    There is no standard, portable way. There may or may not be a 
platform-specific way. For what it's worth, I can't think of anything you 
could do with the information safely other than count the number of threads.

    For example, suppose you get an indication that a particular pthread_id 
is on that list. There are two possibilities. Either you already knew for 
sure that that pthread_id was in use, in which case it tells you nothing you 
didn't already know, or that pthread_id could refer to anything, including a 
thread that ended before you had a chance to look at the pthread_id. In 
either case, how does it help you? You can't use the pthread_id for anything 
because it may no longer be valid.
