INCBDDREFEXT(3)			 BDD FUNCTIONS		       INCBDDREFEXT(3)

NAME
       incbddrefext - increments the external reference	of a bdd node.

SYNOPSYS
       #include	"bdd101.h"
       bddnode *incbddrefext( BddNode )
	 bddnode *BddNode;

PARAMETERS
       BddNode		   The bdd node.

DESCRIPTION
       incbddrefext  increments	 the  number  of external reference of the bdd
       node BddNode.

RETURN VALUE
       incbddrefext returns the	BddNode	pointer.

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	);
	  incbddrefext(	BddNode	);
	  /* displays Node VAR:	0  INDEX: 2  MARK: 0  REF_EXT: 2  REF_INT: 0 */
	  viewbddnode( (bddsystem *)0, BddNode );
	  /* displays (not i0) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
