Hi all,
Hopefully simple question:
What is the unit of the `int timeo` parameter in sleep(9)? Is it the timeout in milliseconds? Or would 1 mean a second?
Related, what does the `hz` variable mean and why is it used? I see instances of timo's in multiples of hz (ie, hz * 10). OpenGrok shows it defined in a few different places and its not clear to me which it is.
Thank you!
