Hi,
I have a question about tracing a C++ variable from tcl. I would like
to trace the v_baseRTT_ variable for TCP vegas. How do I go about
doing that?
I tried binding the variable in tcp.cc by doing:
bind("v_baseRTT_", &v_baseRTT_);
I then tried to log v_baseRTT_ from tcl by doing:
set base_rtt [$tcpSource set v_baseRTT_]
where $tcpSource is a Vegas TCP source.
The problem is that the tcl interpreter does not recognize the
v_baseRTT variable.
I also tried to adding the following line of code to
delay_bind_dispatch() in tcp.cc:
if (delay_bind(varName, localName, "v_baseRTT_", &v_baseRTT_ ,
tracer)) return TCL_OK;
NS did not like that last line of code though. Any help would be
greatly appreciated. Thanks!
Best,
Karim
