I want a worker thread to terminate if there is nothing to do. If there is something to do again and the worker thread has terminated I need to create a new one. Now I wonder if I can use boost::thread to detect whether the thread is running or not.
The reason boost::thread doesn't provide you with an "is_running" function, is that it would be nearly impossible to write it correctly. Example: main thread starts worker. worker starts work. main thread calls is_running which returns true. now, before main thread can execute next statement, worker thread exits. main thread tries to send more work to worker, who is gone.
