      semTask1.c
      semTask2.c

DESCRIPTION -
	     The following code example creates two tasks executing on
	     different CPUs and using shared semaphores. The routine
	     semTask1( ) creates the shared semaphore, initializing
	     the state to full. It adds the semaphore to the name database
	     (to enable the task on the other CPU to access it), takes the
	     semaphore, does some processing, and gives the semaphore. 
	     The task semTask2( ) gets the semaphore ID from the database,
	     takes the semaphore, does some processing, and gives the
	     semaphore.

RUNNING DEMO -
	     Place semTask1.c and semTask2.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.

	     Add INCLUDE_SM_NET , INCLUDE_SM_SEQ_ADDR and INCLUDE_SM_OBJ
	     in the config.h file in the BSP

	     Install VxMP into your Tornado tree before running this code.
             
	     Re-make vxWorks and reboot your board, before running.

	     To run this demo invoke the semTask1() first followed by
	     the semTask2().
