    @param proc_dir: The directory to use for process information.
    @param jiffies: The value to use for jiffies per second.
    @param boot_time: An alternate value to use for the last boot time.  If
        None, the system last boot time will be used.
    @param uptime: The uptime value to use (for unit tests only).

        Parse the /proc/<pid>/cmdline and /proc/<pid>/status files for
        information about the running process with process_id.

        The /proc filesystem doesn't behave like ext2, open files can disappear
        during the read process.

    Implement ps' algorithm to calculate the percentage cpu utilisation for a
    process.::

    unsigned long long total_time;   /* jiffies used by this process */
    unsigned pcpu = 0;               /* scaled %cpu, 99 means 99% */
    unsigned long long seconds;      /* seconds of process life */
    total_time = pp->utime + pp->stime;
    if(include_dead_children) total_time += (pp->cutime + pp->cstime);
    seconds = seconds_since_boot - pp->start_time / hertz;
    if(seconds) pcpu = (total_time * 100ULL / hertz) / seconds;
    if (pcpu > 99U) pcpu = 99U;
    return snprintf(outbuf, COLWID, "%2u", pcpu);
