How to exit thread safely?

[utiao]

I have two working thread. When I exit one thread, I want to exit another thread. Now, I can't do that. How do I?
thanks!

In the simplest way, you can set a flag to indicate to the other thread that it has terminated. As for the other thread, it should be looping and checking the flag. So when it find that the flag is set, it should stop entering the loop and terminate itself .

Essentially, one thread will end up waiting for one or more threads to terminate.

So I can set a flag in every thread. When I want to exit the main thread, I must check the every flag whether they have been set.

Hi,

You can do this:
1) Create a Global Manual Reset Event (say X), Initially Non Signalled.
2) In every Thread, Inside the Loop, use WaitForSingleObject(X, 50 ms) ;
3) Check if Return Value of WaitForSingleObject() equals WAIT_OBJECT_0, then Cleanup and Exit the Thread.

When You want to Close all the Threads, use SetEvent(X) ;
