pthread_kill Example

This short program deliberately kills a thread after pthread_join so it may cause SEGV on some targets.

Compiling

gcc -pthread thread1.c

  pthread_t th;
  int rc = 0;

    abort();
  }
  if ((rc = pthread_kill(th, SIGTERM)) != 0) {
    printf("Error in pthread_kill; errno:%x, message:%s\n", rc, strerror(rc));
