NOTES
       Note

	       On Windows getrusage(3) will only return the following members:

		     o "ru_stime.tv_sec"

		     o "ru_stime.tv_usec"

		     o "ru_utime.tv_sec"

		     o "ru_utime.tv_usec"

		     o "ru_majflt" (only if $who is RUSAGE_SELF)

		     o "ru_maxrss" (only if $who is RUSAGE_SELF)

	       If getrusage(3) is called with $who set to 1 ( RUSAGE_CHILDREN), then resource usage for threads are collected (meaning that inter-
	      nally the function is called with RUSAGE_THREAD).

       Note

	       on BeOS 2000, only the following members are returned:

		     o "ru_stime.tv_sec"

		     o "ru_stime.tv_usec"

		     o "ru_utime.tv_sec"

		     o "ru_utime.tv_usec"
