Terminating secondary thread from another thread

[pheres]

exit() is a very dangerous solution, because destructor's of automatic objects are not called, so any kind of object-bound resource is not properly freed.

1. use cancellation points and call cancel/join from your main thread, or
2. on threads with endless loop introduce a flag, so the loop is ended if flag is set from main thread. after setting flag call join

Because cancelling a thread calls destructors?

(It doesn't.)

(It doesn't.)

But the thread knows when it possibly gets canceled (because it knows in cancellation points) but it doesn't know when it gets killed by exit()?

But of course I would use the second solution, too.
