NAME

destroybddassoc - frees all the variable associations.

See the file buster/alliance/alc_origin.1.en.gz.

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.
