How to get success/failure in case of thread

[vivek at cs.unipune.ernet.in]

Hi all,
  I am trying to learn using threads  in python. But the main problem I am 
facing is how to check whether the function called using a thread succeeded or
failed. like when I call:
  import thread
  thread.start_new_thread(my_func,(args,))

here my_func will return true/1 on success and false/0 on failure. How can I
check whether the function failed/succeeded ???

TIA and Kind Regards
