BddSystem

The bdd system.

BddNode1

The first bdd node.

BddNode2

The second bdd node.

intersectbddnode tests if the intersection of BddNode1 and BddNode2 exists, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

intersectbddnode returns the bdd node zero if there is no  intersection, and a computed bdd node otherwise.
