Llana [10]

Answer:

// Producer Thread

void *producer(void *param) {

buffer_item item;

while (true) {

item = rand() % 100;

sem_wait(&empty);

pthread_mutex_lock(&mutex);

if (insert_item(item))

printf("Can't insert item\n");

else

printf("Producer %d: produced %d\n", *((int*)param), item);

pthread_mutex_unlock(&mutex);

sem_post(&full);

}

// Consumer Thread

void *consumer(void *param) {

while (true) {

buffer_item item = NULL;

if (in > 0)

item = buffer[in - 1];

sem_wait(&full);

pthread_mutex_lock(&mutex);

if (remove_item(&item))

printf("Can't remove item\n");

else

printf("Consumer %d: consumed %d\n", *((int*)param), item);

pthread_mutex_unlock(&mutex);

sem_post(&empty);

}
