Is the proper way of shutting down the emulator cleanly with an exit code the following? 1> F = fun(N) -> init:stop(), erlang:halt(N) end. #Fun<erl_eval.20.102880425> 2> F(100). ~~>echo $? 100 Is it guaranteed that the erlang:halt/1 call will be executed before the emulator exits as a result of the init:stop() call?
