Hello,

another wishlist entry (old one):
read/write NTFS alternate data streams via openat(O_XATTR)

Opening individual streams might be easy, as Corinna pointed out that
cygwin_attach_handle_to_fd() can be used for that (i.e. open stream,
and attach handle to fd via cygwin_attach_handle_to_fd()), but the
virtual XATTR dir might be a challenge (beyond my skill at least).

Thanks,
Martin

Subject: Cygwin tools to read/write NTFS alternate data streams?
To: <cygwin AT cygwin DOT com>


Hello,

Does Cygwin have tools (modified /usr/bin/dd ?) to read/write NTFS
alternate data streams?

Thanks,
Martin
