SYNOPSYS

#include "bdd101.h"
void garbagebddsystem( BddSystem )
  bddsystem *BddSystem;

PARAMETERS

BddSystem

The bdd system.

DESCRIPTION

garbagebddsystem frees all the unused bdd nodes in the system BddSystem. If a null pointer is given, the default bdd system is used. A bdd node is unused if its number of reference is null.

RETURN VALUE

garbagebddsystem returns nothing.

EXAMPLE

#include "bdd101.h"
   bddsystem  *BddSystem;
   bddcircuit *BddCircuit;
   bddnode    *BddNode;
   chain_list *Expr;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
   addbddcircuitin( (bddcircuit *)0, "i0", 0, BDD_IN_MODE_FIRST );
   addbddcircuitin( (bddcircuit *)0, "i1", 0, BDD_IN_MODE_FIRST );
   BddNode = applybddnode( (bddsystem *)0,
                           ABL_AND,
                           searchbddcircuitin( (bddcircuit *)0, "i0" ),
                           searchbddcircuitin( (bddcircuit *)0, "i1" ) );
   decbddrefext( BddNode );
   garbagebddsystem( (bddsystem *)0 );
   destroybddsystem( (bddsystem *)0 );
   destroybddcircuit( (bddcircuit *)0 );
