DESCRIPTION

15       The getloadavg() function returns the number of processes in the system
16       run queue averaged over various periods of time.  Up to  nelem  samples
17       are  retrieved  and  assigned to successive elements of loadavg[].  The
18       system imposes a maximum of 3 samples, representing averages  over  the
19       last 1, 5, and 15 minutes, respectively.

RETURN VALUE

22       If  the  load  average was unobtainable, -1 is returned; otherwise, the
23       number of samples actually retrieved is returned.
