should help.

Lisez le point d’entrée shutdown() ainsi que les chemins de propriété et de durée de vie de UIState décrits dans le rapport. Déterminez comment un hook d’arrêt pourrait permettre au serveur détaché de s’arrêter avant la destruction de l’état partagé, puis vérifiez que la fermeture de la fenêtre principale se termine sans l’erreur shared_ptr signalée.
