As well as the jack ring buffer, I've looked at several others now, and their
example code. The most significant thing that seems to be different about them
(from a usage point of view) is the way they handle overflows. However, if the
buffer size is defined as an exact multiple of the data type/structure and only
complete structures are pushed or popped, would I be right in thinking that you
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.
