NAME

       relprodbddnodeassoc - computes a relational product.

SYNOPSYS

       #include "bdd101.h"
       bddnode ∗relprodbddnodeassoc( BddSystem, BddNode1, BddNode2, BddAssoc )
         bddsystem ∗BddSystem;
         bddnode   ∗BddNode1;
         bddnode   ∗BddNode2;
         bddassoc  ∗BddAssoc;

PARAMETERS

       BddSystem           The bdd system.

       BddNode1            The first bdd node.

       BddNode2            The second bdd node.

       BddAssoc            The variable association.

DESCRIPTION

       relprodbddnodeassoc  computes BddNode1 AND BddNode2, and suppress the variables associated
       with something in the variable association BddAssoc, in the bdd system  BddSystem.   If  a
       null pointer is given, the default bdd system is used.

RETURN VALUE

       relprodbddnodeassoc returns the computed bdd node.

ERRORS

       "bad variable association xxx, error !"
              The BddAssoc parameter must a valid variable association.
