Subject: Make parse_tree traversal a little bit easier
X-Git-Url: https://git.ljiriste.work/?a=commitdiff_plain;h=62f583c8ab43754b5265c708243f3f5353ebfa1e;p=Libft.git

Make parse_tree traversal a little bit easier

The ft_get_node_child function is very simple but may save a lot of
code, because ft_vec_access returns void* which needs to be cast before
further actions can be done.
(And casting to (t_parse_tree_node *) is a lot of code).
