# markbddnode(3)

marks bdd node with a specified mask.

## NAME

markbddnode - marks **bdd** node with a specified mask.

## SYNOPSYS

```
#include "bdd101.h"
long markbddnode( BddSystem, BddNode, Mark )
  bddsystem ∗BddSystem;
  bddnode   ∗BddNode;
  bddmark    Mark;
```

## PARAMETERS

- *BddSystem*

  The **bdd** system.

- *BddNode*

  The **bdd** node to mark.

- *Mark*

  The bit mask.

## DESCRIPTION

**markbddnode** marks the **bdd** node *BddNode* with the bit mask *Mark*, in the **bdd** system BddSystem. If a null pointer is given, the default **bdd** system is used. This function does a OR with the field MARK of the **bdd** node *BddNode*, and the bit mask *Mark*.\

## RETURN VALUE

**markbddnode** returns the number of the differents marked nodes.

## 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 );
   Expr = createablbinexpr( ABL_AND,
                            createablatom( "i0" ),
                            createablatom( "i1" ) );
   BddNode = addbddcircuitabl( BddCircuit, Expr );
   freeablexpr( Expr );
   printf( "Number nodes: %ld0,
           markbddnode( (bddsystem ∗)0, BddNode, 0x0001 ) );
   unmarkbddnode( (bddsystem ∗)0, BddNode, 0x0001 );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
```
