list_for_each_entry(pos, head, member):遍历链表中的每个结构体实例。 list_for_each_entry_safe ( pos, n, head, member):安全地遍历链表中的每个结构体实例,可以在遍历过程中安全地删除节点。 list_for_each_prev(pos, head):逆向遍历链表中的每个节点。 list_for_each_entry_reverse(pos, head, memb...
综上所述,我们可以了解到list_for_each_entry的作用:所有包含list_head的数据结构,均可使用此方法遍历链表;list_head结构体不包含数据部分,使用该函数进行遍历链表节点,然后在循环体中,对链表的数据部分进行读写操作,这就是list_for_each_entry的共通性 通过对链表中list成员的遍历,即可定位到链表的相关节点,进而...
某些应用需要反向遍历链表,Linux提供了list_for_each_prev()和list_for_each_entry_reverse()来完成这一操作,使用方法和上面介绍的list_for_each()、list_for_each_entry()完全相同。 如果遍历不是从链表头开始,而是从已知的某个节点pos开始,则可以使用list_for_each_entry_continue(pos,head,member)。有时还会...
n = list_entry(pos->member.next, typeof(*pos), member); \ &pos->member != (head); \ pos = n, n = list_entry(n->member.next, typeof(*n), member)) 3.9.2. 作用 list_for_each_entry的可删除结点版本。 3.10. list_for_each_entry_reverse 3.10.1. 定义 #definelist_for_each_en...
2、如果链表节点的内存是动态申请的,在遍历链表的循环中,取得链表数据后要释放节点资源,必须使用list_for_each_entry_safe,不能使用list_for_each_entry 否则将有访问异常风险,原因是:_safe才会将下一个节点先保存起来,当取得链表数据,释放完节点资源后,才能保证能查找到该节点后面的节点。
