/*

 *      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.
