DESCRIPTION    [Toc]    [Back]

     The getloadavg() function returns the number of processes in the system
     run queue 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.

DIAGNOSTICS    [Toc]    [Back]

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