warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

printf("consumer %d read from pool\n", (int)arg);
printf("producer %d write to pool\n", (int)arg);
//创建生产者线程pthread_create(&producer_id[i], NULL, producer_fun, (void *)i);//创建消费者线程pthread_create(&consumer_id[i], NULL, consumer_fun, (void *)i);

在生产者消费者问题中发现错误，最后发现原因是系统由于长度问题不支持这么转换，但是可以这么解决：

(int)arg = *(int *)arg
（void *)i = &i

printf("consumer %d read from pool\n", *(int *)argarg);
printf("producer %d write to pool\n", *(int *)argarg);
//创建生产者线程pthread_create(&producer_id[i], NULL, producer_fun, &i);//创建消费者线程pthread_create(&consumer_id[i], NULL, consumer_fun, &i);
