Please include the ability to determine the length of the current
contents (as a marcro?) so that buffers can be padded, as necessary,
since some hardware and some protocols require this.

Also consider protecting the structure with a mutex, at least in
kernel space (this would make the macro harder to write, which is
why I put it into a parenthetical, question-marjed statement).
