LOADAV(3)           UNIX Programmer's Manual            LOADAV(3)

NAME
     loadav - get load average

SYNOPSIS
     loadav(vec)
     double vec[3];

DESCRIPTION
     _L_o_a_d_a_v returns the load average on the system.  The three
     numbers returned are the 1, 5, and 15 minute load averages.
     A load average is the average length of the run queue over
     the indicated period of time.  It suggests what fraction of
     the CPU you would get for a CPU bound process.  For example,
     a load of 3.00 indicates you would get 1/3 of the CPU.  The
     higher the load, the more loaded the system.  The different
     numbers can be used to give some indication of whether the
     load is going up or down.

BUGS
     Only measures the load on the CPU.  If the system is I/O
     bound, it won't indicate the true load.
