# applybddnodeite(3)

computes the IF-THEN-ELSE logical operation.

## NAME

applybddnodeite - computes the IF-THEN-ELSE logical operation.

## SYNOPSYS

```
#include "bdd101.h"
bddnode ∗applybddnodeite( BddSystem, BddIf, BddThen, BddElse )
  bddnode   ∗BddSystem;
  bddnode   ∗BddIf;
  bddnode   ∗BddThen;
  bddnode   ∗BddElse;
```

## PARAMETERS

- *BddSystem*

  The **bdd** system.

- *BddIf*

  The IF **bdd** node.

- *BddThen*

  The THEN **bdd** node.

- *BddElse*

  The ELSE **bdd** node.

## DESCRIPTION

**applybddnodeite** computes the following logical function (*BddIf* AND *BddThen*) OR ((NOT *BddIf*) AND *BddElse*) in the **bdd** system *BddSystem*. If a null pointer is given, the default **bdd** system is used.\

## RETURN VALUE

**applybddnodeite** 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 );
   addbddcircuitin( (bddcircuit ∗)0, "i2", 0, BDD_IN_MODE_FIRST );
   BddNode = applybddnodeite( (bddsystem ∗)0,
                              searchbddcircuitin( (bddcircuit ∗)0, "i0" ),
                              searchbddcircuitin( (bddcircuit ∗)0, "i1" ),
                              searchbddcircuitin( (bddcircuit ∗)0, "i2" ) );
   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
   /* displays ((i0 and i1) or ((not i0) and i2) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
```
