This directory contains a set of simple examples, useful to understand

How to make a Shark application.

Text mode demos:

- hello.c   --> a hello world application

- timer.c   --> tests if the time reads are always increasing

	        (useful for debugging purposes)

- sig.c     --> simple example that sends signals

- semdemo.c --> simple example that uses a semaphore for mutual exclusion

- pidemo.c  --> simple example that uses PI  mutexes between NRT and Hard tasks

- pcdemo.c  --> simple example that uses PC  mutexes between NRT and Hard tasks

- srpdemo.c --> simple example that uses SRP mutexes between NRT and Hard tasks

- mdemo.c   --> simple example that uses a mutex, initialized with whatever

                protocol you want ;-)

- aster.c   --> Wow! the original Hartik ASTER demo!!! (EDF, CABs, ...)

- aster1.c  --> a -lot- of periodic tasks that are created and then die

	        (6 seconds demo)

- aster2.c  --> a simple stress test: a lot of tasks are created until Utot=1;

	        uses jet functions to dump statistics. (60 seconds demo)

- aster3.c  --> aster2 + 8 tasks handled by 2 different TBS servers

- aster4.c  --> aster3 + CBS tasks + Shutdown demo with system tasks

- aster5.c  --> aster3 + only CBS tasks + mutexes... Really interesting!

- aster6.c  --> aster5 + Polling Server to serve the JetCtrl task

- aster7.c  --> another aster clone with Rate monotonic and Polling server

- aster8.c  --> aster5 + Sporadic Server

- preempt.c --> simple test for CBS, task_preempt, task_nopreempt, and

	        save/skip arrivals

- pcidemo.c --> PCI Bus scan

- jointest.c--> Simple test that uses the task_join primitive

- condtest.c--> Simple test that uses condition variables

- intsem.c  --> Simple test that uses internal semaphores

Graphical demos:

- fly.c     --> Random flies going around the screen

- ego.c     --> Periodic tasks that writes a phrease on the screen

- cabs.c    --> Example that uses cabs

Note on the init files:

- ihello.c   (RR+dummy)

- isemdemo.c (iaster1+Semaphores)

- iaster1.c  (EDF+RR+dummy)

- iaster3.c  (EDF+RR+TBS(0.1)+TBS(0.3)+dummy)

- iaster4.c  (iaster3+CBS)

- initfile.c (EDF+CBS+RR+dummy, SEMaphores, CABS, HARTPORTs and Keyboard)
