See the file buster/alliance/alc_origin.1.en.gz.

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 );
