hi all, is there a way to get a reference to the function object used by a boost::thread object?? when you create a new thread and feed it a function object it copies it and then starts a new thread of execution on this object.. well, I would like to send messages to the object in which the thread is running but I don't know how to do it with boos.threads...

I use the pimpl idiom with a boost::shared_ptr<> doing the trick. It's not very clean, but here goes my example: --------------------------------------------------------- #include #include #include #include #include <iostream> #include class counter_thread { public: counter_thread(): _pimpl(new counter_thread_impl) {} void Print() { _pimpl->Print(); } void Incr() { _pimpl->Incr(); } void operator()() { _pimpl->Run(); } private: class counter_thread_impl { public: counter_thread_impl() : _counter(0) { } void Run() { for(unsigned i=0; i<10;++i) { Print(); Incr(); boost::xtime xt; boost::xtime_get(&xt, boost::TIME_UTC); xt.sec += 1; boost::thread::sleep(xt); } } void Print() { boost::recursive_mutex::scoped_lock block_now(mutex); std::cout << "Counter: " << _counter << std::endl; } void Incr() { boost::recursive_mutex::scoped_lock block_now(mutex); ++_counter; } private: unsigned _counter; boost::recursive_mutex mutex; }; boost::shared_ptr _pimpl; }; int main(int argc, char* argv[]) { counter_thread theCounter; boost::thread threadManager(theCounter); for(unsigned i=0; i<10;++i) { theCounter.Print(); boost::xtime xt; boost::xtime_get(&xt, boost::TIME_UTC); xt.sec += 1; boost::thread::sleep(xt); } threadManager.join(); } --------------------------------------------------------- Note that, in main(), theCounter.Print() prints the correct value.
