NAME

       getbddvarindex - converts a variable number in a bdd index.

SYNOPSYS

       #include "bdd101.h"
       bddindex getbddvarindex( BddSystem, Variable )
         bddsystem ∗BddSystem;
         bddvar     Variable;

PARAMETERS

       BddSystem           The bdd system.

       Variable            The variable number to convert.

DESCRIPTION

       getbddvarindex  converts  the  variable  number Variable to a bdd index, 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->VAR_TO_INDEX.

RETURN VALUE

       getbddvarindex returns the bdd index of Variable.

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 );
          BddNode = addbddvar( (bddsystem ∗)0, 0 );
          /* displays 2 */
          printf( "%d", getbddvarindex( (bddsystem ∗)0, 0 ) );
          destroybddsystem( (bddsystem ∗)0 );
