              demoMy.mib snmpTask.c  snmpTask.h

DESCRIPTION - 
              This demo allows an SNMPv1/v2c manager to monitor the task
	      table in a target. All the task related variables can be 
	      looked up individually and relevant ones can be altered. 
	      New tasks can be spawned and existing ones can be deleted.
	      Incase of set failures, this code will not restart a task 
	      if it had been deleted.

RUNNING DEMO - 
              See DESCRIPTION and CAVEAT in the source code.

	      You might have to change the undo routine to suit your
	      requirements.
                   
              Place the snmpTask.c file in your <Tornado>/src/snmpv1/agent
              dir. Depending on the target you have, define the CPU 
	      in your compile line and use the Makefile in the agent dir.
	      to compile. The header file for this code is snmpTask.h. You 
	      can insert all the information from the snmpTask.h file into
	      a suitable header file in the target/h/snmp dir.
