SYNOPSYS

       #include "bdd101.h"
       bddnode *getbddvarnode( BddSystem, Variable )
	 bddsystem *BddSystem;
	 bddvar     Variable;

PARAMETERS

       BddSystem	   The bdd system.

       Variable 	   The variable number.

DESCRIPTION

       getbddvarnode gives the bdd node of the variable number Variable, in the bdd system BddSystem.  If a null pointer is given, the default bdd
       system is used.

RETURN VALUE

       getbddvarnode returns a pointer to the variable bdd node.

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;
	  bddnode    *BddNode;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  addbddvar( (bddsystem *)0, 0 );
	  BddNode = getbddvarnode( (bddsystem *)0, 0 );
	  ...
	  destroybddsystem( (bddsystem *)0 );
