一本非常不错的linux书！

包含两个程序，一个用于读管道，一个用于写管道．主要是练习有名管道的使用方法．-contains two procedures, a pipeline used for reading, writing for a pipeline. Main pipeline is a well-known practice of use.

FFmpeg是用于录制、转换和流化音频和视频的完整解决方案， 包括 libavcodec ，一套领先的音/视频编解码类库。FFmpeg 在Linux上开发，当可以在大多数操作系统下编译，包括Windows。-FFmpeg is used to record, convert and stream audio and video of the complete solution, including libavcodec, a leading audio/video codec library. FFmpeg developed in Linux, as can be compiled under most operating systems, including Windows.

linux 下的ping源码，用socket实现，刚学linuxs socket编程的可以下载阅读。当然，你可以把该程序移植到嵌入式系统中。-ping source code under linux, using socket implementation, just learning linuxs socket programming can be downloaded to read. Of course, you can put this program ported to an embedded system.

linux下的dll控制编程-dll under the control programming

linux下著名的FreeBSD认证服务器，学习linux的不错的资料！-FreeBSD under the well-known linux authentication server, learn linux for good information!

本次实验的目的在于将nachos中的锁机制和条件变量的实现补充完整，并利用这些同步机制实现几个基础工具类。实验内容分三部分：实现锁机制和条件变量，并利用这些同步机制将实验一中所实现双向有序链表类修改成线程安全的；实现一个线程安全的表结构；实现一个大小受限的缓冲区（详细内容请看nachos-labs.pdf）。-the purpose of the experiment is to the nachos lock mechanism and conditions for the realization of supplementary variables integrity, Using these synchronization mechanism based tool for achieving several categories. Experiment three parts : achieving lock mechanism and variable conditions, Using these experimental synchronization mechanism as a bidirectional orderly objectlist revise the security thread; the realization of a security thread table structure; the realization of a limited size of the buffer zone (for details, please see nachos- labs.pdf).

系统调用拷贝函数 本程序通过Linux的系统调用进行文件拷贝，如果进行一定的修改可以支持断点续传-System call function copy of the procedures adopted by Linux system calls to file copy, if changes must support HTTP
