CVS : $Id: ptest1.c,v 1.1.1.1 2002-09-02 09:37:47 pj Exp $
File: $File$
Revision: $Revision: 1.1.1.1 $
Last update: $Date: 2002-09-02 09:37:47 $
------------
Posix test 1:
the main task create 4 tasks, J1, J2, J3, J4
at t = 0.2 sec. it raise a signal to J1
at t = 0.4 sec. it raise a signal to J2
at t = 0.8 sec. it kill J4
J1: it simply calls sigwait
J2: it simply calls sigwaitinfo
J3: it simply calls sigtimedwait with a timeout of 0.5 sec.
J4: it simply calls sigtimedwait with a -long- timeout
(J4 will be killed by main)
non standard function used:
cprintf
sys_gettime
keyboard stuffs
sys_end
