Detailed Description

wl_list - linked list

The list head is of "struct wl_list" type, and must be initialized using wl_list_init(). All entries in the list must be of the same type. The item type must have a "struct wl_list" member. This member will be initialized by wl_list_insert(). There is no need to call wl_list_init() on the individual item. To query if the list is empty in O(1), use wl_list_empty().

Let's call the list reference "struct wl_list foo_list", the item type as "item_t", and the item member as "struct wl_list link". The following code

The following code will initialize a list:

wl_list_init(foo_list); wl_list_insert(foo_list, item1); Pushes item1 at the head wl_list_insert(foo_list, item2); Pushes item2 at the head wl_list_insert(item2, item3); Pushes item3 after item2

The list now looks like [item2, item3, item1]

Will iterate the list in ascending order:

item_t *item; wl_list_for_each(item, foo_list, link) { Do_something_with_item(item); }
