Re: [ns] How to set random starting places within a trace file

[Ken Pounds <hemin99@chinaren.com>]

I found that in there is a random starting function in traffictrace.cc

/* pick a random starting place in the trace file */
	return (int(Random::uniform((double)nrec_)+.5));

whether it means I don't need to be worried about the randomnizing. And ns
will do it for me?
