)- Description
Traverse the node subtree in preorder, root node first, then subtrees from left to right. For each node we call
cb_1
before iterating through children, and thencb_2
(which always gets called even if the walk is aborted earlier). If the callback function returns STOP_WALK the traverse decend is aborted and STOP_WALK is returned once all waitingcb_2
functions have been called.
