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.
ERRORS

#include "bdd101.h"

bddcircuit *BddCircuit;
bddnode *BddNode;
bddnode *BddSubst;

bddassoc *Assoc;
chain_list *Expr;
bddvar Variable;
