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 );
