win32utils devel - Nov 2004 - File.open on a directory?

Hi all,

Windows 2000
Ruby 1.8.2 RC9

Is it possible to call File.open on a directory in Windows?  I always get 
Errno::EACCES, even though there are no special settings on the directories 
I''ve tried and I have full access.

The open function cannot open directory on Windows. it returns EACCES if given
path is directory.

You should use CreateFile function to open directory.
Opening a directory with CreateFile requires the FILE_FLAG_BACKUP_SEMANTICS
flag.

Time for the ''dopen'' class method. :)
