BUT, that cannot be used to prioritize a thread. While you block a thread using rtlevent, it can only be unblocked from another thread. While you use sleep(), it still get time share of the CPU, only that it does nothing until sleep finishes, right? That way, it only consume a tiny amount of computing power while sleeping. This, in my view, is the price I have to pay to achieve my purpose?
