Up to .I nelem samples are retrieved and assigned to successive elements of .I loadavg[]. The system imposes a maximum of 3 samples, representing averages over the last 1, 5, and 15 minutes, respectively. .SH "SEE ALSO" uptime(1), nlist(3), kmem(4) .SH DIAGNOSTICS If the load average was unobtainable, \-1 is returned; otherwise, the number of samples actually retrieved is returned. .SH BUGS Programs using this utility must have read permission on .I /dev/kmem.
