This directory is unique per user, per application. + * + * This function will decide the appropriate location in the native filesystem, + * create the directory if necessary, and return a string of the absolute + * path to the directory in UTF-8 encoding. + * + * On Windows, the string might look like: + * "C:\\Users\\bob\\AppData\\Roaming\\My Company\\My Program Name\\" + * + * On Linux, the string might look like: + * "/home/bob/.local/share/My Program Name/" + * + * On Mac OS X, the string might look like: + * "/Users/bob/Library/Application Support/My Program Name/" + * + * (etc.) + * + * You specify the name of your organization (if it's not a real organization, + * your name or an Internet domain you own might do) and the name of your + * application. These should be untranslated proper names. + * + * Both the org and app strings may become part of a directory name, so + * please follow these rules: + * + * - Try to use the same org string (including case-sensitivity) for + * all your applications that use this function. + * - Always use a unique app string for each one, and make sure it never + * changes for an app once you've decided on it. + * - Unicode characters are legal, as long as it's UTF-8 encoded, but... + * - ...only use letters, numbers, and spaces. Avoid punctuation like + * "Game Name 2: Bad Guy's Revenge!" ... "Game Name 2" is sufficient. + * + * This returns an absolute path in UTF-8 encoding, and is guaranteed to + * end with a path separator ('\\' on Windows, '/' most other places). + * + * The pointer returned by this function is owned by you.
