NAME
       cputime, times - cpu time in this process and children

SYNOPSIS
       #include <u.h>
       #include <libc.h>

       int    times(long t[4])

       double cputime(void)

DESCRIPTION
       If  t  is  non-null,  times fills it in with the number of milliseconds spent in user code, system calls, child processes in user code, and
       child processes in system calls.  Cputime returns the sum of those same times, converted to seconds.  Times returns the real time, in  mil-
       liseconds used by the process so far.

       These functions read /dev/cputime, opening that file when time is first called.
