                     31: .I Getloadavg
                     32: returns the number of processes in the system run queue
                     33: averaged over various periods of time.  Up to
                     34: .I nelem
                     35: samples are retrieved and assigned to successive elements of
                     36: .I loadavg[].
                     37: The system imposes a maximum of 3 samples, representing averages
                     38: over the last 1, 5, and 15 minutes, respectively.
                     39: .SH "SEE ALSO"

                     42: If the load average was unobtainable, \-1 is returned; otherwise,
                     43: the number of samples actually retrieved is returned.
