# addbddcircuitout(3)

adds an output in a bdd circuit.

## NAME

addbddcircuitout - adds an output in a **bdd** circuit.

## SYNOPSYS

```
#include "bdd101.h"
bddnode ∗addbddcircuitout( BddCircuit, OutputName, BddNode )
  bddcircuit ∗BddCircuit;
  char       ∗OutputName;
  bddnode    ∗BddNode;
```

## PARAMETERS

- *BddCircuit*

  The **bdd** circuit.

- *OutputName*

  The name of the output.

- *BddNode*

  The **bdd** node of the output.

## DESCRIPTION

**addbddcircuitout** adds *BddNode* as an output *OutputName* in the **bdd** circuit *BddCircuit*. If a null pointer is given, the default **bdd** circuit is used. If the output *OutputName* exists already, the number of external reference of the old node is decremented, and the output node is replaced by the new one.\

## RETURN VALUE

**addbddcircuitout** returns the node *BddNode* with its number of external  reference incremented.

## EXAMPLE

```
#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddcircuit ∗BddCircuit;
   bddnode    ∗BddNode;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
   ...
   addbddcircuitout( (bddcircuit ∗)0, "Out0", BddNode );
   ...
   BddNode = searchbddcircuitout( (bddcircuit ∗)0, "Out0" );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
```
