getbddnodenum(3)

NAME

getbddnodenum - gets the number of nodes in a bdd.

SYNOPSYS

#include "bdd101.h"
long getbddnodenum( BddSystem, BddNode )
  bddsystem ∗BddSystem;
  bddnode   ∗BddNode;

PARAMETERS

BddSystem: The bdd system.

BddNode: The bdd node.

DESCRIPTION

getbddnodenum computes the number of different nodes in BddNode, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

RETURN VALUE

getbddnodenum returns the number of the different nodes reached.

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 );
   Expr = createablbinexpr( ABL_AND,
                            createablatom( "i0" ),
                            createablatom( "i1" ) );
   BddNode = addbddcircuitabl( BddCircuit, Expr );
   freeablexpr( Expr );
   printf( "Number nodes: %ld0,
           getbddnodenum( (bddsystem ∗)0, BddNode ) );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
