 	      msgQDemo.c
 
 DESCRIPTION -
 	      This demo demonstrates intertask communication using Message Queues.
 	      It creates a Message Queue for interTask communication between the
 	      producerTask and the consumerTask. It spawns the producerTask that creates
 	      messages and sends messages to the consumerTask using the message queue.
 	      It spawns the consumerTask that reads messages from the message queue.
 	      After consumerTask has consumed all the messages, the message queue is
 	      deleted.
 
 	      To run this code invoke the function msgQDemo()
 
 RUNNING DEMO -
 	      Place the msgQDemo.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.
 
 	      Run msgQDemo() on vxworks target.
 
 TESTED ON -   Host/Target : Solaris 2.5.1 / mv1604
 	      VxWorks     : 5.3.1
