c99

The C99 language introduces a number of new features that are of potential interest to software developers .

C99语言引入了许多可能会引起软件开发人员兴趣的新特性。

In particular , / / comments and mixed declarations and code have become standard features of C99 .

具体来说，//注释、混合声明和混合代码已经成为C99的标准特性。

However , many of the C99 features are now sufficiently widespread that new development projects can reasonably take advantage of them .

不过，很多C99特性现在已经足够普及，因而新的开发项目可以适当地利用它们。

The current ISO C99 ( the default standard that GCC uses and that this article assumes )

当前的ISOC99（这是GCC使用的默认标准，本文也假设采用这种标准）

Some of the most convenient features added in C99 are in the printf family of functions .

C99中增加的最方便的特性在printf函数家族中。

This concept is similar to the flexible array member in ISO C99 , but it uses a different syntax .

这个概念与ISOC99中灵活的数组成员相似，但是使用不同的语法。

This article reviews the availability of C99 language and library features on recent releases of Linux and BSD .

本文回顾了近来发布的Linux和BSD上的C99语言和库特性的可用性。

Floats in particular deviate from the C99 standard .

float来自于C99标准。

C99 introduced a qualifier , restrict , which can give a compiler optimization hints about pointers .

C99引入了一个限定词restrict，它可以向编译器给出关于指针的优化提示。

A lot of the library features added in C99 were based on existing practice , especially practices found in the BSD and Linux communities .

基于现有的实践，尤其是来源于BSD和Linux社区的实践，C99中增加了很多库特性。

The strftime () function has been extended in C99 to provide a few more commonly desired formatting characters .

C99中对strftime（）函数进行了扩展，以提供更多常用的格式化字符。

So we are actually using the C99 version of C , which really means nothing useful today other than to realize we are using that version .

所以我们在使用的C语言的C99版本，这对今天来说是没多大用处的，只是告诉我们使用的是那个版本而已。

If you specify a standard older than the ISO C99 version , some of the extensions described in this article may be disabled .

如果指定比ISOC99版本旧的标准，那么可能无法使用本文描述的一些扩展。

The standard that is a lot more explicit about locales is the so-called C99 standard , the most recent ISO standard applying to the C programming language .

所谓的C99标准对locale系统进行了更明确的说明，该标准是关于C编程语言的最新ISO标准。

If you 're using gcc , you should always use the static keyword on inline functions if you want the same behavior as C99 would give for the code .

如果您正在使用gcc，而且如果您期望代码有与C99相同的行为，您应该记住在内联函数前使用static关键字。

As a result , while simple code using variable-length arrays will work , a lot of code will run into the differences between the older GNU C support for VLAs and the C99 definition .

结果，虽然使用变长数组的简单代码将可以工作，但是大量的代码会遇到旧的GNUC对VLA的支持与C99定义之间在在差异的麻烦。
