 CVS :        $Id: test1.c,v 1.1.1.1 2002-09-02 09:37:48 pj Exp $

 File:        $File$

 Revision:    $Revision: 1.1.1.1 $

 Last update: $Date: 2002-09-02 09:37:48 $

 ------------

 Test Number 1:

 this test is a simple main() function with other 2 task

 This test has to be compiled with init1.c, that introduce 2 RR levels

 with a timeslice of 300us (!)

 This test can be useful to test functions like

 task_nopreempt

 task_preempt

 task_create

 task_activate

 task_delay

 group_activate

 normal task termination (task_abort)

 normal system termination (sys_end)

 standard atexit functions (the keyboard...)
