Hi, I have created a thread pool library which maintains a worker thread queue and a work queue. Any Application class using this library passes functors to ThreadPool. I am using a ThreadGroup to manage all threads. I use the thread_group.join_all(), to wait for all threads to finish before the main thread exits. But on joining the threads in the thread_group, the main thread fails to exit. Am i missing something. -- View this message in context: http://www.nabble.com/Main-thread-not-exiting-tp20264225p20264225.html Sent from the Boost - Users mailing list archive at Nabble.com.
