 Name:         »Suptime« - returns the current uptime and load 
               averages from the system.

 Gemdosnummer: 319 (0x013f)

 Deklaration:  int32_t Suptime ( int32_t *uptime, int32_t *loadaverage 
               );

 Beschreibung: This function returns the current uptime and load 
               averages from the system.

               uptime is a pointer to a LONG value that will be filled 
               with the current amount of seconds elapsed since last 
               reboot.

               loadaverage is a pointer to a three longword array, 
               that will be filled with the current load averages (for 
               last 1, 5 and 15 minutes).

               The load average value is calculated using the 
               following formula:

               sum += (new_load - old_load) * LOAD_SCALE;
               load_avg = sum / MAX_SIZE;

               where LOAD_SCALE is 2048, MAX_SIZE is the number of 5 
               second periods in the specified amount of time (12 for 
               1 min., 60 for 5 min. and 180 for 15 min). new_load is 
               the number of currently running processes, old_load is 
               the number of processes running previous time. A 
               'running' process is considered the one which is put 
               onto run or ready queue.

 Ergebnis:     Returns E_OK or a negative GEMDOS error code otherwise 
               (actually it may be only ENOSYS if the call is not 
               supported...).

 Verfügbar:    Available when a 'MiNT' cookie with a version of at 
               least 1.11 exists.
