getloadavg and proc filesystem

[Andrew Miehs <andrew@2sheds.de>]

Hi all,

I am looking at writing some monitoring scripts from data out of the / 
proc filesystem
for monitoring cpu, idle, etc.

I have had a look at the source code for getloadavg.c, and wondering  
what happens if
the kernel changes the data in /proc/loadavg while getloadavg is  
doing its stuff.

This problem is even more likely to happen with /proc/cpuinfo...

Or does the proc filesystem somehow protect against this?

Thanks for any advice,

Andrew
