       Paris, France.

       Web : http://asim.lip6.fr/recherche/alliance/
       E-mail : alliance-users@asim.lip6.fr

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 );
