Hello. I was wondering if there is a portable way to determine if 2 different paths actually reference the same file.
I have read this thread but is Windows-specific.
AFAIK, fstream isn't suitable for the job.

A:
Boost.Filesystem, although I doubt it will go so far as to resolve hard links and junctions when giving you a canonical path.

The documentation suggest otherwise: http://www.opengroup.org/onlinepubs/000095399/basedefs/xbd_chap04.html#tag_04_11

What's the connection between Boost.Filesystem and that documentation?

Symlinks, hard links, and junctions are one problem. And then there's also the problem of "short names" (think 8.3 alternate file names) in the Windows world.

@wrang-wrang: stat here: http://www.boost.org/doc/libs/1_40_0/libs/filesystem/doc/reference.html then scroll down to the point "POSIX Pathname Resolution"

Ok, thanks. So symlinks will be resolved when obtaining a canonical path, but probably not hardlink/junction?
