int isbddvarinsupport( BddSystem, BddNode, Variable )
  bddsystem ∗BddSystem;
  bddnode   ∗BddNode;
  bddvar     Variable;

BddSystem

The bdd system.

BddNode

The bdd node.

Variable

The variable number.

isbddvarinsupport tests if the variable number Variable appears in the support of the bdd node BddNode, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

isbddvarinsupport returns 1 if Variable appears, 0 otherwise.

"variable xxx out of range, error !"
