NAME
     kvm_getloadavg -- get system load averages

LIBRARY
     Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS
     #include <sys/resource.h>

     int
     kvm_getloadavg(kvm_t *kd, double loadavg[], int nelem);

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

RETURN VALUES
     If the load average was unobtainable, -1 is returned; otherwise, the number of samples actu-
     ally retrieved is returned.
