struct list_head { struct list_head *next, *prev; } In the code supplied to your question: struct task list_head; 'struct task' contains a 'struct list_head' element. Then later: list_for_each() which is defined in 'list.h', which requires uses 'pos' and 'head' to iterate the list. WebDec 30, 2024 · struct mystruct first = { .data = 10, .mylist = LIST_HEAD_INIT (first.mylist) } ; The last line is calling a macro LIST_HEAD_INIT which is defined in /include/linux/list.h: 18 19 #define LIST_HEAD_INIT (name) { & (name), & (name) } 20. This macro is simply used to assign each pointer inside the mylist field to point to that very field thus ...
WebFeb 29, 2024 · 1 概述. 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_node 2个结构体构成的具有表头的链型双向链表。. struct hlist_head { struct hlist_node *first; }; struct … Web对于list_entry宏来说ptr在这里为指向children链表的指针,type为task_struct结构体的类型,member为链表成员的变量名,即children。 container_of()思路为先求出结构体成员member(即children)在结构体(即task_struct)中的偏移量,然后再根据member的地址(即ptr)来求出结构体(即task_struct ...

WebThe list_head structures are good for implementing a list of like structures, but the invoking program is usually more interested in the larger structures that make up the list as a whole. A macro, list_entry, is provided that will map a list_head structure pointer back into a pointer to the structure that contains it.
