Re: timeout value less than timer granularity

["Daniel Marian" <daniel_marian@linuxmail.org>]

Hello Amit/All,
   If the timer granularity cannot go below 10ms then how is the functionality of the nanosleep and usleep
system calls in Linux implemented ?

Is it an approximate ?
How do I know the clock ticks in a Linux box(i386) 
Like /proc/cpuinfo etc.

Is the timer granularity in the kernel different?

I feel all the above are newbie questions sorry abt it

TIA
kind regards,
daniel marian.
