DECBDDREFEXT(3) 						   BDD FUNCTIONS						   DECBDDREFEXT(3)

NAME
       decbddrefext - decrements the external reference of a bdd node.

ORIGIN
       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

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

PARAMETERS
       BddNode		   The bdd node.

DESCRIPTION
       decbddrefext decrements the number of external reference of the bdd node BddNode.

RETURN VALUE
       decbddrefext returns the BddNode pointer.

ERRORS
       "negative reference, index xxx error !"
	      The BddNode must have a postive number of external reference.

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