NAME

6       existbddnodeassocon - computes an existential quantification.
7

SYNOPSIS

9       #include "bdd101.h"
10       bddnode ∗existbddnodeassocon( BddSystem, BddNode, BddAssoc )
11         bddsystem ∗BddSystem;
12         bddnode   ∗BddNode;
13         bddassoc  ∗BddAssoc;
14

PARAMETERS

16       BddSystem           The bdd system.
17
18       BddNode             The bdd node to treat.
19
20       BddAssoc            The variable association.
21

DESCRIPTION

23       existbddnodeassocon  suppress  in BddNode, all the variables associated
24       with something in the variable association BddAssoc, in the bdd  system
25       BddSystem.  If a null pointer is given, the default bdd system is used.
26

RETURN VALUE

28       existbddnodeassocon returns the computed bdd node.
29

ERRORS

31       "bad variable association xxx, error !"
32              The BddAssoc parameter must a valid variable association.
33
