Tell difference between Vista and XP [C]

Question

Is their a way in C to diferentiate between Vista and XP. Reason being is the the path I use is different in both.

Answer 1

You can get the version of your Windows OS by calling GetVersionEx .

OSVERSIONINFO vi;
vi.dwOSVersionInfoSize = sizeof vi;
GetVersionEx(&vi);

if (vi.dwMajorVersion >= 6)
    // Windows Vista or newer
else
    // Windows XP or older

Answer 2

You shouldn't have platform specific paths hard-coded into your application. There are environment variables for these things.

Open up a command prompt and type "set" to view a list of them. Several of these have been standard since Windows 95. Important environment variables to note are...

• HOME
• APPDATA
• ProgramFiles
• SystemRoot
• ALLUSERSPROFILE

So for example...

char * path;
    path = getenv("HOME");
    printf(path);

Have a poke around your target versions of windows to see what variables are common between the two.

edit: python has made me lazy with string manipulation, fixed example code.
