Re: [ns2] How can I stop the simulator?

[kannan@catarina.usc.edu]

``halt'' in scheduler.cc is not a Simulator class procedure.
I expect that your $ns is an object in the Simulator class.
You need the following wrapper to get "$ns halt" to work:

+       $scheduler_ halt

  Simulator set NumberInterfaces_ 0
  
  Simulator instproc simplex-link { n1 n2 bw delay arg } {


You should apply this using "patch -p" from the top-level ns-2 directory.
