    If the thread is joinable, you can call pthread_join()
on it.  When pthread_join() returns, the thread has exited.

    If the thread is detached, there's no reliable way I
know of to tell whether it has exited.  That's usually the
wrong question, though: ordinarily, what you really care
about is whether it has finished its work.  You can arrange
any number of ways to figure that out -- have the thread
put its "work product" on a queue, or post a semaphore, or
whatever makes sense in terms of the thread's role in the
entire program's function.
