How to get the %AppData% folder in C?

Question

As above, how do I get the AppData folder in Windows using C?

I know that for C# you use Environment.SpecialFolder.ApplicationData

Answer 1

Use SHGetSpecialFolderPath with a CSIDL set to the desired folder (probably CSIDL_APPDATA or CSIDL_LOCAL_APPDATA).

You can also use the newer SHGetFolderPath() and SHGetKnownFolderPath() functions. There's also SHGetKnownFolderIDList() and if you like COM there's IKnownFolder::GetPath().

Answer 2

If I recall correctly it should just be

#include <stdlib.h>
getenv("APPDATA");

Edit: Just double-checked, works fine!
