c/c++ CopyFile，GetFileAttributes复制文件和更改文件属性

通过使用GetFileAttributes 或者GetFileAttributes函数能够获得文件的属性，CreateFile和SetFileAttributes函数可以设置文件的属性。

例子：

#include <windows.h>
#include <tchar.h>
#include <stdio.h>
#include <strsafe.h>

void _tmain(int argc, TCHAR* argv[])
{
   WIN32_FIND_DATA FileData;
   HANDLE          hSearch;
   DWORD           dwAttrs;
   TCHAR           szNewPath[MAX_PATH];   

   BOOL            fFinished = FALSE; 

   if(argc != 2)
   {
      _tprintf(TEXT("Usage: %s <dir>\n"), argv[0]);
      return;
   }

// Create a new directory. 

   if (!CreateDirectory(argv[1], NULL))
   {
      printf("CreateDirectory failed (%d)\n", GetLastError());
      return;
   } 

// Start searching for text files in the current directory. 

   hSearch = FindFirstFile(TEXT("*.txt"), &FileData);
   if (hSearch == INVALID_HANDLE_VALUE)
   {
      printf("No text files found.\n");
      return;
   } 

// Copy each .TXT file to the new directory
// and change it to read only, if not already. 

   while (!fFinished)
   {
      StringCchPrintf(szNewPath, sizeof(szNewPath)/sizeof(szNewPath[0]), TEXT("%s\\%s"), argv[1], FileData.cFileName);

      if (CopyFile(FileData.cFileName, szNewPath, FALSE))
      {
         dwAttrs = GetFileAttributes(FileData.cFileName);
         if (dwAttrs==INVALID_FILE_ATTRIBUTES) return; 

         if (!(dwAttrs & FILE_ATTRIBUTE_READONLY))
         {
            SetFileAttributes(szNewPath,
                dwAttrs | FILE_ATTRIBUTE_READONLY);
         }
      }
      else
      {
         printf("Could not copy file.\n");
         return;
      } 

      if (!FindNextFile(hSearch, &FileData))
      {
         if (GetLastError() == ERROR_NO_MORE_FILES)
         {
            _tprintf(TEXT("Copied *.txt to %s\n"), argv[1]);
            fFinished = TRUE;
         }
         else
         {
            printf("Could not find next file.\n");
            return;
         }
      }
   } 

// Close the search handle. 

   FindClose(hSearch);
}
