The fоllоwing snippet оf pseudo code for the producer consumer problem using semаphores hаs а logical error. Identify the location of the error, explain what can go wrong, and suggest a fix to eliminate the error. (Hint: you can assume that all wait and post 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);
