-: Does  DJGPP support getrusage () ?

Here's what the docs have to say about getrusage:

------
This function returns information about the running process. Currently,
the only field that is computed is this:

struct rusage {
  struct timeval ru_utime;  /* total time used by process */
};

The remainder of the fields are set to zero. 

The who parameter must be RUSAGE_SELF or RUSAGE_CHILDREN.
------

So, on DOS, it doesn't seem that `time' could report much of
interest, anyway.

struct rusage {
  struct timeval ru_utime;      /* user time used */
  struct timeval ru_stime;      /* system time used */
  long ru_maxrss;               /* integral max resident set size */
  long ru_ixrss;                /* integral shared text memory size */
  long ru_idrss;                /* integral unshared data size */
  long ru_isrss;                /* integral unshared stack size */
  long ru_minflt;               /* page reclaims */
  long ru_majflt;               /* page faults */
  long ru_nswap;                /* swaps */
  long ru_inblock;              /* block input operations */
  long ru_oublock;              /* block output operations */
  long ru_msgsnd;               /* messages sent */
  long ru_msgrcv;               /* messages received */
  long ru_nsignals;             /* signals received */
  long ru_nvcsw;                /* voluntary context switches */
  long ru_nivcsw;               /* involuntary context switches */
};
