FILE LIST -
	      pipeServer.c

DESCRIPTION -
	     This demo demonstrates intertask communication using pipes.
	     ServerStart() initializes a server task to execute functions
	     at a low priority and uses pipes as the communication
	     mechanism.

	     serverSend() sends a request to the server to execute a
	     function at the server's  priority using pipe device.

	     To run the code invoke the function serverStart().

RUNNING DEMO -
	     Place the pipeServer.c file in your <Tornado> dir. Depending
	     on the target you have, define the CPU in your compile line 
	     and use the Makefile in the BSP dir. to compile.

	     A host function such as i() cannot be used as the function
	     argument to serveSend.
	     eg: -> serverSend(i,"tShell") will not work
	     However if you wish to do that then make sure to add
	     INCLUDE_CONFIGURATION_5_2 and INCLUDE_DEBUG in configAll.h and
	     re-make vxWorks.

TESTED ON -   Host/Target : Solaris 2.5.1 / mv1604
	      VxWorks     : 5.3.1

	      EXAMPLE COMPILE LINE - (use the MakeFile in the BSP)
			    make CPU=PPC604 pipeServer.o
		     
% make pipeServer.o

OUTPUTS/LOGFILE -

On VxWorks target:
==================

-> ld <pipeServer.o
value = 2578392 = 0x2757d8
-> serverStart   
value = 0 = 0x0
-> serverSend (printf,"Hello World. \n")
value = 0 = 0x0

The Output on Console:
======================
Hello World.
