[ns] A new instproc for Node!

[Sowmya Manjanatha <sowmyam@mars.iol.unh.edu>]

Hi,

I created a new instproc for Node, something like

Node instproc get-conn { arg1 arg2 } {

puts "Node::get-conn"


}

in the file ns-node.tcl, compiled ns and tried to invoke this
function from one of my scripts. This resulted in a segmentation
fault and I figure that the script is not even recognizing this
function since every other command before this line in the script
was executed and as I have indicated the very first line which is
a print did not get through.

gdb gave me the following sequence of class methods that I cannot
decipher.

Can anyone tell me if I ought to do anything more than the above.


Thanks,
Sowmya.
