# searchbddcircuitin(3)

searchs an input in a bdd circuit.

## NAME

searchbddcircuitin - searchs an input in a **bdd** circuit.

## SYNOPSYS

```
#include "bdd101.h"
  bddnode ∗searchbddcircuitin( BddCircuit, InputName )
  bddcircuit ∗BddCircuit;
  char       ∗InputName;
```

## PARAMETERS

- *BddCircuit*

  The **bdd** circuit.

- *InputName*

  The name of the input to look for.

## DESCRIPTION

**searchbddcircuitin** searchs the input *InputName* in the **bdd** circuit *BddCircuit*. If a null pointer is given, the default **bdd** circuit is used.\

## RETURN VALUE

**searchbddcircuitin** returns the node corresponding to the input *InputName* or a null pointer if no such input is found.

## EXAMPLE

```
#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddcircuit ∗BddCircuit;
   bddnode    ∗BddNode;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
   addbddcircuitin ( (bddcircuit ∗)0, "i0", 0, BDD_IN_MODE_FIRST );
   ...
   BddNode = searchbddcircuitin( (bddcircuit ∗)0, "i0" );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
```
