Hrmph.

God only knows what Windows 2K might have done with its file permissions
system (or lack thereof)...

What are the permissions settings on the files that work versus those that
don't?

Just for fun, if fgets doesn't like it, does fread like it?

Remote, but distinct, possibility: Bad hardware.

If the underlying hard drive is kerfraggled, then you *could* see the
behaviour you're getting -- The file seems to open okay, but an attempt to
actually read data conks out on a bad sector.

Can you skip the fgets section ENTIRELY and just fclose() it? Once the
handle is known to be corrupt (by a bad sector) then fclose() will
probably die, but if you don't attempt to read a bad sector, fclose()
shouldn't have much to do, and should succeed.

Certainly doing a backup and running a disk check wouldn't hurt, to
eliminate the hardware possibility.
