linux kernel list提供了2个添加链表项的API,分别是在链表的头部添加一个链表项和在链表的尾部添加一个列表项。因为linux kernel list定义链表结构的时候只定义了前向和后继两个指针,添加链表项也只是指针指向的变动;又因为从开始设计linux kernel list的时候就设定链表头是肯定存在的,所以也没有了链表是否为空之类...

linux kernel中的list估计已经被各位前辈们写烂了,但是我还是想在这里记录一下; linux kernel里的很多数据结构都很经典, list链表就是其中之一本篇要介绍的内容: list...的定义 list提供的操作方法注意事项使用实例 --- List 所在文件: List的所有操作可以在 i...
在Linux内核中,对于数据的管理,提供了2种类型的双向链表:一种是使用list_head结构体构成的环形双向链表;另一种是使用hlist_head和hlist_node2个结构体构成的具有表头的链型双向链表。 list_head的结构体如下所示: 代码语言:javascript 复制 struct list_head{struct list_head*next,*prev;}; ...
