NAME
       getloadavg - get system load averages

SYNOPSIS
       getloadavg(loadavg, nelem)
	      double loadavg[];
	      int    nelem;

DESCRIPTION
       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  succes-
       sive  elements  of loadavg.  The system imposes a maximum of 3 samples, representing aver-
       ages over the last 1, 5, and 15 minutes, respectively.

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

SEE ALSO
       uptime(1), sysctl(3), sysctl(8).

HISTORY
       The getloadavg function appeared in 4.3BSD-Reno.

       This function replaces the 2.9BSD compatibility routine getla().
