# NAME¶

applyBdd - applies an operator to a list of BDD.

# SYNOPSYS¶

```#include "logmmm.h"
pNode applyBdd(oper,pt)
short oper;
chain_list *pt;
```

# PARAMETERS¶

oper
operator number to apply (OR,AND,XOR,NAND,NOR,NXOR,NOT)
pt
chain_list of BDD.

# DESCRIPTION¶

applyBdd() applies oper to a list of Bdd. This list can be created by addListBdd() function. This function provides the basic method for creating the representation of a function according to the operators in a boolean expression.

# EXAMPLE¶

```#include "mutnnn.h"		/* mbk utilities */
#include "logmmm.h"
pNode nodeA,nodeB,nodeC;
pNode res;
chain_list *pt;
initializeBdd(SMALL_BDD);
nodeA = createNodeTermBdd(3);
nodeB = createNodeTermBdd(3);
nodeC = createNodeTermBdd(4);
pt = NULL;
res = applyBdd(OR,pt);
displayBdd(res,1);
/* it will display
@res    INDEX = 4   LOW = @inter   HIGH = ONE
@inter  INDEX = 3   LOW = @nodeA   HIGH = ONE
@nodeA  INDEX = 2   LOW = ZERO	   HIGH = ONE
*/

destroyBdd(1);
```

# ERRORS¶

"applyBdd : error - unknown operator"
the operator number must be in (OR,AND,XOR,NAND,NOR,NXOR,NOT)
"applyBdd : error - chained list is empty"
chained list pointer pt = NULL.
"applyBdd : error - bad operator"
The number of arguments is 1 and the operator is distinct from NOT.
chained list pointer pt = NULL.
