问题描述

函数getenv()是否可以在所有Windows计算机上使用?

Will the function getenv() works in all windows machine?

推荐答案

getenv(..)来自stdlib.h，属于ANSI C标准函数.它可以在具有C运行时库的每个系统上运行，而不仅仅是在Windows计算机上.

有关该功能的Microsoft帮助页面(此处)指出它将工作于:Windows 95，Windows 98，Windows 98 Second Edition，Windows Millennium Edition，Windows NT 4.0，Windows 2000，Windows XP Home Edition，Windows XP Professional，Windows Server 2003 ..而且我敢肯定，他们只是忘了提及他们的较新的系统.

他们还提到不建议使用该函数，而应改用getenv_s.

希望对您有所帮助.

加油！

Hi,

getenv(..) comes from stdlib.h and belongs to the ANSI C standard functions. It will work on every system that has a C runtime library, not just on Windows machines.

The Microsoft help page about the function (here) states it will work on: Windows 95, Windows 98, Windows 98 Second Edition, Windows Millennium Edition, Windows NT 4.0, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 .. and I am pretty sure they just forgot to mention their newer systems.

They also mention that the function is deprecated and that getenv_s should be used instead.

I hope that helps.

Cheerio!
