You need to change the "double t_rtxcur_ " to "TracedDouble t_rtxcur_" in
tcp.h at the first.
Then you need to add some source code to record your variable in
TcpAgent::traceVar fuction in the file of tcp.cc
At last you need to recomplie the ns.
I am not sure it can success.
Just try and then tell me the results,ok?
