[ns-users] Printing Protected Variables (seqno)

[rik@scs.leeds.ac.uk]

I have a packet structure which contains a protected 'seqno_' variable,
just the same as in UDP.h.

I would like to output this variable in my TCL script. Could anyone
provide a snippet to do this? I currently have:

-----------------------
Agent/Ping instproc recv {from rtt} { 
	$self instvar node_

	puts "node [$node_ id] received ping ack from $from \\
		  with round-trip-time $rtt ms."

# I would like to output the sequence number 'seqno_' here.
	
}
-----------------------

many thanks,
rik wade
