It's not clear to me how much this is intending to write/read. If the
entire buffer, we should probably use the buffer size.
sizeof(*writebuffer) is a single byte, no?

Also, there are other instances of the same thing throughout this file.
I think they need to be consistent, in any event, for the test to work.
