getbddvarbyindex(3) 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 );
