BddSystem

The bdd system.

BddNode

The bdd node to unmark.

Mark

The bit mask.

unmarkbddnode unmarks the bdd node BddNode with the bit mask Mark, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. This function does a AND with the field MARK of the bdd node BddNode, and the complemented bit mask Mark.

unmarkbddnode returns the number of the different unmarked nodes.
