fstat and filenames

With respect to file names, you need to remember that there may not be
a unique answer.  A file handle's metadata doesn't keep information
about how it was opened, just the inode.  That inode could belong to
multiple directory entries, or none -- this is why, as the fstat(1)
manual points out, "there is no mapping from an open file back to the
directory entry that was used to open that file."

As far as unix domain sockets, I don't understand the question.  Sorry.

Be well.
