pthread_cleanup_push handler not working for SIGINT (Ctrl C)

c, linux, pthreads

Solution

Yes, this is expected, as per man page, `pthread_cleanup_push()` executes in following 3 circumstances:

      1) When a thread is canceled
      2) thread terminates using pthread_exit()
      3) when pthread_cleanup_pop()

To workaround your problem you can register a signal handler for SIGINT, from that handler use `pthread_exit()` or `pthread_cancel()` to execute your handler. Hope this helps!

Problem

I have a code similar to : ``` myThread() { pthread_cleanup_push(CleanupHandler , NULL) while (true) { /* some code here */ } pthread_cleanup_pop(NULL) } static void CleanupHandler(void *arg) { printf("Cleaned\n"); } ``` But if I terminate my application using ^C (SIGINT), the cleanup handler is not working. Is that expected ? What is the workaround to make the CleanupHandler work at ^C ?
