unmarkbddnode(3)

NAME

unmarkbddnode - unmarks bdd node with a specified mask.

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 );
