# delbddnodelist(3)

deletes a list of bdd nodes.

## NAME

delbddnodelist - deletes a list of **bdd** nodes.

## SYNOPSYS

```
#include "bdd101.h"
void delbddnodelist( BddSystem, HeadList )
  bddsystem  ∗BddSystem;
  chain_list ∗HeadList;
```

## PARAMETERS

- *BddSystem*

  The **bdd** system.

- *HeadList*

  The head of the *chain\_list*.

## DESCRIPTION

**delbddnodelist** deletes all the **bdd** nodes of the list *HeadList* in the **bdd** system *BddSystem*. If a null pointer is given, the default **bdd** system is used. All the nodes have their external references decremented.\

## RETURN VALUE

**delbddnodelist** returns nothing.

## EXAMPLE

```
#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddcircuit ∗BddCircuit;
   bddnode    ∗BddNode;
   chain_list ∗BddList;
   chain_list ∗Expr;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
   BddList    = (chain_list ∗)0;
   BddList = addbddnodelist( (bddsystem ∗)0, BddList,
                             addbddcircuitin( (bddcircuit ∗)0,
                                              "i0", 0, BDD_IN_MODE_FIRST ) );
   BddList = addbddnodelist( (bddsystem ∗)0, BddList,
                              addbddcircuitin( (bddcircuit ∗)0,
                                               "i1", 0, BDD_IN_MODE_FIRST );
   BddList = addbddnodelist( (bddsystem ∗)0, BddList,
                             addbddcircuitin( (bddcircuit ∗)0,
                                              "i2", 0, BDD_IN_MODE_FIRST );
   BddNode = applybddnodelist( (bddsystem ∗)0, ABL_AND, BddList );
   delbddnodelist( (bddsystem ∗)0, BddList );
   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
   /* displays (i0 and i1 and i2) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
