in case of gen_event call relavent handle_call is
called.
gen_event:call(EntMgr, Handler, Req) --> 				
M:handle_event(Req, S)

here Handler = {M, Id} 
Id can be anatom (i.e) Name of the event?

How does this Handler is passed to this callback
function handle_event
(i.e how does an event with {M, Id } is called)

Thanking u
