-module(process2).
-compile(export_all).
-include("common.hrl").

%% Usage:

%% 结束服务：myserver ! stop.

start()->
    Pid = spawn(?MODULE, server, []),
    %% 给服务注册一个名字：myserver
    erlang:register(myserver, Pid).

server() ->
    receive
        Msg ->
            ?MODULE:handle(Msg),
            server()
    end.

handle(now) ->
    ?I("Current time is: ~p", [erlang:localtime()]);

handle(stop) ->
