     CPUTIME(2)                                             CPUTIME(2)

     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 mil-
          liseconds 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 milliseconds used by the
          process so far.

          These functions read /dev/cputime, opening that file when
          they are first called.
