hi,

the ringbuffer will be basically using the same algorithm as the
spsc_queue under the hood, but basically separate 'algorithm' from
'storage', right?

afaict the spsc_queue can already be used in shared memory, though
zero-copy is limited to pushing movable types and consuming via a
functor (haven't checked the code for a while, though). mmap for buffer
wrapping would be really cool to have, though ...

--
a more generic interface would be useful for some use cases, where you
can directly access the storage may be useful for some use cases, but
when i originally wrote the class, it didn't include it, as i was a bit
afraid that the interface might be a bit too fragile. but i don't have a
very strong opinion on this.
i suppose, you already had a look at the code of the spsc_queue already?
cheers,
