Linux代码看的比较多了,经常会遇到container_of和list_for_each_entry,特别是 list_for_each_entry比较多,因为Linux经常用到链表,虽然知道这些函数的大概意思,但一旦出现一个类似的函数比如 list_for_each_entry_safe就又会感到头大,所以下定决心分析总结一下这些函数的用法,以后再看到这些面孔的时候也会轻松很多,...
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)。有时还会出现这种需求,即经过一系列计算后,如果pos有值,则从pos开始遍历,如果没有,则从链表头开始,为此,Linux专门提供了一个list_prepare_entry(pos,head,member)宏,将它的返回值作为list_for_e...
从定义可以看出,这两个宏只在for循环的第一个分号前存在不同,在list_for_each_entry_continue(pos, head, member)中,pos = list_entry(pos->member.next, typeof(*pos), member); 即指向了当前pos结构指针的后一个,说明遍历从pos的后一个元素开始;而在define list_for_each_entry_from(pos, head, memb...
#definelist_for_each_entry_safe(pos, n, head, member) \ for (pos = list_entry((head)->next, typeof(*pos), member), \ n = list_entry(pos->member.next, typeof(*pos), member); \ &pos->member != (head); \ pos = n, n = list_entry(n->member.next, typeof(*n), member...
testList.add(3); testList.forEach(val->{if(val == 2) {return; } System.out.println(val); }); 结果如下 foreach()中使用break 效果:不会退出当前循环,不起作用 foreach()中使用continue 效果:不会退出当前条件下的循环并执行下一次循环,不起作用...
