in your perspective, what makes counting semaphore primitives a good concurrency mechanism?

struct semaphore { int count; queueType queue; }; void semWait (semaphore s) s.count--; if (s.count < 0) { /* place this process in s.queue */; /* block this process */; void semSignal (semaphore s) { s.count++; if (s.count<= 0) { /* remove a process P from s.queue */; /* place process P on ready list */;
Transcribed Image Text:struct semaphore { int count; queueType queue; }; void semWait (semaphore s) s.count--; if (s.count < 0) { /* place this process in s.queue */; /* block this process */; void semSignal (semaphore s) { s.count++; if (s.count<= 0) { /* remove a process P from s.queue */; /* place process P on ready list */;
