NAME

       getbddnodesupport - gives the variable support of a bdd node.

SYNOPSYS

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

PARAMETERS

       BddSystem           The bdd system.

       BddNode             The bdd node.

       Mode                The type of support.

DESCRIPTION

       getbddnodesupport  gives  the  support  of  the  bdd node BddNode in the bdd system BddSystem.  If a null
       pointer is given, the default bdd system is used.  If Mode is BDD_SUPPORT_CHAIN the support  is  returned
       using  chain_list else it is returned using ptype_list.  The support must be freed using the freechain or
       freeptype functions.

RETURN VALUE

       getablexprsupport returns a pointer to a chain_list or a ptype_list.

EXAMPLE

       #include "bdd101.h"
          bddsystem  ∗BddSystem;
          bddcircuit ∗BddCircuit;
          bddnode    ∗BddNode;
          chain_list ∗Expr;
          chain_list ∗Support;
          chain_list ∗ScanSupport;
          bddindex       Index;
          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
          BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
          Expr = createablbinexpr( ABL_AND,
                                   createablatom( "i0" ),
                                   createablatom( "i1" ) );
          BddNode = addbddcircuitabl( BddCircuit, Expr );
          freeablexpr( Expr );
          Support = getablbddnodesupport( (bddsystem ∗0), BddNode, BDD_SUPPORT_CHAIN );
          for ( ScanSupport  = Support;
                ScanSupport != (chain_list ∗)0;
                ScanSupport  = ScanSupport->NEXT )
          {
            Index = (bddnode ∗)ScanSupport->INDEX;
            printf( "%s ", BddCircuit->NAME_IN[ Index - BDD_INDEX_MIN ] );
          }
          freechain( Support );
          destroybddsystem( (bddsystem ∗)0 );
          destroybddcircuit( (bddcircuit ∗)0 );
