Difference between LockFreeQueue, RingBufferQueue and kfifo_queue?

[rsend]

Hi,
I'm looking for a shared memory queue implementation I can use for sharing data with processes bidirectionally. I see in samples that you are demonstrating a kfifo_queue, but what are LockFreeQueue and RingBufferQueue in that case? Do you have further documentation for this project?

Thanks,
R
