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 );
