NAME

       destroybddassoc - frees all the variable associations.

SYNOPSYS

       #include "bdd101.h"
       bddassoc ∗destroybddassoc( BddSystem )
         bddsystem  ∗BddSystem;

PARAMETERS

       BddSystem           The bdd system.

DESCRIPTION

       destroybddassoc  frees  all  the  variable associations in the bdd system BddSystem.  If a
       null pointer is given, the default bdd system is used.

RETURN VALUE

       destroybddassoc returns nothing.
