addbddassoc.3alc - Man Page

creates a new association variables.

Synopsis

#include "bdd101.h"
bddassoc ∗addbddassoc( BddSystem )
  bddsystem  ∗BddSystem;

Parameters

BddSystem

The bdd system.

Description

addbddassoc creates a new association variables in the bdd system BddSystem.  If a null pointer is given, the default bdd system is used.

Return Value

addbddassoc returns a pointer to the new variable association.

Errors

"no more variable association, error !"

There is no variable association number left.

   bddcircuit ∗BddCircuit;
   bddnode    ∗BddNode;
   bddnode    ∗BddSubst;
   bddnode    ∗BddVariable;
   bddassoc   ∗Assoc;
   chain_list ∗Expr;
   bddvar         Variable;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
