Detailed Description

CNE Ring

The Ring Manager is a fixed-size queue, implemented as a table of pointers. Head and tail pointers are modified atomically, allowing concurrent access to it. It has the following features:

• FIFO (First In First Out)
• Maximum size is fixed; the pointers are stored in a table.
• Lockless implementation.
• Multi- or single-consumer dequeue (default is single-consumer).
• Multi- or single-producer enqueue (default is single-producer).
• Bulk dequeue.
• Bulk enqueue.

Note: the ring implementation is not preemptible. Refer to Programmer's guide/Cloud Native Environment/Multiple pthread/Known Issues/cne_ring for more information.
