我在用c语言解决哲学家的就餐问题我使用的是pthread_create（）和更高版本的pthread_join当一个哲学家"死了"时，我需要立即停止程序，这样其他线程就不会继续执行操作，所以我使用exit（）。问题是valgrind告诉我没有释放应该从线程中释放的资源（我没有在它们里面使用任何动态内存）所以我猜是线程本身的创建没有释放，我试过使用pthread_detach，但是它也让我丢失了分配内存。我该怎么做才能在那个时候终止所有线程而不出现这个问题呢？
我在另一个函数中退出程序，该函数销毁了所有互斥锁，稍后使用exit（）
创建线程的代码如下所示：

while (++i < d->philo_n)
    {

        d->philos[i].n = i;
        d->philos[i].data = d;
        d->philos[i].eat_times = 0;
        d->philos[i].last_eat = -1;
        pthread_mutex_init(&(d->philos[i].l_fork), NULL);
        if (i == d->philo_n - 1)
            d->philos[i].r_fork = &(d->philos[0].l_fork);
        else
            d->philos[i].r_fork = &(d->philos[i + 1].l_fork);
        pthread_create(&(d->philos[i].thread), NULL, routine1, &(d->philos[i]));

    }
    i = -1;
    while (++i < d->philo_n)
        if (pthread_join(d->philos[i].thread, NULL) != 0)
            return ;

valgrind错误如下：
