struct _sds_queue_node * head
struct _sds_queue_node * tail
void(* value_free_fn )(void *value)

The pointer to the current active head node. This is the 'next' node that will be dequeued and acted upon during the dequeue (pop) operation.

If there are remaining nodes when the queue is destroyed, the queue will be drained and this free function called on the value of within.
