blocks|key|2212117|text|在C语言中，做事情的方式完全相同，但语言对它的支持却不那么明显。不是创建一个类来封装某种状态，而是创建一个结构。不使用隐式参数创建类成员，而是创建函数，显式传递一个struct*作为第一个参数，然后对结构进行操作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2212118|为了确保封装不中断，您可以在头中声明结构，但只能在使用它的.c文件中定义它。虚拟函数需要更多的工作--但这只是在结构中放置函数指针的情况。在C中，这实际上比C%2B%2B更方便，因为在C中，您可以手动填写vtable，对代码的哪一部分实现什么COM接口的部分(当然是C中的COM+)有相当好的控制。|2212119|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Things are done exactly the same way in C, but with less overt support from the language. Instead of creating a class to encapsulate some state, you create a struct. Instead of creating class members, with implicit this parameters, you create functions that you explicitly pass a struct* as the first parameter, that then operate on the struct.

To ensure that encapsulation is not broken you can declare the struct in a header, but only define it in the .c file where it is used. Virtual functions require more work - but again, its just a case of putting function pointers in the struct. Which is actually more convenient in C than C++ because in C you get to fill in your vtables manually, getting quite a fine level of control over which part of code implements part of what COM interface (if you are into COM in C of course).

blocks|key|2212143|text|您可能会发现ccan+(模仿Perl的CPAN)的综合C存档网络很有趣。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2212144|目前它虽小，但其贡献是高质量的。许多贡献都是由linux内核开发人员做出的。|2212145|几乎所有的东西都属于“几千LOC”或更少的类别。|2212146|entityMap|0|LINK|mutability|MUTABLE|url|http://ccan.ozlabs.org/^0|6|4|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]]]

You might find the <a href="http://ccan.ozlabs.org/" rel="nofollow">ccan</a> (Comprehensive C Archive Network, modeled after Perl's CPAN) interesting.

It's small at the moment, but the contributions are of high quality. Many of the contributions are by linux kernel developers.

Almost everything in there falls into the "few thousand LOC" or less category, too.

blocks|key|2212170|text|如果您想要一个小示例，请尝试查看基本Linux实用程序的源代码。GNU二进制、制作或任何其他GNU实用程序都有可用的完整源代码，并且代码基数相对较小(有些代码比其他代码大)。最简单的事情通常是从您以前使用过并且已经熟悉的实用程序开始。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2212171|entityMap|0|LINK|mutability|MUTABLE|url|http://www.gnu.org/software/binutils/|1|http://www.gnu.org/software/make/|2|http://www.gnu.org/software/#allgnupkgs^0|W|6|0|13|2|1|18|9|2|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]|$A|T|B|U|1|V]|$A|W|B|X|1|Y]]|C|$]]|$1|D|3|-4|5|6|7|Z|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]|N|$5|G|H|I|C|$J|O]]]]

If you want a small example to start with, try looking at the source for the basic Linux CLI utilities. <a href="http://www.gnu.org/software/binutils/" rel="nofollow">GNU binutils</a>, <a href="http://www.gnu.org/software/make/" rel="nofollow">make</a>, or any of the <a href="http://www.gnu.org/software/#allgnupkgs" rel="nofollow">other GNU utilities</a> have full source code available and are relatively small code bases (some are larger than others). The easiest thing is usually to start with a utility that you have used before and are already familiar with.

Look at <a href="http://library.gnome.org/devel/glib/" rel="nofollow">GLib</a> for an almost canonical example of how to do object oriented programming in C.

I have been doing OOP (C++/Java/PHP/Ruby) for a long time and really have a hard time imagining how large programs and libraries such as Linux or Apache can be written entirely in an imperative style. What would be small open source C projects I could look at to get a feel of how things are done in C?

Bonus points if the project is hosted on GitHub.

Coming from an OOP background, what would be some C programs/libraries to help me get the "C way"?

我做OOP (C++/Java/PHP/Ruby)已经很长时间了，我真的很难想象像Linux或Apache这样的大型程序和库可以完全以命令式的方式编写。小型开源C项目是什么，我可以看看它是如何在C中完成的？如果项目托管在GitHub上，则奖励积分。

问来自OOP背景，什么是一些C程序/库来帮助我获得"C方式“？
