Subject: RE: testing for a remote file to include file on a Windows mapped drive
Date: Sun, 20 Apr 2008 11:28:47 -0700 [thread overview]
Message-ID: <000a01c8a314$5fff7630$0200a8c0@us.oracle.com> (raw)
In-Reply-To: <BNELLINCGFJLDJIKDGACKEPJCGAA.drew.adams@oracle.com>
I'm returning to this thread because I don't know what was finally done wrt what
I asked for in starting the thread: Treat a file name with a Windows mapped
network drive as remote but one with a local drive as not remote.
Could someone please summarize what was done about this? The thread seems to
have drifted away from its target, and I can't tell what the outcome was.
I'm still using the code I mentioned (see below), which tries NET USE on
Windows. Is that part perhaps unneeded now, because an equivalent is done by
Emacs itself? Note that while I find the NET USE code to be quick, a couple of
users have reported that it can seem to hang. Suggestions about that?
Also, could someone please reply specifically to my last message in the thread,
below (e.g. `file-remote-p' vs `ffap-remote-p')?
Thx.
