NAME

setbddrefext - increments the external reference, and decrements the internal reference of a bdd node.

See the file man1/alc_origin.1.

SYNOPSIS

#include "bdd101.h"
bddnode ∗setbddrefext( BddNode )


  bddnode ∗BddNode;

PARAMETERS

BddNode

The bdd node.

DESCRIPTION

setbddrefext increments the number of external reference of the bdd node BddNode and decrements its number of internal reference.

RETURN VALUE

setbddrefext returns the BddNode pointer.

ERRORS

"negative reference, index xxx error !"

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 );


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


   BddNode = addbddnode( (bddsystem ∗)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH );


   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );


   incbddrefint( BddNode );


   setbddrefext( BddNode );


   /* displays Node VAR: 0  INDEX: 2  MARK: 0  REF_EXT: 1  REF_INT: 0 */


   viewbddnode( (bddsystem ∗)0, BddNode );


   /* displays (not i0) */


   viewablexpr( Expr, ABL_VIEW_VHDL );


   freeablexpr( Expr );


   destroybddsystem( (bddsystem ∗)0 );


   destroybddcircuit( (bddcircuit ∗)0 );
