+ * @file
+ * @b EXPERIMENTAL: this API may change without prior notice
+ * It is not recommended to include this file directly.
+ * Please include <rte_ring_elem.h> instead.
+ *
+ * Ring Peek API
+ * Introduction of rte_ring with serialized producer/consumer (HTS sync mode)
+ * makes possible to split public enqueue/dequeue API into two phases:
+ * - enqueue/dequeue start
+ * - enqueue/dequeue finish
+ * That allows user to inspect objects in the ring without removing them
+ * from it (aka MT safe peek).
+ * Note that right now this new API is avaialble only for two sync modes:
+ * 1) Single Producer/Single Consumer (RTE_RING_SYNC_ST)
+ * 2) Serialized Producer/Serialized Consumer (RTE_RING_SYNC_MT_HTS).
+ * It is a user responsibility to create/init ring with appropriate sync
+ * modes selected.
+ * As an example:
+ * // read 1 elem from the ring:
+ * n = rte_ring_dequeue_bulk_start(ring, &obj, 1, NULL);
+ * if (n != 0) {
+ *    //examine object
+ *    if (object_examine(obj) == KEEP)
+ *       //decided to keep it in the ring.
+ *       rte_ring_dequeue_finish(ring, 0);
+ *    else
+ *       //decided to remove it from the ring.
+ *       rte_ring_dequeue_finish(ring, n);
+ * }
+ * Note that between _start_ and _finish_ none other thread can proceed
+ * with enqueue(/dequeue) operation till _finish_ completes.
