According to this article http://kerneltrap.org/node/11773 it says ' each
level of nice adds or substracts 10% of CPU utilization, "*the '10% effect'
is relative and cumulative: from _any_ nice level, if you go up 1 level,
it's -10% CPU usage, if you go down 1 level it's +10% CPU usage.*" '

Looked in to the clock_gettime() it is not going to work as it has to be
called inside the process, also it gives the total time taken for a
function to complete. This will include the time other processes was using
the CPU as well ryt?

I don't quite understand what you're trying to do here. Is the goal to
make a process consume more processor? If you run a process at a higher
priority, it isn't guaranteed to take more cpu time. For example, a
heavily i/o bound process could just be woken up a bit faster after
blocking, but sti
See also "man clock_gettime" for CLOCK_PROCESS_CPUTIME_ID
or CLOCK_THREAD_CPUTIME_ID, which would need to be called by the process or
thread itself.

I looked in to the /proc//stat and it gives some use full information
about the process. There are many time variables and what should I use to
calculate the CPU time?
Also is there a way to measure if the CPU time slice has increased or the
frequency of getting the CPU has in creased after a reni
