APPLYBDDNODEITE(3)		 BDD FUNCTIONS		    APPLYBDDNODEITE(3)

NAME
       applybddnodeite - computes the IF-THEN-ELSE logical operation.

SYNOPSYS
       #include	"bdd101.h"
       bddnode *applybddnodeite( BddSystem, BddIf, BddThen, BddElse )
	 bddnode   *BddSystem;
	 bddnode   *BddIf;
	 bddnode   *BddThen;
	 bddnode   *BddElse;

PARAMETERS
       BddSystem	   The bdd system.

       BddIf		   The IF bdd node.

       BddThen		   The THEN bdd	node.

       BddElse		   The ELSE bdd	node.

DESCRIPTION
       applybddnodeite	computes the following logical function	(BddIf AND Bd-
       dThen) OR ((NOT BddIf) AND BddElse) in the bdd system BddSystem.	 If  a
       null pointer is given, the default bdd system is	used.

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

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 );
	  addbddcircuitin( (bddcircuit *)0, "i0", 0, BDD_IN_MODE_FIRST );
	  addbddcircuitin( (bddcircuit *)0, "i1", 0, BDD_IN_MODE_FIRST );
	  addbddcircuitin( (bddcircuit *)0, "i2", 0, BDD_IN_MODE_FIRST );
	  BddNode = applybddnodeite( (bddsystem	*)0,
				     searchbddcircuitin( (bddcircuit *)0, "i0" ),
				     searchbddcircuitin( (bddcircuit *)0, "i1" ),
				     searchbddcircuitin( (bddcircuit *)0, "i2" ) );
	  Expr = convertbddcircuitabl( (bddcircuit *)0,	BddNode	);
	  /* displays ((i0 and i1) or ((not i0)	and i2)	*/
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
