C ++侦听网络驱动器上的修改-Windows

Question

我试图在CodeBlocks中运行此代码以侦听文件夹中的修改，但出现错误。我是一个全新的人，所以我不知道发生了什么...

    if(argc != 2)
    {
        _tprintf(TEXT("Usage: %s <dir>\n"), argv[0]);
        return 1;
    }

    WatchDirectory(argv[1]);

   DWORD dwWaitStatus;
   HANDLE dwChangeHandles[2];

 // Watch the directory for file creation and deletion.

  dwWaitStatus = WaitForMultipleObjects(2, dwChangeHandles,
     FALSE, INFINITE);

  switch (dwWaitStatus)
  {
     case WAIT_OBJECT_0:

     // A file was created, renamed, or deleted in the directory.
     // Refresh this directory and restart the notification.

         RefreshDirectory(lpDir);
         if ( FindNextChangeNotification(dwChangeHandles[0]) == FALSE )
         {
           printf("\n ERROR: FindNextChangeNotification function failed.\n");
           ExitProcess(GetLastError());
         }
         break;

     case WAIT_OBJECT_0 + 1:

     // A directory was created, renamed, or deleted.
     // Refresh the tree and restart the notification.

         RefreshTree(lpDrive);
         if (FindNextChangeNotification(dwChangeHandles[1]) == FALSE )
         {
           printf("\n ERROR: FindNextChangeNotification function failed.\n");
           ExitProcess(GetLastError());
         }
         break;

     case WAIT_TIMEOUT:

     // A timeout occurred, this would happen if some value other
     // than INFINITE is used in the Wait call and no changes occur.
     // In a single-threaded environment you might not want an
     // INFINITE wait.

        printf("\nNo changes in the timeout period.\n");
        break;

     default:
        printf("\n ERROR: Unhandled dwWaitStatus.\n");
        ExitProcess(GetLastError());
        break;
     }
   }
}

void RefreshDirectory(LPTSTR lpDir)
{
   // This is where you might place code to refresh your
   // directory listing, but not the subtree because it
   // would not be necessary.

   _tprintf(TEXT("Directory (%s) changed.\n"), lpDir);
}

void RefreshTree(LPTSTR lpDrive)
{
   // This is where you might place code to refresh your
   // directory listing, including the subtree.

   _tprintf(TEXT("Directory tree (%s) changed.\n"), lpDrive);
 } 

我得到的错误是：

`_tsplitpath_s` was not declared in this scope
