GATE 2023 Exam | CSE | Operating Systems | Semaphores (Binary & Counting) | Free Online Course

5.16. It should be possible to implement general semaphores using binary semaphores. Wecan use the operations semWaitB and semSignalB and two binary semaphores,delay and mutex. Consider the following:void semWait (semaphore s)semWaitB (mutex);S–;if (s < 0) semSignalB (mutex);semWaitB (delay);else SemsignalB (mutex);void semSignal (semaphore s);semWaitB (mutex);S ;if (s <= 0)semSignalB (delay);semSignalB (mutex);Initially, s is set to the desired semaphore value. Each semWait operation decrement
