关闭应用程序时是否需要终止线程？

Question

当我的应用程序即将关闭时，UI线程是否应该“告诉”其他线程终止，并在关闭应用程序之前等待它们终止？

Answer 1

To clarify; when your main thread (the one that started with your process) returns from the WinMain function, the process will exit and all your other threads will terminate automatically.

It depends what your other threads are doing as to how important it is that you shut them down cleanly.

For example, if the other threads are potentially writing to disk, then you absolutely should shut them down cleanly. If they're just doing calculations then it probably wouldn't hurt to let them die automatically when your main thread exits.

However it's always good programming practice to clean up after yourself (free any memory allocations, etc).
