NAME

applybddnode - applies an operator on two bdd nodes.

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

SYNOPSYS

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


  bddsystem ∗BddSystem;


  long       Oper;


  bddnode   ∗BddNode1;


  bddnode   ∗BddNode2;

PARAMETERS

BddSystem: The bdd system.
Oper: The binary operator.
BddNode1: The first bdd node.
BddNode2: The second bdd node.

DESCRIPTION

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 !"

The Oper parameter must be a valid binary operator.

EXAMPLE

#include "bdd101.h"


   bddsystem  ∗BddSystem;


   bddcircuit ∗BddCircuit;


   bddnode    ∗BddNode;


   chain_list ∗Expr;


   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );


   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );


   addbddcircuitin( (bddcircuit ∗)0, "i0", 0, BDD_IN_MODE_FIRST );


   addbddcircuitin( (bddcircuit ∗)0, "i1", 0, BDD_IN_MODE_FIRST );


   BddNode = applybddnode( (bddsystem ∗)0,
