为什么Windows中没有C ++？ [英] Why no C++ in Windows itself?
问题描述
现在很长一段时间我正在使用Dependency Walker for Win32。并且
在System32中导航不同的Dll。找到我的目标API的文件夹
函数。我注意到的是，''几乎''所有系统.dll和
..exe
文件是用C而不是C ++编写的。如果C ++是一种功能强大的OO语言并且它比大型应用程序开发的C大得多，那么为什么微软在它的操作系统中使用了它？ ？这是否存在兼容性问题
我不知道？或其他什么？

你怎么知道它们是用C语写的？您是否检查了
汇编程序以查找是否存在C ++启动代码（例如运行全局对象构造函数的
）？请记住，C ++代码不需要动态地链接到C ++运行库，并且它不需要向外界提供C ++
接口。

GDI系统至少用C ++编写。

我不知道你对C ++的看法，但在最早的定义中，C ++被称为C with classes。所以如果那里没有课，那就没有C ++
代码;它只是纯粹的C ....
PS：依赖性walker（版本2.1.36668）能够在他们的C ++中显示他们的类中的函数。看看你是否有VS.NET 2003

It is a long time now that I am using "Dependency Walker for Win32" and
navigating through different Dlls in "System32" folder to find my target API
functions. The thing I have noticed is that, ''almost'' all system .dll and
..exe
files are written in C and not C++. If C++ is a powerful OO language and
it''s much greater than C for large application development, then why haven''t
Microsoft used it in its operating system? Is there a compatibility issue
here that I am not aware of? Or something else?

How can you tell that they are written in C? Have you examined the
assembler to look for the presence of C++ startup code (such as the
running of global object constructors)? Remember that C++ code need not
dynamically link with the C++ runtime, and it need not present a C++
interface to the outside world.

The GDI system is written in C++, at least.

I don''t know what you think of C++, but in its earliest definition, C++ was
called "C with classes". So if there is no class in there, there is no C++
code; it is just pure C....
PS: dependency walker (version 2.1.36668) is able to show functions inside
their classes if their are C++. Take a look if you have VS.NET 2003
