Examples

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddnode    ∗BddNode;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddNode = addbddvar( (bddsystem ∗)0, 0 );
   /* displays 0 */
   printf( "%d", getbddvarbyindex( (bddsystem ∗)0, BddNode->INDEX ) );
   destroybddsystem( (bddsystem ∗)0 );
