frank_mod.o / frank_app:
========================

This example features two real-time tasks that can potentially perform some
real work, e.g. data collection. Here they simply write strings into FIFOs.

The real-time part creates three RT-FIFOs: two for data passing, and one for
control. Then it creates two real-time tasks and registers a handler with the
control FIFO.

Real-time and non-real-time parts both agree on the format of control messages
(see file control.h). Whenever Linux tasks writes to the control FIFO, the
handler is invoked. In the handler the RT-tasks are started and stopped.

The real-time tasks are almost identical. They keep writing strings into FIFOs.
In the end of each loop each of them makes a request to deschedule itself
until the beginning of the next period.

The Linux program (app) opens RT-FIFO devices, starts RT-tasks and enters the
loop in which it reads and prints the data produced by RT-tasks.

To run type `make; make test'

rt-handler.o:
=============

Simple example of rtf_create_rt_handler.

a producer thread produces data  (simple and unsigned long i) and rtf_put's
it into fifo 0 -> this triggers the rtfifo realtiem handler p_to_c that wakes 
up the consumer thread which then rtf_get's the data and prntk's it.
