UNSETBDDREFEXT(3)						   BDD FUNCTIONS						 UNSETBDDREFEXT(3)

NAME
       unsetbddrefext - increments the internal reference, and 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 *unsetbddrefext( BddNode )
	 bddnode *BddNode;

PARAMETERS
       BddNode		   The bdd node.

DESCRIPTION
       unsetbddrefext increments the number of internal reference of the bdd node BddNode and decrements its number of external reference.

RETURN VALUE
       unsetbddrefext 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 );
	  incbddrefext( BddNode );
	  unsetbddrefext( BddNode );
	  /* displays Node VAR: 0  INDEX: 2  MARK: 0  REF_EXT: 0  REF_INT: 1 */
	  viewbddnode( (bddsystem *)0, BddNode );
	  /* displays (not i0) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
