图1-1 UNIX系统的体系结构 一大批提供了对系统的高级看法的应用子系统及应用程序,诸如shell、编辑程序、SCCS(source code control system)及文档准备程序包等,都逐渐变成了“UNIX系统”这一名称的同义语。然而,它们最终都使用由内核提供的低层服务,并通过系统调用的集合来利用这些服务。系统Ⅴ中大约有64个系统调用,...
实际的U N I X操作系统源代码的名称是“UNIX Operating System Source Code ”,它在1 9 7 6年7月 第一次印刷。这是对我们在 1 9 7 5年1 2月收到的UNIX 版本6代码进行特殊编辑处理后构成的。 在 1 9 7 6年,本分析的原始版本首先以复写方式散发,这一年的后期, n r o f f文本格式化程序开 发...

This chapter describes how you can modify the source code for your UNIX application so that it will compile on the Microsoft® Windows® operating system. You need to modify your code due to the differences between the UNIX and Windows application and coding environments described earlier in ...
This chapter describes how to modify UNIX source code to compile on Interix.Because Interix is designed to be similar to UNIX, few changes are needed to recompile code under Interix. However, there are differences between Interix and UNIX, which mainly arise from the underlying differences in ...
2. Linux Linux is a free and open-source Unix-like operating system, which is based on the POSIX and UNIX standards. It supports multi-user, multi-threading, and multi-CPU capabilities. The primary uses of Linux are servers, especially network servers, and it currently has two ...
21 to include the settings for your system. Also, you'll probably need to 22 modify the source code to get it to build on a different operating system. 23 The example source was compiled and tested using FreeBSD 5.2.1, Linux 2.4.22, ...
First, anyone can learn from it. In fact, Linux was born out of a desire to learn and experiment with Unix. Linus Torvalds wanted a copy of Minix to study and modify, but its developers did not want to hand out its source code. In response, Torvalds simply made his own Unix kernel,...
However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself ...
