Re: [ns] Timers Constructor??????

["Neeraj Poojary" <legolas_3@hotmail.com>]

MyTimer Timer_Instance;  // merely declares data of type MyTimer.
                         // ok inside a struct or class definition.
                         // e.g the definition of MyAgent in tcp.h

// Before you use the Timer_Instance, you need to instantiate it with
// the correct call to its constructor. hence you need to call the
// following in the constructor of MyAgent (in tcp.cc):

Timer_Instance(this);

// hope this answers your question.
