getloadavg(3c)

Standard C Library Functions                                    getloadavg(3C)



NAME
       getloadavg - get system load averages

SYNOPSIS
       #include <sys/loadavg.h>

       int getloadavg(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 successive elements of loadavg[]. The
       system imposes a maximum of 3 samples, representing averages  over  the
       last  1,  5,  and  15  minutes,  respectively.  The LOADAVG_1MIN, LOAD‐
       AVG_5MIN, and LOADAVG_15MIN indices, defined in <sys/loadavg.h>, can be
       used  to extract the data from the appropriate element of the loadavg[]
       array.

RETURN VALUES
       Upon successful completion, the number of samples actually retrieved is
       returned.  If  the  load  average  was unobtainable, −1 is returned and
       errno is set to indicate the error.

ERRORS
       The getloadavg() function will fail if:

       EINVAL    The number of elements specified is less than 0.


USAGE
       If the caller is in a non-global zone and the pools facility is active,
       the  behavior  of  getloadavg()  is equivalent to that of pset_getload‐
       avg(3C) called with psetid set to PS_MYID.
