|
* top - a top users display for Unix
|
|
*
|
|
* SYNOPSIS: For FreeBSD-2.x and later
|
|
*
|
|
* DESCRIPTION:
|
|
* Originally written for BSD4.4 system by Christos Zoulas.
|
|
* Ported to FreeBSD 2.x by Steven Wallace && Wolfram Schneider
|
|
* Order support hacked in from top-3.5beta6/machine/m_aix41.c
|
|
* by Monte Mitzelfelt (for latest top see http://www.groupsys.com/topinfo/)
|
|
*
|
|
* This is the machine-dependent module for FreeBSD 2.2
|
|
* Works for:
|
|
* FreeBSD 2.2.x, 3.x, 4.x, and probably FreeBSD 2.1.x
|
|
*
|
|
* LIBS: -lkvm
