## SYNOPSIS

**#include \<ck\_array.h\>**

*bool*\

**CK\_ARRAY\_FOREACH**(*ck\_array\_t \*array*, *ck\_array\_iterator\_t \*iterator*, *void \*\*b*);

## DESCRIPTION

The **CK\_ARRAY\_FOREACH**(*3*) macro iterates through the array pointed to by *array*. A pointer to an iterator object must be specified by *iterator* and *b* must point to a void pointer.

## EXAMPLE

```
#include <ck_array.h>
/* Assume this was already previously initialized. */
ck_array_t array;
void
example(void)
{
	ck_array_iterator_t iterator;
	void *pointer;
	CK_ARRAY_FOREACH(&array, &iterator, &pointer) {
		do_something(pointer);
	}
}
```
