How to use nanosleep for sleeping random amounts of time? (2 answers)

Closed 9 years ago.

I know it's a newbie question but I am struggling with this and don't understand nanosleep() well enough.

How can I make a process sleep a random time between 100 and 200 miliseconds?

Answer 1

A millisecond is (corrected, sorry, blah...) 1,000,000 nanoseconds. Multiply appropriately.
