NAME

       getbddvarnode - gives the bdd node of a variable.

SYNOPSYS

       #include "bdd101.h"
       bddnode ∗getbddvarnode( BddSystem, Variable )
         bddsystem ∗BddSystem;
         bddvar     Variable;

PARAMETERS

       BddSystem           The bdd system.

       Variable            The variable number.

DESCRIPTION

       getbddvarnode  gives  the  bdd  node  of  the  variable number Variable, in the bdd system
       BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       getbddvarnode returns a pointer to the variable bdd node.

ERRORS

       "variable xxx out of range, error !"
              The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.

EXAMPLE

       #include "bdd101.h"
          bddsystem  ∗BddSystem;
          bddnode    ∗BddNode;
          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
          addbddvar( (bddsystem ∗)0, 0 );
          BddNode = getbddvarnode( (bddsystem ∗)0, 0 );
          ...
          destroybddsystem( (bddsystem ∗)0 );
