applybddnode3

Synopsys

#include "bdd101.h"
bddnode ∗applybddnode( BddSystem, Oper, BddNode1, BddNode2 )
  bddsystem ∗BddSystem;
  long       Oper;
  bddnode   ∗BddNode1;
  bddnode   ∗BddNode2;

Parameters

Overview

applybddnode computes the boolean function BddNode1 Oper BddNode2 in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

Return value

applybddnode returns a pointer to the resulting bdd node with its number of external reference incremented.

Errors

"bad operator xxx error !"
