SYNOPSYS

#include "bdd101.h"
void swapbddvar( BddSystem, Variable )
  bddsystem ∗BddSystem;
  bddvar     Variable;

PARAMETERS

BddSystem
The bdd system.
Variable
The variable to swap.

DESCRIPTION

swapbddvar swaps the variable number Variable with the variable number Variable + 1, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. This function is usefull for the bdd nodes reordering.

RETURN VALUE

swapbddvar returns nothing.

ERRORS

"variable xxx out of range, error !"
The Variable and Variable + 1, must be valid variables number.

EXAMPLE

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddnode    ∗BddNode1;
   bddnode    ∗BddNode2;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddNode1 = addbddvar( (bddsystem ∗)0, 0 );
   BddNode2 = addbddvar( (bddsystem ∗)0, 0 );
   swapbddvar( (bddsystem ∗)0, 0 );
   destroybddsystem( (bddsystem ∗)0 );
