It is not recommended to include this file directly. Please include <rte_ring.h> instead.
Contains functions for serialized, aka Head-Tail Sync (HTS) ring mode. In that mode enqueue/dequeue operation is fully serialized: at any given moment only one enqueue/dequeue operation can proceed. This is achieved by allowing a thread to proceed with changing head.value only when head.value == tail.value. Both head and tail values are updated atomically (as one 64-bit value). To achieve that 64-bit CAS is used by head update routine.

static |
Enqueue several objects on the HTS ring (multi-producers safe).
| r | A pointer to the ring structure. |
| obj_table | A pointer to a table of objects. |
| esize | The size of ring element, in bytes. It must be a multiple of 4. This must be the same value used while creating the ring. Otherwise the results are undefined. |
| n | The number of objects to add in the ring from the obj_table. |
| free_space | if non-NULL, returns the amount of space in the ring after the enqueue operation has finished. |

static |
Dequeue several objects from an HTS ring (multi-consumers safe).
| r | A pointer to the ring structure. |
| obj_table | A pointer to a table of objects that will be filled. |
| esize | The size of ring element, in bytes. It must be a multiple of 4. This must be the same value used while creating the ring. Otherwise the results are undefined. |
| n | The number of objects to dequeue from the ring to the obj_table. |
| available | If non-NULL, returns the number of remaining ring entries after the dequeue has finished. |
