AFAICT your code is wrong.
The parameters of `fread()` are `ptr`, `size`, `n`, `stream`.
Your code is attempting to read `1` unit with a size of
`buf.length`. If the stream has less then a single unit of size
`buf.length` left, it has obviously read 0 units. Which it
reports.
(Looks at manual. Looks at code. SMH.)
Thanks. I've been writing C code since K&R, but I guess it _has_
been a while. Sorry to bug you for such a dumb one!
