NAME

       delbddnode - deletes an unused bdd node.

SYNOPSYS

       #include "bdd101.h"
       void delbddnode( BddSystem, BddNode )
         bddsystem ∗BddSystem;
         bddnode   ∗BddNode;

PARAMETERS

       BddSystem           The bdd system.

       BddNode             The bdd node.

DESCRIPTION

       delbddnode tries to delete the bdd node BddNode and its children, if they have not external reference, in
       the bdd system BddSystem.  If a null pointer is given, the default bdd system is used. The  use  of  this
       function  is not recommended because, it takes time.  It is better to call the decbddrefext function, and
       do a garbage collection with the garbagebddsystem function.

RETURN VALUE

       delbddnode 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 );
          BddNode = addbddcircuitin( (bddcircuit ∗)0, "i0", 0, BDD_IN_MODE_FIRST );
          BddNode = addbddnode( (bddsystem ∗)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH );
          Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
          delbddnode( (bddsystem ∗)0, decbddrefext( BddNode ) );
          /* displays (not i0) */
          viewablexpr( Expr, ABL_VIEW_VHDL );
          freeablexpr( Expr );
          destroybddsystem( (bddsystem ∗)0 );
          destroybddcircuit( (bddcircuit ∗)0 );
