/*

* Top - a top users display for Berkeley Unix

|
*
|
|
* Defines required to access load average figures.
|
|
*
|
|
* This include file sets up everything we need to access the load average
|
|
* values in the kernel in a machine independent way. First, it sets the
|
|
* typedef "load_avg" to be either double or long (depending on what is
|
|
* needed), then it defines these macros appropriately:
|
|
*
|
|
* loaddouble(la) - convert load_avg to double.
|
|
* intload(i) - convert integer to load_avg.
|
|
*/
|

|
|
/*
|
|
* We assume that if FSCALE is defined, then avenrun and ccpu are type long.
|
|
* If your machine is an exception (mips, perhaps?) then make adjustments
|
|
* here.
|
|
*
|
|
* Defined types: load_avg for load averages, pctcpu for cpu percentages.
