UTSL :-)

int
getloadavg(loadavg, nelem)
        double loadavg[];
        int nelem;
{
        struct loadavg loadinfo;
        int i, mib[2];

        mib[0] = CTL_VM;
        mib[1] = VM_LOADAVG;
        size = sizeof(loadinfo);
        if (sysctl(mib, 2, &loadinfo, &size, NULL, 0) < 0)
                return (-1);

        nelem = MIN(nelem, sizeof(loadinfo.ldavg) / sizeof(fixpt_t));
        for (i = 0; i < nelem; i++)
                loadavg[i] = (double) loadinfo.ldavg[i] / loadinfo.fscale;
        return (nelem);
}
