kernel/system up time

Is there a library function that tells me how long the system or the kernel has been up.

Thanks
IFti

"uptime" will give you the info. If you want the text file, it's /proc/uptime.

dunno, but isn't it possible to just read /proc/uptime as text with the functions from stdio.h?

That's a good idea. Thanks.
When I did cat /proc/uptime it gave me
97983.95 85870.88

How to read from it. What are these 2 values and are they in seconds?

from "man proc"...
"""uptime This file contains two numbers: the uptime of the system (seconds), and the amount of time spent in idle process (seconds)."""

iftiuk,
You can also download gkrellm as it has a running counter of machine uptime towards the bottom.
