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

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!
