[ns] SCHEDULERS???

[Anis Koubaa]

Hi Ns users ;
I want to know the meaning of  following statements and the différence
between them :
/*******************************************************/
Scheduler::instance().schedule(Handle h, Event* e, double delay);
Scheduler::instance().reschedule(Handle h, Event* e, double delay);
/***********************************************************************/
The Handle , and Event what do they do?
Thak You
