bddnode *getbddvarnodebyindex( BddSystem, Index )
  bddsystem *BddSystem;
  bddindex   Index;

PARAMETERS

Index: The bdd index.

EXAMPLE

#include "bdd101.h"
   bddsystem  *BddSystem;
   bddnode    *BddNode;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   addbddvar( (bddsystem *)0, 0 );
   BddNode = getbddvarnodebyindex( (bddsystem *)0, 2 );
   ...
   destroybddsystem( (bddsystem *)0 );
