Hi, I have currently the following erlang code



Code:
-define(tag, normal).

normal(_Self, Data) ->
         someUnit_signal:send(?tag, fun(_) -> {?tag, Data} end).

waitfor() ->
    {ok, {_, Data}} = someUnit_signal:wait(?tag,
                                    fun({?tag, _}) -> true end,10000), Data.



I want to convert this so that I don't use the class
someUnit_signal, I just want to do a bang between this functions. This is how far I've got

Code:
-define(tag, normal).
normal(Self, Data) ->
Self ! {Data}.

waitfor()->
receive
????
after 10000->{timeout}
end.


I am currently lost on what to write in the receive case, I just want the function to wait some time(10000 ms) and send back the Data variable that the function normal receives. So if anybody could fill in this case I would be very greatful
