Description
Creates a new list by applying the function f to the content of each element of lst. In case of problems creating an element, deletes the new list by using the function del.
Implementation
t_list *ft_lstmap(t_list *lst, void *(*f)(void *), void (*del)(void *))
{
t_list *ptr;
t_list *new_list;
t_list *new_element;
ptr = lst;
new_list = NULL;
while (ptr)
{
new_element = ft_lstnew((*f)(ptr->content));
if (!new_element)
{
ft_lstclear(&new_list, del);
return (NULL);
}
ft_lstadd_back(&new_list, new_element);
ptr = ptr->next;
}
return (new_list);
}
