NAME

       getloadavg - get system load averages

SYNOPSIS

       #define _BSD_SOURCE         /* See feature_test_macros(7) */
       #include <stdlib.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.

RETURN VALUE

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

VERSIONS

       This function is available in glibc since version 2.2.
