Erlang并发编程示例与进程间通信技巧分享

Erlang 是一种功能强大的并发编程语言，其独特之处在于轻松处理并发任务并实现高度可靠的系统。通过进程间消息传递和轻量级进程管理，Erlang 提供了一种优雅的方式来构建并发应用程序。

-module(example).
-export([start/0, ping/2, pong/0]).

start() ->
    PongPid = spawn(example, pong, []),
    spawn(example, ping, [PongPid, 0]).

ping(PongPid, Count) ->
    PongPid ! {self(), increment},
    receive
        pong ->
            io:format("Ping received pong~n"),
            NewCount = Count + 1,
            ping(PongPid, NewCount);
        {pong, NewPongPid} ->
            io:format("Ping received pong from new process~n"),
            NewCount = Count + 1,
            ping(NewPongPid, NewCount)
    end.

pong() ->
    receive
        {From, increment} ->
            io:format("Pong received ping~n"),
            From ! pong,
            pong()
    end.
