C语言 有没有类似官方 C 文档的东西？

Is there something like the official C documentation?

提问by Auron

I'm looking for the documentation of all the syntax and built-in functions in C, but I can't find any site online which seems like an ultimate official source of standard C knowledge.

我正在寻找 C 语言中所有语法和内置函数的文档，但我在网上找不到任何网站，这似乎是标准 C 知识的最终官方来源。

Apart from the famous book by Kernighan and Ritchie, isn't there any online C specification? Maybe there is, and I don't know how to find it. Or maybe the problem is that I don't exactly know what I'm looking for.

除了Kernighan 和 Ritchie 的那本著名的书之外，没有任何在线 C 规范吗？也许有，我不知道如何找到它。或者也许问题是我不完全知道我在寻找什么。

You can obtain a PDF copy of the C99 standard (ISO/IEC 9899:1999) from ANSI (and other fine standards organizations) for your private use for a modest fee - I believe it was 18 USD when I bought mine. Having that available is invaluable to me. But if you find a copy in public, then it is contraband.

您可以以适度的费用从 ANSI（和其他优秀的标准组织）获得 C99 标准（ISO/IEC 9899:1999）的 PDF 副本供您私人使用——我相信我买的时候是 18 美元。拥有它对我来说是无价的。但如果你在公共场合找到了一份副本，那么它就是违禁品。

You can find final committee drafts and current working documents of the C (C0x) Standard Committee at the JTC1, SC22, WG14 web site at the Open Standards Organization. (That's Joint Technical Committee 1, Sub-Committee 22, Working Group 14, I believe).

您可以在开放标准组织的 JTC1、SC22、WG14 网站上找到 C (C0x) 标准委员会的最终委员会草案和当前工作文件。（我相信是第 1 联合技术委员会、第 22 分委员会、第 14 工作组）。

There is also a hardback book 'The C Standard: Incorporating Technical Corrigendum 1'(also including the Rationale) available for a slightly less modest 85 USD or thereabouts.

还有一本精装书“The C Standard: Incorporating Technical Corrigendum 1”（也包括基本原理），售价 85 美元左右。

One of the best books about C is 'C: A Reference Manual'in its fifth edition. However, you asked for 'ultimate official source of standard C knowledge', and the only 'official' such source is the C standard, plus its corrigenda.

关于 C 的最好的书之一是第五版的“C：参考手册”。但是，您要求提供“标准 C 知识的最终官方来源”，而唯一的“官方”此类来源是 C 标准及其勘误表。

The official C99 standard is available for purchase from your national standards body; however, in practice everyone reads the draft with post-1999 corrections/amendments included, which you can download for free:

官方 C99 标准可从您的国家标准机构购买；然而，实际上每个人都会阅读包含 1999 年后更正/修正的草稿，您可以免费下载：

Strictly speaking, the C standard is not available for free. You need to purchase an electronic copy from http://www.ansi.org/or http://www.iso.org.

严格来说，C 标准不是免费提供的。您需要从http://www.ansi.org/或http://www.iso.org购买电子副本。

However, you can download a free draft versionfrom the Open Standards Organization's website - this is as good as or better than the official standard itself. It incorporates information from the ISO C99 standard plus three Technical Corrigenda, all of which are official ISO documents.

但是，您可以从开放标准组织的网站下载免费的草案版本——这与官方标准本身一样好或更好。它包含来自 ISO C99 标准的信息和三个技术勘误表，所有这些都是官方 ISO 文件。

The most official documentation is the ISO standard, to which compilers are written and are expected to interpret correctly.

最官方的文档是 ISO 标准，编译器按照该标准编写并被期望正确解释。

C99 Standard

C99标准

Here's the latest Committee draft on the C99 Standard, last updated April 12, 2011:

这是关于 C99 标准的最新委员会草案，最后更新于 2011 年 4 月 12 日：

I'll try to keep it up to date with the latest version as I can.

我会尽量让它与最新版本保持同步。

Kernighan & Ritchie

克尼汉和里奇

I also found K&R's text, second edition, here: http://www.ime.usp.br/~pf/Kernighan-Ritchie/C-Programming-Ebook.pdf

我还在这里找到了 K&R 的文本，第二版：http: //www.ime.usp.br/~pf/Kernighan-Ritchie/C-Programming-Ebook.pdf

However, I'd use the -Wallflag when compiling the examples in the book so that you don't get led too far astray by the age of the text.

然而，我会-Wall在编译书中的例子时使用这个标志，这样你就不会被文本的年龄误导得太远。

If what you want is the documentation for the standard library functions, then P.J. Plauger's "The Standard C Library" http://www.amazon.com/Standard-C-Library-P-J-Plauger/dp/0131315099/ref=sr_1_1?s=books&ie=UTF8&qid=1290273108&sr=1-1is the best reference. It's got pretty extensive annotation and comentary on the why and how of the standard.

如果您想要的是标准库函数的文档，那么 PJ Plauger 的“标准 C 库” http://www.amazon.com/Standard-C-Library-PJ-Plauger/dp/0131315099/ref=sr_1_1? s=books&ie=UTF8&qid=1290273108&sr=1-1是最好的参考。它对标准的原因和方式有相当广泛的注释和评论。
