winapi - Win32 函数获取 C :\ProgramData 的路径

Question

我的应用程序需要安装一些可以在运行时由应用程序编辑的文件。 Install shield 提供了一个别名 [CommonAppDataFolder]，它将在 Vista 和 Windows 7 上解析为 c:\programData，并且也适用于 Windows XP。是否有返回类似路径的 win32 函数？

也许我需要根据操作系统调用不同的函数？

SHGetFolderPath /SHGetSpecialFolderPath让你知道，用 CSIDL_COMMON_APPDATA争论。
请参阅此处的代码片段(底部):How to write a Windows XP Application that stores user and application data in the correct location by using Visual C++ ;原始链接不再有效 - 代码片段在下方):

include <shlwapi.h>
#pragma comment(lib,"shlwapi.lib")
void CreateTemporaryFile()
{
   TCHAR szPath[MAX_PATH];
   // Get path for each computer, non-user specific and non-roaming data.
   if ( SUCCEEDED( SHGetFolderPath( NULL, CSIDL_COMMON_APPDATA, 
                                    NULL, 0, szPath ) ) )
   {
      TCHAR szTempFileName[MAX_PATH];
      // Append product-specific path - this path needs to already exist
      // for GetTempFileName to succeed.
      PathAppend( szPath, _T("\\My Company\\My Product\\1.0\\") );
      // Generate a temporary file name within this folder.
      if (GetTempFileName( szPath, 
                           _T("PRE"),
                           0,
                           szTempFileName ) != 0 )
      {
         HANDLE hFile = NULL;
         // Open the file.
         if (( hFile = CreateFile( szTempFileName, 
                                   GENERIC_WRITE, 
                                   0, 
                                   NULL, 
                                   CREATE_ALWAYS, 
                                   FILE_ATTRIBUTE_NORMAL, 
                                   NULL )) != INVALID_HANDLE_VALUE )
         {
            // Write temporary data (code omitted).
            CloseHandle( hFile );
         }
      }
      else
          DWORD err = GetLastError();
   }
}

Windows XP:C:\Documents and Settings\All Users\Application Data

Windows Vista:C:\ProgramData

Windows 7:C:\ProgramData
