Precise thread sleep needed. Max 1ms error

Question

I have thread that runs loop. I need that loop to be run once every 5ms (1ms error). I know that Sleep() function is not precise.

Do you have any suggestions?

Update. I can't do it other way. At the end of loop I need some kind of Sleep. I don't want to have 100% CPU loaded either.

Answer 1

From the question tags I suppose you are on windows. Take a look at Multimedia Timers, they advertise precision under 1ms. Another options is to use Spin Locks but this will basically keep a cpu core at maximum usage.
