4Why do you want to sleep? In my experience the best way to handle problems that involve sleeping is not to sleep in the first place. – David Heffernan Apr 23 '11 at 18:24

**"sleep" for less than a millisecond in C++**. Then why should sleep? – Harry Joy Apr 23 '11 at 18:26

I getting continuous input, but I need to sample it every 100 microseconds. – Idov Apr 23 '11 at 18:27

I guess you will need some sort of a real time OS in order to sleep less than a ms. – snoofkin Apr 23 '11 at 18:28

You're not going to achieve 100 microsecond timing on standard windows without a device driver. Preferably an RTOS. – Steve Fallows Apr 23 '11 at 18:29

1I don't think you'll find a timer with much better resolution than that. I think busy loop is what you want. – David Heffernan Apr 23 '11 at 18:29

No. Under Windows, even without sleeping you can't ensure that two consecutive instructions will be carried out with less than a millisecond between them.
