As well as the jack ring buffer, I've looked at several others now, and

complete structures are pushed or popped, would I be right in thinking

would only need to check on an all/none basis?
Have I missed something that could cause a partial data transfer?
the jack ring buffers are byte-oriented, so you do have to be careful.
however, if both the reader and writer only ever increment their respective
pointer/index in multiples of the same basic byte count, then you should be
OK.
if you use a C++ template ring buffer, then you necessarily cannot get
partial transfers.
