/*
 *	A ring queue allows maximum utilization of memory for data storage and is
 *	ideal for input/output buffering. This module provides a highly effecient
 *	implementation and a vehicle for dynamic strings.
 *
 *	WARNING:  This is a public implementation and callers have full access to
 *	the queue structure and pointers.  Change this module very carefully.
 *
 *	This module follows the open/close model.
 *
 *	Operation of a ringq where rq is a pointer to a ringq :
 *
 *		rq->buflen contains the size of the buffer.
 *		rq->buf will point to the start of the buffer.
 *		rq->servp will point to the first (un-consumed) data byte.
 *		rq->endp will point to the next free location to which new data is added
 *		rq->endbuf will point to one past the end of the buffer.
 *
 *	Eg. If the ringq contains the data "abcdef", it might look like :
 *
 *	+-------------------------------------------------------------------+
 *  |   |   |   |   |   |   |   | a | b | c | d | e | f |   |   |   |   |
 *	+-------------------------------------------------------------------+
 *    ^                           ^                       ^               ^
 *    |                           |                       |               |
 *  rq->buf                    rq->servp               rq->endp      rq->enduf
 *     
 *	The queue is empty when servp == endp.  This means that the queue will hold
 *	at most rq->buflen -1 bytes.  It is the fillers responsibility to ensure
 *	the ringq is never filled such that servp == endp.
 *
 *	It is the fillers responsibility to "wrap" the endp back to point to
 *	rq->buf when the pointer steps past the end. Correspondingly it is the
 *	consumers responsibility to "wrap" the servp when it steps to rq->endbuf.
 *	The ringqPutc and ringqGetc routines will do this automatically.
