Subject: expand-file-name, DOS/Windows, and directory separator

Message-ID: <87czjodn8m.fsf@ericabrahamsen.net> (raw)

Hi,

My reading of `expand-file-name' (I don't really speak C) is that, if we
run it over a file path produced by an external process on a Windows
machine -- meaning path strings where the directory separator might be a
backward slash -- it will normalize that separator to a unix-style
forward slash. It looks like fileio.c:1247 calls dostounix_filename, and
I'm assuming that's what that does.

Is that a correct assumption? Can I rely on that behavior? Again this
isn't a file path produced by an Emacs function like `directory-files',
but by an external process returning a list of file names into a process
buffer.

TIA,
Eric
