alloc(Pid) -> gen_server:call(?MODULE, {alloc, Pid}, infinity).

handle_call({alloc, Pid}, From, State) ->
    ... some logic to save caller information From..
    {noreply, State}.

and somwhere else in code

gen_server:reply(From, finally_my_answer_is_ready).


handle_call({alloc, Pid}, From, State) ->
    {reply, my_answer_is_allready_available, State}.

if you can answer immediately.
