rusage

       rusage() - reports information gathered by the getrusage()
       system call

SYNOPSIS

       mapping rusage( void );

DESCRIPTION

       This  efun   collects   information   gathered   via   the
       getrusage()  system  call.   Read the getrusage() man page
       for more information on  what  information  will  be  col-
       lected.   Some  systems do not have the getrusage() system
       call but do have the times() system call.  On  those  sys-
       tems,  only  "utime" and "stime" will be available.  Times
       are reported in milliseconds.

       Here is an example usage of rusage():

         void
         create()
         {
             mapping info;

             info = rusage();
             write("user time = " + info["utime"] + "ms\n");
             write("system time = " + info["stime"] + "ms\n");
         }

       The available fields are:

              utime, stime, maxrss, ixrss, idrss, isrss,  minflt,
              majflt,  nswap,  inblock,  oublock, msgsnd, msgrcv,
              nsignals, nvcsw, nivcsw.
