Re: [ns] Accessing object created in Tcl from C++
Hi Shafiq, To access a variable declared in your TCL script, you can use the following method :- Tcl& tcl = Tcl::instance(); tcl.lookup(char* s); The 'lookup()' function of Tcl class takes a pointer to the name of the variable in the TCL script and returns you a TclObject class object, which you can further typecast into your specific object type and use. - Prashant Shafiq Hashmi wrote: > Hello all, > > Is it possible to access an object of Agent/RCAgent, created in Tcl, from > another C++ class. > > Can anybody tell me ? > > Thanx > Shafiq > >

[ns] Error: Modifying IP for IPv6
I tried emulating ip in ns2 to create ipv6, just to increase header size to

reflect
ipv6 i.e append v6 to places where ip are.

[ns] Determine IP packet size
How can I know the packet size with TCl during runtime. I mean , like making it reflect in my trace file. Also, I want to be able to set a default size for my packet size at compile time in tcl. i was also wondering where in the C++ code, the packet size was initialize, I tried checking the /ns-2.28/tcl/lib/ns-default.tcl file but it's not there.

[ns] Event Scheduler in NS
Hello all
Below is a part of code which describes my problem. In the first function
"wakeupTimer()", i create an event. The event should call another function
"retryQuery()", after a timeout of 5 seconds from which the event is called.
But for me while i execute the ns code, and if i start my simulation at 0
seconds the event retryQuery() function should have been called after 5
seconds naturally, but actually it is calling immediately i.e at "0" seconds
itself. Is the code that i have written wrong.
wakeupTimer(int id) {
Scheduler &s = Scheduler::instance();
timeout = Scheduler::instance().clock() + 5;
Event *point_e = (Event *)retryQuery(id,nbIteration);
if (point_e!=NULL)
s.schedule((Handler *)this, point_e, timeout) ;
}
Event *dns_resolverAgent::retryQuery(int id,int nb_iteration){
wakeupTimer(int id);
}
