NAME

       getbddvarbyindex - converts bdd index to a variable number.

SYNOPSYS

       #include "bdd101.h"
       bddindex getbddvarbyindex( BddSystem, Index )
         bddsystem ∗BddSystem;
         bddindex   Index;

PARAMETERS

       BddSystem           The bdd system.

       Index               The bdd index to convert.

DESCRIPTION

       getbddvarbyindex  converts  the bdd index  Index to a variable number, in the bdd system BddSystem.  If a
       null pointer is given, the default bdd system is used.  The function uses simply  the  translation  table
       BddSystem->INDEX_TO_VAR.

RETURN VALUE

       getbddvarbyindex returns the variable number of the bdd index Index.

ERRORS

       "index xxx out of range, error !"
              The Index parameter must be a valid index.

EXAMPLE

       #include "bdd101.h"
          bddsystem  ∗BddSystem;
          bddnode    ∗BddNode;
          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
          BddNode = addbddvar( (bddsystem ∗)0, 0 );
          /* displays 0 */
          printf( "%d", getbddvarbyindex( (bddsystem ∗)0, BddNode->INDEX ) );
          destroybddsystem( (bddsystem ∗)0 );
