NAME

       getbddvarnode - gives the bdd node of a variable.

SYNOPSYS

       #include "bdd101.h"
       bddnode ∗getbddvarnodebyindex( BddSystem, Index )
         bddsystem ∗BddSystem;
         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 );
