terminating a gen_server is handled like this:

any one of the callback modules 3 handle_* functions (handle_call/3, 
handle_cast/2, handle_info/2) can return a tuple with the first member 
equal to stop (eg {stop,Reason,Reply,NewState} for handle_call/3).

The gen_server will then call Module:terminate(Reason,NewState) and 

does this answer your question?
