Are there any functions in Qt that are considered async-handler-safe?
No, as any of them may allocate memory.See https://doc.qt.io/qt-5/unix-signals.html for the textbook solution (self pipe trick).
On Linux you can also use signalfd(2) to achieve the same without the burden of a custom signal handler.
