[ndnSIM] Print() in ndn-pit-impl.h

[Alex Afanasyev]

Hi Kang,

Print method is defined to return nothing:

  virtual void
  Print (std::ostream &os) const;

So, you cannot really use it they way you tried.  But simple change should fix your problem:

  std::cout << Simulator::Now ().ToDouble (Time::S) << "\t"
            << node->GetId () << "\t"
            << Names::FindName (node) << "\t"
            << pit->GetSize () << "\n";

  pit->Print(std::cout);
  std::cout << "\n";

PS
Not sure what happened, but somehow either your email client or the smtp provider completely destroyed format of your message (I had to dig in into the message source to get readable text back).  You may try to use the HTML format next time.
