Linux系统中,设备驱动程序是操作系统内核的重要组成部分,在 与硬件设备之间 建立了标准的抽象接口。通过这个接口,用户可以像处理普通文件一样,对硬件设 备进行打开(open)、关闭(close)、读写(read/write)等操作。通过分析和设计设 备驱动程序,可以深入理解Linux系统和进行系统开发

本源代码所设计的文件系统,具有建立文件(create)、打开文件(open)、读文件(read)、写文件(write)、关闭文件(close)、撤销文件(delete)等功能。在模拟程序中可从键盘上输入文件操作命令来模拟各用户程序中所调用的各种文件操作,用一个结束命令(end)停止程序的执行。

//在tc3.0++在运行 //a数组用于随机产生1-6数表示每个方格后面的图形.用inita()函数来实现 //c数组用于记录方格的状态,用字符L(lock)表示没有打开的方格 //D(delete)表示已消去的方格.O(open)表示打开的方格. //变量m表示按回车键的有效次数.也是记忆力参数,越小记忆力越好 //变量xpos,ypos用于表示当前光标所在的位置 //(x1,y1),(x2,y2)用于记录打开的两个方格的位置 //judge()函数用于控制光标范围,使其不能移出长方形 //win()函数用于判断游戏是否过关,通过判断每个方格是否全是 D 状态 //xago,yago 用于记录移动前的位置 //ax,ay表示行列式的行与列,用它们来控制游戏的关数,ax位于3-6之间,ay位于4-7之间 //z来控制方格后的图形 //第一关后面的图形用1-6代表的图形.第二关后面的图形用0-9十个数。第三关后面的图形用A-O十五个字母, //第四关后面的图形用A-T二十一个字母

The J2000 codec was written in an effort to produce the cleanest and simplest implementation possible of the JPEG-2000 standard. We have put a particular emphasis on good architecture design and code simplicity, while at the same time providing an implementation as complete and efficient as possible. The source code for the codec is freely available for anyone to study or even for use in commercial programs. We hope that our open development process and our focus on clean, straightforward code will help make the J2000 codec become a reference implementation of the JPEG-2000 standard

JavaTV Program source code Need to play Windows Media files and streams, mpeg4 video or DVDs in java? Access WDM capture devices? Control a firewire DVCam? Then maybe this can help you. dsj is an ongoing project to provide a java wrapper around Microsoft s DirectShow API. It offers a set of high level classes that give java easy access to functionality widely missed by java programmers and also lets you dive deeper into the interiors of Windows core api for 2D media. On the java side dsj tries to keep things open as possible - you may use it standalone or let it feed data into JMF or other APIs.

pop3代理服务器源代码One of the most powerful features of Pop3 Agent is a naive Bayes filter, that is capable of recognizing spam e-mails after appropriate training. Pop3 Agent uses an embedded Firebird database server. Of course, you can configure Pop3 Agent to work with an existing server if there is another Interbase/Firebird installation available in your network. open the Pop3 Agent home directory, delete or rename gds32.dll and ib_util.dll, and set the INI file parameter FBembedded=0.
