UNMARKBDDNODE(3)						   BDD FUNCTIONS						  UNMARKBDDNODE(3)

NAME

       unmarkbddnode - unmarks bdd node with a specified mask.

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"
       long unmarkbddnode( BddSystem, BddNode, Mark )
	 bddsystem *BddSystem;
	 bddnode   *BddNode;
	 bddunmark    Mark;

PARAMETERS

       BddSystem	   The bdd system.

       BddNode		   The bdd node to unmark.

       Mark		   The bit mask.

DESCRIPTION

       unmarkbddnode unmarks the bdd node BddNode with the bit mask Mark, in the bdd system BddSystem.	If a null pointer is  given,  the  default
       bdd system is used.  This function does a AND with the field MARK of the bdd node BddNode, and the complemented bit mask Mark.

RETURN VALUE

       unmarkbddnode returns the number of the differents unmarked nodes.

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 );
	  Expr = createablbinexpr( ABL_AND,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  printf( "Number nodes: %ld0,
		  markbddnode( (bddsystem *)0, BddNode, 0x0001 ) );
	  unmarkbddnode( (bddsystem *)0, BddNode, 0x0001 );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
