获取指定路径有三个函数，分别是：
SHGetSpecialFolderPathA(HWND hwnd, LPSTR pszPath, int csidl, BOOL fCreate) BOOL;【已不再支持】
SHGetFolderPathA(HWND hwnd, int csidl, HANDLE hToken, DWORD dwFlags, LPSTR pszPath) BOOL;【已丢弃】
SHGetKnownFolderPath(REFKNOWNFOLDERID rfid, DWORD dwFlags, HANDLE hToken, PWSTR *ppszPath) BOOL;
前两个函数使用CSIDL 来识别系统路径，SHGetKnownFolderPath 则使用CSIDL转化后的KNOWNFOLDERID标志来识别系统目录。
pszPath：返回路径的缓冲区
nFolder：标识代号
fCreate：true ：如果文件夹不存在则创建，false：不创建
dwFlags: 附加的获取选项。默认为0，其它更多
Folder Flag
hToken: 代表特定用户的access token.
