Synopsis

#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.
