queue->get (ul_oocbs)

	item.g.r = get(queue.s.r)

	This method returns the element at the head of the Queue,

	queue             a pointer to the queue (structure of type Queue)

	This function returns:

	a pointer to the item at the head of the Queue.

	create_Queue()    the constructor for instances of the Queue class

	C/C++ usage:

	#include "queue.h"
	Queue	*queue;
	int	item;
	int	length;
	void	*ptr;

	ptr = (*queue->get)(queue);
	if (ptr != (void *) NULL)
	    item = *ptr;

	data item given to it for the "put" operation. It is a pointer
	to this allocated space that is returned by this method.
	Therefore the user of the Queue class must be sure to free
	this pointer when finished with it, or else memory leaks will
