问题 I'm trying to understand request order in erlang, but I can't seem to grasp it very well. Here's the example code: test() -> Server = start(), spawn(fun() -> write(Server, 2), io:format(”Child 1 read ~p~n”, [read(Server)]) end), write(Server, 3), write2(Server, 5), spawn(fun() -> write2(Server, 1), io:format(”Child 2 read ~p~n”, [read(Server)]) end), io:format(”Parent read ~p~n”, [read(Server)]). And here's the server: start() -> spawn(fun() -> init() end). init() -> loop(0). loop(N) ->
