Erlang并发编程：消息传递与进程管理技术详解

Erlang是一种函数式编程语言，以其强大的并发处理能力而闻名。其独特之处在于轻量级进程的创建与消息传递机制。通过Erlang的并发模型，可以实现高度可靠、高度并发的分布式系统。

-module(message_passing).
-export([start/0, worker/1]).

start() ->
    Pid = spawn(?MODULE, worker, [hello]),
    Pid ! {self(), start_work},
    receive
        {Pid, Message} ->
            io:format("Received message: ~p~n", [Message])
    end,
    Pid ! {self(), stop_work}.

worker(Message) ->
    receive
        {From, start_work} ->
            io:format("Worker received start message from ~p~n", [From]),
            From ! {self(), Message},
            worker(Message);
        {From, stop_work} ->
            io:format("Worker received stop message from ~p~n", [From])
    end.
