Non-blocking pthread_join

Question

I\'m coding the shutdown of a multithreaded server.If everything goes as it should all the threads exit by their own, but there\'s a small chance that a thread gets stuck.In

Answer 1

The 'pthread_join' mechanism is a convenience to be used if it happens to do exactly what you want. It doesn't do anything you couldn't do yourself, and where it's not exactly what you want, code exactly what you want.

There is no real reason you should actually care whether a thread has terminated or not. What you care about is whether the work the thread was doing is completed. To tell that, have the thread do something to indicate that it is working. How you do that depends on what is ideal for your specific problem, which depends heavily on what the threads are doing.

Start by changing your thinking. It's not a thread that gets stuck, it's what the thread was doing that gets stuck.
