FILE LIST -
	memPartSend.c
	memPartReceive.c

DESCRIPTION -
	     These files create a user-defined partition and store the 
	     shared data in this new partition. A shared semaphore is
	     used to protect the data.

	     The file memPartSend.c writes to the user-defined shared memory
	     partition.
	     The file memPartReceive.c reads from the user-defined shared
	     memory partition. 

	     To run this demo invoke the function memPartSend() from 
	     memPartSend.c followed by the function memPartReceive()
	     from the memPartReceive.c file.

RUNNING DEMO - 
	     Place the memPartSend.c and memPartReceive.c 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.

	     Include INCLUDE_SM_OBJ in configAll.h, and re-make vxWorks.

	     Install VxMP into your Tornado tree before running this code.

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