Resource utilization information is kept in Mach. It is only copied over to BSD for the purposes of rusage(), and then only when the process exits. You are looking in the wrong place for the accounting information. Typically, at this point, we recommend that you do not use Mach calls, since this can change from software update to software update. Instead, popen() the "top" command, which is able to put its output in a machine-parsable form. If we change anything top relies on, we tend to notice it immediately and fix top at the same time, so this will insulate you from kernel structure andd algorithm changes (with the bonus of being portable to older versions of the OS without modifications).

Is it the right way to get the Kernel time/CPU time and User time for a process (Except using ps )? What is the jiffy value in seconds on Mac because if I get values I will have to convert it in seconds. This email sent to tlambert@apple.com This email sent to site_archiver@lists.apple.com
