So it's related to Gnome and KDE, doesn't it ?

Doesn't exist a kernel function for doing that ?

No, but glib (gutils.c) implement multiplatform version of g_get_user_config_dir, g_get_user_data_dir and g_get_user_cache_dir
http://library.gnome.org/devel/glib/unstable/glib-Miscellaneous-Utility-Functions.html#g-get-user-config-dir

Here's an example of how I do this in Werewolf. It may be worthwhile modifying CPath to include a variation of my function. It's a pretty common and accepted way to handle user data on both platforms:

/// Retrieve the platform specific user data directory.
std::string getUserDataDirectory(std::string appName)
{
    std::string userAppDir;
#if defined(NL_OS_WINDOWS)
    // User data directory for Windows looks something like:
    // C:\Documents and Settings\myuser\Application Data\ApplicationName
    TCHAR szAPpData[MAX_PATH];
    SHGetFolderPath(NULL, CSIDL_PERSONAL, NULL, 0 szAppData);
    userAppDir.assign(szAppData);
    userAppDir += "\\";
    userAppDir += appName;
#elif defined(NL_OS_MAC)
    // User data directory for Mac OSX looks something like:
    // ~/Library/Application Support/ApplicationName
    userAppDir = getenv("HOME");
    userAppDir += "/Library/Application Support/";
    userAppDir += appName;
#else // NL_OS_WINDOWS
    // User data directory for Linux looks something like:
    // ~/.ApplicationName
    userAppDir = getenv("HOME");
    userAppDir += "/.";
    userAppDir += appName;
#endif // NL_OS_WINDOWS
    return userAppDir;
}

Note: This is basically not tested, I only have used the Linux variation of this function. But it illustrates the essential idea.

My config path for Debian's Snowball package. Code is based on glib2.0(they have multithred and lazy load support).
