/*
* 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.
