NTFS junction

H4 has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

I'm trying to traverse a Win32 NTFS directory tree ignoring junctions. Unfortunately for junctions the -d operator returns 1 (i.e. a true value), and the -l operator returns "" (a false value), so I cannot tell it apart from a "normal" directory. The stat function seems not to help either. I've searched up and down the internet but nobody seems to have come across this issue so far.

Any ideas? Thanks!

Win32::Symlink's `readlink`?	[reply] [d/l]

Looks promising although I'm not sure that a junction is the same as a symlink. The builtin `readlink` function returns `undef` for each directory entry, junction or otherwise. Anyway, I cannot compile the Win32::Symlink module - MS's cl.exe complains about the identifier W2AHELPER which I cannot find in any of the headers which VC++ express installed.

Looks promising although I'm not sure that a junction is the same as a symlink. The module doesn't specifically specify that it uses junctions to create symbolic links, but it's the only kind of symbolic link that's supported by NTFS as far as I know.	[reply]
