The bdd system.
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 );
