SCIPrbtreeDelete_call()

void SCIPrbtreeDelete_call	(	SCIP_RBTREENODE **	root,
		SCIP_RBTREENODE *	node
	)

delete the given node from the tree given by it's root node. The node must be contained in the tree rooted at root.

Parameters

root	root of the tree
node	node to delete from tree

void SCIPrbtreeInsert_call	(	SCIP_RBTREENODE **	root,
		SCIP_RBTREENODE *	parent,
		int	pos,
		SCIP_RBTREENODE *	node
	)

insert node into the tree given by it's root. Requires the future parent and the position of the parent as returned by the tree's find function defined using the SCIP_DEF_RBTREE_FIND macro.

Parameters

root	root of the tree
parent	future parent of node to be inserted
pos	position of parent with respect to node, i.e. -1 if the parent's key comes before node and 1 if the parent's key comes after the node
node	node to insert into the tree
