Yes. Partial writes are possible but are going have to take care of when you
write the remainder, and also cater for partial reads as well. These would
introduce some ugly timing issues between producer and consumer.

Well, saying 'just' might be an understatement - there are issues here too but
they should be less that writing partial structures.
There was mention of writing pointers to buffers, I would avoid this as well
for the possible case that you want to mount your ringbuffers in shared memory
between processes rather than between threads. It might not be your goal now
but it would be painful if that changed in the future.
