Here's a utility that's designed for this sort of problem:
Basically, it lets you use an array like a FIFO, but without the
end-of-buffer problem. Even if you don't use it, it's a neat hack
that's worth appreciating just for that. :)
It's probably overkill for what you're working on. Your memmove
solution should be sufficient.
