[ndnSIM] How to deal with just arrived Data Packets in a custom way

[Igor]

Hi Alex,

I decided to use the code you provided as the base to build my own logic. I
believe the erros that I reported in the previous e-mail was due to my lack
of c++ experience.

Thank you so much for your fast and precise help.

Igor Ribeiro.
