[Boost-users] is it possible to initialize thread local storage automatically?

Hi! I'm looking for a method to execute some code for each thread starting. It suffices to run that code for each boost::thread. I want to initialize some thread local storage for each thread automatically. The creating(!) thread shall supply an initial value and the created(!) thread shall receive this value, essentially a copy of some thread local variable. That is the new thread shall create a copy of the same variable which the creating thread has. Is that possible using boost::thread? I hope my explaination is clear enough. Frank
