There are only two ways to do this: either wake the other thread regularly based on a timer, and hope that the chosen interval and accuracy are enough to keep the buffer (empty|full) OR wake the other thread as needed. this second option requires some sort of communication channel to the thread to wake it, which could be (on linux) any of a pthread_condvar, a semaphore, a FIFO/pipe, and eventfd, etc. etc.
