ADDBDDNODE(3)			 BDD FUNCTIONS			 ADDBDDNODE(3)

NAME
       addbddnode - adds a new bdd node	in the bdd system.

SYNOPSYS
       #include	"bdd101.h"
       bddnode *addbddnode( BddSystem, Index, High, Low	 )
	 bddsystem *BddSystem;
	 bddindex   Index;
	 bddnode   *High;
	 bddnode   *Low;

PARAMETERS
       BddSystem	   The bdd system.

       Index		   The bdd index.

       High		   The bdd high	pointer.

       Low		   The bdd low pointer.

DESCRIPTION
       addbddnode  adds	a new node with	the index Index, High as HIGH pointer,
       and Low as LOW pointer in the bdd system	BddSystem. If the bdd node ex-
       ist already addbddnode return its pointer.  If a	null pointer is	given,
       the default bdd system is used.

RETURN VALUE
       addbddnode returns a pointer to the resulting bdd node with its	number
       of external reference incremented.

ERRORS
       "index xxx out of range"
	      The Index	parameter must be a valid index.

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	);
	  /* displays (not i0) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
