public class L_Queue
extends org.bridj.StructObject

queue.h
Expandable pointer queue for arbitrary void* data.
The L_Queue is a fifo that implements a queue of void* pointers.
It can be used to hold a queue of any type of struct.
Internally, it maintains two counters:
nhead: location of head (in ptrs) from the beginning
of the array.
nelem: number of ptr elements stored in the queue.
The element at the head of the queue, which is the next to
be removed, is array[nhead]. The location at the tail of the
queue to which the next element will be added is
array[nhead + nelem].

As items are added to the queue, nelem increases.
As items are removed, nhead increases and nelem decreases.
Any time the tail reaches the end of the allocated array,
all the pointers are shifted to the left, so that the head
is at the beginning of the array.
If the array becomes more than 3/4 full, it doubles in size.
The auxiliary stack can be used in a wrapper for re-using
items popped from the queue. It is not made by default.
For further implementation details, see queue.c.
