调用Lua函数
这是Lua脚本语言教程系列之二。在第一篇中，我们学习了在Windows和Linux下编译并运行"Hello, World!"程序。如果你没有看过，请参考Lua入门一文。
本教程涵盖了Lua5.1。在Lua的每一个版本中都有一些非常不同之处。下面的示例代码将不能在老版本的Lua下运行。如果你仍然在使用老版本而且不愿意升级，不用担心，我已经在文章底部提供了4.0和5.0教程的源代码下载连接。好了，让我们开始吧！
这篇文章将教你如何在Lua中定义一个函数，然后在C/C++程序中调用它。同时，我们将学习到参数传递，返回值，以及处理全局变量。
你的第一个Lua函数
在Lua中定义函数是相当简单的。Lua函数以关键字"function"开头，后面跟随函数名，然后是参数列表。函数定义以关键字"end"结束。Lua函数能够接受多个参数，而且可以返回多个参数。
下面是一个实现两个数相加并返回

Lua入门
Lua是一个被设计成用于扩展C/C++编程的轻量级脚本语言。不幸的是，网上很少有关于这个语言的在线教程。我主要通过阅读其源代码来了解它是怎样工作并且通过一些发布的程序学习它。希望，通过下面的教程，会让学习Lua更加简单。
本教程涵盖了Lua5.1。在Lua的每一个版本中都有一些非常不同之处。下面的示例代码将不能在老版本的Lua下运行。如果你仍然在使用老版本而且不愿意升级，不用担心，我已经在文章底部提供了4.0和5.0教程的源代码下载连接。好了，让我们开始吧！
首先，你需要下载Lua。你需要从Lua下载页面去下载源代码。如果你需要编译好了的二进制库，你能在LuaBinaries 中找到你想要的库(lib or dll)。
现在，我们需要安装Lua。在Linux下，你应该先解压文件，然后以root用户在命令行键入"make linux"和"make linux install"。如果你需要帮助

Writing Scalable Applications for Windows NT

John Vert
Windows NT Base Group
Revision 1.0: June 6, 19951. Introduction
One of the major goals of Microsoft® Windows NT™ is to provide a robust, scalable symmetric multiprocessing (SMP) operating system. By harnessing the power of multiple processors, SMP can deliver a large boost to the performance and capacity of both workstation and server applications. Scalable SMP client-server systems can be very effective platform

Writing Windows NT Server Applications in MFC Using I/O Completion Ports

李津 — Wed, 24 Jun 2009 17:39:00 +0800

AbstractOne of the most frequently encountered challenges in writing server applications is the multiple-client bottleneck: How to service multiple clients simultaneously without degrading overall performance. This article discusses two possible solutions to this problem: First, I demonstrate how each client can be associated with one dedicated server thread, and then I discuss input/output (I/O) completion ports, an I/O system extension in Microsoft® Windows NT® that allows asynchronous I

Windows Sockets 2.0: Write Scalable Winsock Apps Using Completion Ports

李津 — Wed, 24 Jun 2009 17:35:00 +0800

SUMMARYWriting a network-aware application isn't difficult, but writing one that is scalable can be challenging. Overlapped I/O using completion ports provides true scalability on Windows NT and Windows 2000. Completion ports and Windows Sockets 2.0 can be used to design applications that will scale to thousands of connections. The article begins with a discussion of the implementation of a scalable server, discusses handling low-resource, high-demand conditions, and addre
