KVM_GETLOADAVG(3)     DragonFly Library Functions Manual     KVM_GETLOADAVG(3)

NAME
     kvm_getloadavg -- get load average of the system

LIBRARY
     Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS
     #include <sys/types.h>
     #include <kvm.h>

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

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

DIAGNOSTICS
     If the load average was unobtainable, -1 is returned; otherwise, the num-
     ber of samples actually retrieved is returned.
