[ns] Trace Time in Multicast

["yoon" <yby9650@ewha.ac.kr>]

Hi!!

Now..I simulate multicast related source using ns(DM.tcl) in Linux.

In inner node(maybe, routers), I want to forward data to child nodes in tree
after some processing..

Some processing is to execute .exe(crypto++) program which is outside of
ns...

So..I added code in "trace.cc" like this..

     TCL::instance().evalf("puts $f [exec /crypto41/cryptest.exe e in.dat
out.dat]")

I thought... after executing this code, there is some delays before
executing Scheduler::instance().clock()(receive time).

But ...This code did not affect simulation time..

How can i affect " exec function result" in simulation time???



( Also I used another method..
  In trace.cc,  I stored "exec" execution result value in another variable.

  And when print trace result, sprint( "%c "Timeformat".........
                                        ,
pt->round(Scheduler::instance().clock()),
                                          ----------------------------------
------
                                          change to like thie :
pt->round(Scheduler::instance().clock() + variable)

  but error....-_-;;

)

please help me!!!!!!
