I cannot comment on atomics op, but we have done rather exhaustive testing of

existing ringbuffer implementations on this list in the past.


The small test suite doesn't include any benchmarks, but it does perform

integrity checks which, at the time, allowed to fix a bug in the JACK ringbuffer.


The code tests and includes 4 implementations: JACK ringbuffer, PortAudio

ringbuffer, FFMpeg FIFO, and Fons' LFQ. You can check it out and run it with:


$ svn co http://svn.samalyse.com/misc/rbtest

$ cd rbtest

$ make test


There is no dependency. Maybe that you could use these tests (especially

test-int-array) to check data integrity with your implementation.


Hope that helps
