Subject: API for excess DOS file attributes??
Date: Thu, 29 Sep 2011 22:59:09 +0300	[thread overview]
Message-ID: <j62imi$ls1$1@dough.gmane.org> (raw)

Under Windows this done through:

   GetFileAttributes()

call. I grep sources and find only 2 occurrence:

./src/fileio.c:1878:      attributes = GetFileAttributes (filename);
./src/w32.c:2630:  else if ((attributes = GetFileAttributes (path)) == -1)

which used for internal purpose...

So I think that I can not excess to this data from Emacs
(native Windows build).

I try rewrite 'follow-cygwin-symlink' from:

   http://www.emacswiki.org/emacs/setup-cygwin.el

for more strict conformance of definition of symbolic link
in Cygwin (from 'cygwin-ug-net-nochunks.html'):

   The file style symlinks are files containing a magic cookie
   followed by the path to which the link points. They are marked
   with the System DOS attribute so that only files with that
   attribute have to be read to determine whether or not the file is
   a symbolic link.
