Hi, thank you all for your help. It was a basically missunderstanding of join() on my side. The message of Nat Goodspeed helped me to discover that. So, lets close this thread.

Than you can call join on entire group, where the caller thread blocks until all threads are finished. -----Original Message----- From: Nat Goodspeed [mailto:ngoodspeed@solidworks.com] Sent: Monday, November 06, 2006 5:57 PM To: boost-users@lists.boost.org Subject: Re: [Boost-users] [Threads] Problem with starting a sub thread thread
I understood and experienced that the main thread blocks. But how can
it
join other threads, if it is blocked? That doesn't seem consistent to me.
[Nat] Usually one wouldn't create a thread and then immediately join() it. The net effect of that would seem to be an expensive function call. Usually if you want a new thread to run in parallel with the thread that created it, you let both threads run for a while before one thread attempts to join() the other. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
