工作原理 由于lua只能单线程运行,该lib要求所有lua代码在单线程,而多线程部分只能为c代码 具体用法上要求多线程部分必须用c实现 相关模块 线程池 异步函数实现框架 Now only a sleep function is provided Usage: function test2_threadpool() local tp = Dll.MyTHdPool() local function f() n = n+ print('f ' .. n) ) then return end tp:…

lua元表和元方法 <lua程序设计> 13章 读书笔记 lua中每个值都有一个元表,talble和userdata可以有各自独立的元表,而其它类型的值则共享其类型所属的单一元表.lua在创建table时不会创建元表. t = {} print(getmetatable(t)) --显示过元表 此时是nil --可以用setmetatable来设置或修改任何table的元表 t1 = {} setmetatable(t,t1) assert(getmetatable(t) == t1) 任何t…

昨天中国高校发生了一件骇人听闻的事情,听说不少高校的校园网用户连接校园网被勒索病毒给黑了,重要文件全部被加密,必须要支付赎金才能解密,具体新闻可以参见:http://www.sohu.com/a/140236495_346360.而且还有不少是和我一样的大四毕业狗,听说因为毕业论文没有备份,结果被黑了,然后,然后就没有然后了...真的是欲哭无泪啊.看到这个消息,我想起来我的没写完的毕业论文好像也没备份,吓得我赶紧去把论文备份到onedrive上面去了.据说微软之前已经打过补丁了,只是我国广大使用…

ok,前面准备给一个dll写wrapper,写了篇日志,看似写的比较明白了,但是其实有很多米有弄明白的.比如PIL中使用的element,key,tname,field这些,还是比较容易混淆的.今天正好搞搞清楚. 1.stack 这个应该不用多讲了,C和lua中的交互就是基于一个stack的,而且每次lua调用一个c函数,都是给分配一个新的stack.它的原型: typedef int (*lua_CFunction) (lua_State *L); stack中的基本单元在PIL中多成为ele…

Lua中的捕获   捕获 捕获是这样一种机制:可以使用模式串的一部分匹配目标串的一部分.将你想捕获的模式用圆括号括起来,就指定了一个捕获.在string.find使用捕获的时候,函数会返回捕获的值作为额外的结果.这常被用来将一个目标串拆分成多个: pair = "name = Anna"_, _, key, value = string.find(pair, "(%a+)%s*=%s*(%a+)")print(key, value)    --> name …
