Re: [ns] Queue monitoring in a lan

[Neeraj - Khandelwal <neerajk@cs.tamu.edu>]

hi again,
excuse the naive question, being new to ns doesnt help.
  how can I record the simulation time from inside the mac_802_3.cc file
before a particular event? can  I straightaway get a handle to the timer
(how) and use some of its method?

thanks
Neeraj
