Usage example of boost::condition::timed_wait
Actually, I finally found a link with full example here. With a bit of adapting, this seems to be the call.
boost::system_time const timeout=boost::get_system_time()+ boost::posix_time::milliseconds(35000);boost::mutex::scoped_lock lock(the_mutex);if(the_condition_variable.timed_wait(lock,timeout,&CondFulfilled)){ <cond fulfilled code>}else{ <timeout code>}bool CondFulfilled() { ... }
