How can I determine if there are any active tasks?
I have some code that I need to put a mutex into. This code is called both from TBB code and non-TBB code so I don't want to take out the lock if I don't have to. I can't tell how to determine if the TBB scheduler currently has any tasks assigned to it though. I had hoped that tbb_scheduler_init::is_active() would do it but it seems not. It's always true after some TBB code has run. Is this possible?
