Summary: readdir() is probably screwed

The problem sounds like readdir() is returning garbage. I've heard
things about the 9000/500 directory structure being "interesting".

In a posting talking about unipress emacs mg@unirot.UUCP (Mike Gallaher) says:

	However, I have spent many hours of my life compensating for the
	differences between HPUX on the 500 and on everything else that also
	claims to be Unix System V.  (There are more "special case"
	conditionals in the Emacs code for the 500 than for any other
	machine...)  When I wrote that flame I had just wrestled with the
	following differences:

		- the file system is neither berkeley or v7/SysV, so the bsd
		  directory emulator didn't work until I taught it
		  how.  (HP does supply its own BSD directory
		  emulation, but it wasn't documented for the 500, at
		  least that I could find).
		 - The tty driver does not support VMIN/VTIME.  This *is*
		  documented, but it depends on which hardware
		  interface you have, which is not easy to detect (even
		  by looking at the box!).


I suspect your problems are related. You should contact whoever sold
you the system and ask  about reading the filesystem.
