学习内核第一天

学习内核第一天，大致看了看linux内核里的双链表结构，并写了个简单的程序 #define __KERNEL__ #include <linux/list.h> struct mylist {
        struct list_head list;
        int index;
}; struct mylist top_conn; void
add_top_conn(struct mylist *list)
{
        list_add(&list->list, &top_conn.list);
} void
print_top_conn(void)
{
        struct list_head *ptr;
        struct mylist *conn;         for (ptr = top_conn.list.next; \
                ptr != &top_conn.list; ptr = ptr->next)
        {
                conn = list_entry(ptr, struct mylist, list);
                printf("index: %d \n", conn->index);
        }
} int
main(void)
{
        struct mylist a;
        struct mylist b;
        struct mylist c;
        a.index=1;
        b.index=2;
        c.index=4;         INIT_LIST_HEAD(&top_conn.list);
        add_top_conn(&a);
        add_top_conn(&b);
        add_top_conn(&c);
        print_top_conn();         return 1;
}
