That's the idea, at least.

You can either save the cookie_t ID (this is the preferred solution,
since it's guaranteed to be correct), or request a list of all alarms
happening in a specific time interval (using alarm_event_query), then
iterate the list of cookies (retrieving each alarm_event_t with
alarm_event_get) and see if the exec_name or dbus_name matches your
application (as mentioned, this is not 100% fail-safe; think of
cron-like execution schedulers for instance).

No, alarms keep working even when you quit your application.
