I should also add that, in my opinion, what you call is_file is probably is_stream. Streams can be read with an ifstream, but they aren't necessarily stable, seekable or finite. Take /dev/urandom, for example.
I agree at least in theory. Although people call these things "files" all the time.
A hypothetical OS that allows directories to be opened with an ifstream may reasonably answer true to both is_stream(p) and is_directory(p). Or maybe not. :-)
I think not. Dividing the world into non-overlapping categories is much easier:-) --Beman
