C++获得系统路径

源码：

#include <Shlobj.h>
#include <stdio.h>
#include <locale.h>

int main()
{
    setlocale(LC_ALL, "chs");

    TCHAR szPath[MAX_PATH];

    int CSIDL[] = {
        CSIDL_ADMINTOOLS,       CSIDL_APPDATA,  CSIDL_CDBURN_AREA,      CSIDL_COMMON_ADMINTOOLS,    CSIDL_COMMON_APPDATA,
        CSIDL_COMMON_DESKTOPDIRECTORY,          CSIDL_COMMON_DOCUMENTS, CSIDL_COMMON_FAVORITES,     CSIDL_COMMON_MUSIC,
        CSIDL_COMMON_PICTURES,  CSIDL_COMMON_PROGRAMS,  CSIDL_COMMON_STARTMENU, CSIDL_COMMON_STARTUP,
        CSIDL_COMMON_TEMPLATES, CSIDL_COMMON_VIDEO,     CSIDL_COOKIES,          CSIDL_FAVORITES,
        CSIDL_HISTORY,          CSIDL_INTERNET_CACHE,   CSIDL_LOCAL_APPDATA,    CSIDL_MYDOCUMENTS,
        CSIDL_MYMUSIC,          CSIDL_MYPICTURES,       CSIDL_MYVIDEO,          CSIDL_PROFILE,      CSIDL_PROGRAM_FILES,
        CSIDL_PROGRAM_FILES_COMMON,                     CSIDL_PROGRAMS,         CSIDL_RECENT,       CSIDL_SENDTO,
        CSIDL_STARTMENU,        CSIDL_STARTUP,          CSIDL_SYSTEM,           CSIDL_TEMPLATES,    CSIDL_WINDOWS,
        0
    };

    for (int i=0;CSIDL[i];i++) {
        if (SUCCEEDED(SHGetFolderPath(NULL, CSIDL[i], NULL, SHGFP_TYPE_CURRENT, szPath))) {
            wprintf(L"%d, %s
", i, szPath);
        }
    }

    return 0;
}

在XP上，用VS2010编译通过，假设是win7或者更高版本号，应该用

HRESULT SHGetKnownFolderPath(
  _In_      REFKNOWNFOLDERID rfid,
  _In_      DWORD dwFlags,
  _In_opt_  HANDLE hToken,
  _Out_     PWSTR *ppszPath
);

结果：
