Re: C and C++ don't mix, Something wrong with my header?

I'm trying to include some C functions from IOPort.h/cpp to my C++
program.. i placed the IOPort.h into stdafx, but when I try to
compile i get the errors like: ioport.h(8) : error C2065: 'UINT' :
undeclared identifier. So, the Visual Studio 2005 compiler doesn't
know what UNIT is?

Am I doing something wrong? I attached my code below.

I'd appreciate any help..

Thanks,
Soren

#ifndef _WIN32_WINNT // Allow use of features specific to Windows XP
