relprodbddnodeassoc(3) - Linux man page

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.
