NAME

       incbddrefint - increments the internal reference of a bdd node.

SYNOPSYS

       #include "bdd101.h"
       bddnode ∗incbddrefint( BddNode )
         bddnode ∗BddNode;

PARAMETERS

       BddNode             The bdd node.

DESCRIPTION

       incbddrefint increments the number of internal reference of the bdd node BddNode.

RETURN VALUE

       incbddrefint returns the BddNode pointer.

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 );
          /* displays Node VAR: 0  INDEX: 2  MARK: 0  REF_EXT: 1  REF_INT: 1 */
          viewbddnode( (bddsystem ∗)0, BddNode );
          /* displays (not i0) */
          viewablexpr( Expr, ABL_VIEW_VHDL );
          freeablexpr( Expr );
          destroybddsystem( (bddsystem ∗)0 );
          destroybddcircuit( (bddcircuit ∗)0 );
