The following snippet of pseudo code for the producer consumer problem using semaphores has a logical error.

(Hint: you can assume that all down and up calls would be successful and not return an error code). semaphore m(1) // initialize counter to 1 semaphore s(0); // initialize counter to 0 Producer ============= sem_wait(&m) while (buffer full) {     sem_post(&m);     sem_wait(&s); }  // insert item into the buffer sem_post(&s); sem_post(&m);   Consumer ==============    sem_wait(&m); while (buffer empty) {      sem_post(&m);      sem_wait(&s); } // remove an item from the buffer sem_post(&s); sem_post(&m);
