Functions
hashset_itr_t	hashset_iterator (hashset_t set)
	Create a hashset iterator. The caller should then iterate over the hashset as follows:
int	hashset_iterator_has_next (hashset_itr_t itr)
	Return 1 if there is a next value in the hashset and 0 otherwise.
int	hashset_iterator_next (hashset_itr_t itr)
	Advance to the next value in the hashset. This returns a non-negative number (the current index) if there is a next item and -1 otherwise.
void *	hashset_iterator_value (hashset_itr_t itr)
	Returns the value at the current index. The called should check hashset_iterator_has_next before calling this.

hashset_iterator()

hashset_itr_t hashset_iterator

(

hashset_t

set

)

Create a hashset iterator. The caller should then iterate over the hashset as follows:

hashset_itr_t iterator = hashset_iterator(my_hashset);
while (hashset_iterator_next(iterator) >= 0) {
  void* my_value = hashset_iterator_value(iterator);
  ...
}
free(iterator);

The caller must call free() on this iterator after using it.

hashset_iterator_has_next()

int hashset_iterator_has_next

(

hashset_itr_t

itr

)

Return 1 if there is a next value in the hashset and 0 otherwise.

hashset_iterator_next()

int hashset_iterator_next

(

hashset_itr_t

itr

)

Advance to the next value in the hashset. This returns a non-negative number (the current index) if there is a next item and -1 otherwise.

hashset_iterator_value()

void * hashset_iterator_value

(

hashset_itr_t

itr

)

Returns the value at the current index. The called should check hashset_iterator_has_next before calling this.
