ewoc--node-nth

ewoc--node-nth is a compiled Lisp function in `ewoc.el'.

(ewoc--node-nth DLL N)

Return the Nth node from the doubly linked list `dll'.
N counts from zero. If N is negative, return the -(N+1)th last element.
If N is out of range, return nil.
Thus, (ewoc--node-nth dll 0) returns the first node,
and (ewoc--node-nth dll -1) returns the last node.
