Operating Systems Solaris Infinite for loop is taking too much CPU usage %

Old 06-23-2009
Hi All,
Initially I had a doubt that my program is taking this much CPU util because of the for loop more than 100000 times, from the reply I have got that it has to take that much CPU time. So I will try to analyse the code in different aspect.

Thanks to all for your comments.

clock(3C)																 clock(3C)

NAME
clock() - report CPU time used SYNOPSIS
DESCRIPTION
returns the amount of CPU time (in microseconds) used since the first call to The time reported is the sum of the user and system times of the calling process and its terminated child processes for which it has executed , or (see wait(2) , system(3S), and popen(3S)). To deter- mine the time in seconds, the value returned by should be divided by the value of the macro The resolution of the clock varies, depending on the hardware and on software configuration. If the processor time used is not available or its value cannot be represented, the function returns the value WARNINGS
The value returned by is defined in microseconds for compatibility with systems that have CPU clocks with much higher resolution. Because of this, the value returned wraps around after accumulating only 4295 seconds of CPU time (about 72 minutes). DEPENDENCIES
The default clock resolution is 10 milliseconds. SEE ALSO
times(2), wait(2), system(3S), thread_safety(5). STANDARDS CONFORMANCE
