Compile-time defines for Windows versions

NTDEV
1

Hello,

I have looked for some #define definitions to do the following, but can’t find anything. I may be missing the obvious. What I need is something like this:

#ifdef WINXP
(Windows XP specific code)
#endif
#ifdef WIN2K
(Windows 2000 specific code)
#endif

Are there defines like this, and if so, where?

Hi Barry,

You can use _WIN32_WINNT as the version indicator. It’s value is 0x400 for
Windows NT, 0x500 for 2K, 0x501 for XP.

Of course, you can do something like:

#define WINXP (_WIN32_WINNT >= 0x501)
#define WIN2K (_WIN32_WINNT == 0x500)

etc.

You can add #defines like these in the sources file using USER_C_FLAGS. Your source file will look like the following:

USER_C_FLAGS=$(USER_C_FLAGS) /DYOUR_DEFINE

SOURCES=

USER_C_FLAGS = $(USER_C_FLAGS)

Then you can add
#ifdef YOUR_DEFINE
…
#endif
to your source code.

Regards,
Gregory
