你能在保护模式下切换到C吗？ [英] Can you switch to C in protected mode?

问题描述

我正在做一个宠物项目。我在DOS中开始组装，切换到

保护模式并在该环境中玩游戏。我是b / b
想知道我是否从C程序中的main开始然后调用程序集

的东西切换到pmode如果我可以使用一些C'的函数在

pmode？

谢谢

你的问题是完全的在这里偏离主题。请在新闻组中询问

尝试回答你自己的问题：（二进制）代码写的

是否为非保护汇编语言中的模式通常在保护模式和非保护模式下都保持不变

？我对此表示怀疑。并且

如果它的工作没有变化，你为什么要关心你的模式是什么？

我不同意，我认为这是相关的。我问的是C的内部因为我没有特别提及printf或fopen并不意味着它不是关于C.

I have a pet project I''m working on. I start in DOS in assembly, switch to
protected mode and play around with things in that environment. I''m
wondering if i started at main in a C program then called the assembly
stuff to switch to pmode if i could then use some of C''s functions in
pmode?
Thanks

The terms "DOS", "assembly", "protected mode" and "pmode" are not
defined in C. They''re specific to a certain operating system, not to
programming languages.
Your question is completely off-topic here. Please ask in a newsgroup
dedicated to your own operating system (MS-DOS?).

Most reasonable operating systems start in "protected mode", if the
CPU in question has one, and you never get to execute code outside
of it.

Try answering your own question: does the (binary) code written
for non-protected-mode in assembly language generally work unchanged
in both protected mode and non-protected mode? I doubt it. And
if it DOES work unchanged, why would you care which mode you are
in?

I disagree, i think it is relevant. I''m asking about the internals of C
Just because i didn''t specifically mention printf or fopen doesn''t mean its
not about C.
