多进程共享函数通信 1.4

多线程与单线程的区别：

单线程顺序执行：ABCDEFG,HIJKLMN
单线程异步执行：ABC,KLMN,EFGHI，错开执行避免I/O之类的长时间等待卡住线程【WinWait】
多线程：一个进程内可有多个线程ABCDEFG同时执行互不干扰
多进程：创建多个进程ABCDEFG并互相通信，来达到仿多线程的效果。

 

支持编译后，自己调用自身实现多进程

20220714：修复错误并修改函数名称，与AHK_H 版本进行区分。可以更好的实现多进程+多线程

20220327：修复之前的版本ahkGetvar()无法获取变量内容的BUG，并给出解决方案

 　 　 　 　   　   　    　   多进程共享函数、连锁关闭并通信

                    关联进程变量 := New ExecProcess("标签名称") 新建关联进程, 可传参
                    关联进程变量 := ""         清空这个 "关联进程变量" 来关闭对应的进程

     语法参考AHK_H对线程控制的用法，并新增相互通信和进程间互相控制的功能。支持编译运行
  新进程默认隐藏托盘图标和禁用热键来避免冲突，恢复热键和控制的方法类库说明里的 F3 和 F4

    我是不是可以理解成，Global声明的全局变量，只在单个进程里有用？

    • dbgba

      对的，大致就是简易的操控其它进程。操控其它进程的方法是通过进程之间的通信在操作
