实际的标准文档可能不是最有用的。大多数编译器并没有完全实现这些标准，有时甚至会发生冲突。所以你已经有的编译器文档会更有用。此外，文档将包含特定于平台的注释和任何注意事项。

C-201x草案是N1336, c++ 0x草案是N3225。

虽然不是一个实际的标准，但ISO C (C89/90)有一个修正案，称为C94/95，或规范附录1。它被集成到C99中，尽管Clang等编译器允许您在命令行上指定-std=c94。ISO/IEC 9899:1990/Amd 1:1995可以从SAI GLOBAL以高价购买(PDF或硬拷贝)。

该文件的摘要可以在这里找到。

When the (then draft) ANSI C Standard was being considered for adoption of an International Standard in 1990, there were several objections because it didn't address internationalization issues. Because the Standard had already been several years in the making, it was agreed that a few changes would be made to provide the basis (for example, the functions in subclause 7.10.7 were added), and work would be carried out separately to provide proper internationalization of the Standard. This work has culminated in Normative Addendum 1. Normative Addendum 1 embodies C's reaction to both the limitations and promises of international character sets. Digraphs and the header were meant to improve the appearance of C programs written in national variants of ISO 646 without, e.g., { or } characters. On the other end of the spectrum, the facilities connected to and extend the old Standard's barely adequate basis into a complete and consistent set of utilities for handling wide characters and multibyte strings. This document summarizes Normative Addendum 1. It is intended to quickly inform readers who are already familiar with the Standard; it does not, and cannot, introduce the complex subject matter behind NA1, nor can it replace the original document as a reference manual. (Nevertheless, it tries to be as accurate as possible, and its author would like to hear about any errors or omissions.)
