# applybddnodenot(3)

complements a bdd.

## NAME

applybddnodenot - complements a **bdd**.

## SYNOPSYS

```
#include "bdd101.h"
bddnode ∗applybddnodenot( BddSystem, BddNode )
  bddsystem ∗BddSystem;
  bddnode   ∗BddNode;
```

## PARAMETERS

- *BddSystem*

  The **bdd** system.

- *BddNode*

  The **bdd** node to complement.

## DESCRIPTION

**applybddnodenot** complements *BddNode* in the **bdd** system *BddSystem*. If a null pointer is given, the default **bdd** system is used.\

## RETURN VALUE

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

## 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,
                           ABL_AND,
                           searchbddcircuitin( (bddcircuit ∗)0, "i0" ),
                           searchbddcircuitin( (bddcircuit ∗)0, "i1" ) );
   BddNode = applybddnodenot( (bddsystem ∗)0, decbddrefext( BddNode ) );
   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
   /* displays (i0 nand i1) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
```
