#include "bdd101.h"
bddnode *addbddvarafter( BddSystem )
  bddsystem *BddSystem;
  bddindex      Index;

PARAMETERS

BddSystem: The bdd system.
Index: The bdd index of an existing variable.

DESCRIPTION

addbddvarafter creates a new variable, with the number BddSystem->INDEX_TO_VAR[ Index ] + 1 in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

RETURN VALUE

addbddvarafter returns a pointer to the bdd node of the new variable.

ERRORS

"no more variables, error !"

: There is no variable number left.

"index xxx out of range, error !"

: The Index parameter must be a valid index.

EXAMPLE

#include "bdd101.h"
   bddsystem  *BddSystem;
   bddnode    *BddNode1;
   bddnode    *BddNode2;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddNode1 = addbddvarfirst( (bddsystem *)0 );
   BddNode2 = addbddvarafter( (bddsystem *)0, BddNode1->INDEX );
   destroybddsystem( (bddsystem *)0 );
