1 /*
2  *  Top - a top users display for Berkeley Unix
3  *
4  *  Defines required to access load average figures.
5  *
6  *  This include file sets up everything we need to access the load average
7  *  values in the kernel in a machine independent way.  First, it sets the
8  *  typedef "load_avg" to be either double or long (depending on what is
9  *  needed), then it defines these macros appropriately:
10  *
11  *	loaddouble(la) - convert load_avg to double.
12  *	intload(i)     - convert integer to load_avg.
