About the Handler in gen_event

[Sean Hinde]

Each time one of your callbacks is called it should return a term where one
of the elements is the new state (look at the gen_event manual to find out
the possible return values. Next time any callback is called it will get
this new state.
 
To trace you can use the sys:trace/2 function - it is documented

Ulf Wiger and sean, 


I thank, According to the changes this module is working fine, 


I did not get the concept of the 'State' exactly  incase of  all the
callback functions, 


Any tips can help me more in working and debugging with callback modules  


regards
