NAME
       isbddvarinsupport - tests if a variable appears in a bdd.

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"
       int isbddvarinsupport( BddSystem, BddNode, Variable )
	 bddsystem *BddSystem;
	 bddnode   *BddNode;
	 bddvar     Variable;

PARAMETERS
       BddSystem	   The bdd system.

       BddNode		   The bdd node.

       Variable 	   The variable number.

DESCRIPTION
       isbddvarinsupport tests if the variable number Variable appears in the support of the bdd node BddNode, in the bdd system BddSystem.  If  a
       null pointer is given, the default bdd system is used.

RETURN VALUE
       isbddvarinsupport returns 1 if Variable appears, 0 otherwise.

ERRORS
       "variable xxx out of range, error !"
	      The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.

EXAMPLE
       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddNode;
	  bddnode    *BddVariable;
	  chain_list *Expr;
	  bddvar	 Variable;
	  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 );
	  BddVariable = searchbddcircuitin( (bddcircuit *)0, "i0" );
	  Variable = getbddvarbyindex( (bddsystem * 0), BddVariable->INDEX ) );
	  /* displays 1 */
	  printf( "%d", isbddvarinsupport( (bddsystem *)0, BddNode, Variable ) );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
