Hello Sanjay,
One suggestion - its probably better to precede the output lines with cpu no. As currently output from child processes are intermixed as below and difficult to co-relate.
jiffies are : 10000 usecs found 4 cpu(s) duration: 120 secs, #sleep: 1200, delay: 100000 us duration: 120 secs, #sleep: 1200, delay: 100000 us duration: 120 secs, #sleep: 1200, delay: 100000 us duration: 120 secs, #sleep: 1200, delay: 100000 us counter value 4072718528 test duration: 120.057526 secs deviation 0.000479 counter value 3914063589 test duration: 120.057335 secs counter value 4015937716 test duration: 120.057430 secs deviation 0.000479 deviation 0.000478 counter value 411037603 test duration: 120.062716 secs deviation 0.000523

Hello Sanjay, As far I know, if option argument is 0, the parent will wait for Looks like waiting is done if childs exit. I checked for the offlined CPU case, if there are no child processes, waitpid returns -1. Setting errno as "no child processes" specified child pid to terminate, its not for immediate return asin case of WNOHANG. This is probably the intended use of the code (author will be able to confirm). Changing 0 to WNOHANG macro will change the meaning of the code. Also, from header file - #define WNOHANG 0x00000001
sorry i referred wrong document WNOHANG is defined as 1, not zero. Which makes me think of two cases below - 1. If the real intended purpose is to not to wait infinitely, replacing [...]-- sanjay
