  bddindex   Index;

PARAMETERS

BddSystem
The bdd system.
Index
The bdd index.

DESCRIPTION

getbddvarnode gives the bdd node of the bdd index Index, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The function uses simply the table BddSystem->VAR_NODE.

RETURN VALUE

getbddvarnode returns a pointer to the variable bdd node.

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 );
   addbddvar( (bddsystem ∗)0, 0 );
   BddNode = getbddvarnodebyindex( (bddsystem ∗)0, 2 );
   ...
   destroybddsystem( (bddsystem ∗)0 );
