>but what is the hard part? is it not just a pause command in C++?
You should read a bit about real-time systems and how they are
implemented. You have no hope of getting millisecond resolution on a
system that is not designed for this.
All you can do at high level is maintain the average distance between
your invocations by using a cumulative timer and a tight loop. You'll
get as little jitter as possible given your OS allowance and you'll get
perfect interval time length average, that is, no drift.
