In regard to the one instance returning pointers or references to local
variables, yes.
In regard to using pointers or references to refer to local variables,
no. A reference must go out-of-scope before the variable it refers
to. A pointer, on the other hand, can be reseated to point to a variable
declared in an enclosing scope. Once execution exits the scope, the
pointer is dangling.
Thus, references are safer both theoretically and practically than pointers.

This has me curious, I've heard of court cases where NT was declared

I asked before, but no one answered. Does unlink cause the ext2 filesys
to immediately process the removed inodes/blocks etc. so that removing
large files is costly. I find with the latest RH 6.0 that I seem to
notice the time taken for rm to remove big files (500Mb). I don't think
it was so intrusive under 2.0.37.

Subject: printer problems
Date: Tue, 31 Aug 1999 12:02:54 -0600
I am experiencing two problems with my printer, which is an hp laserjet
clone, (Brother HL6)
1) I can only get my printer to print directly after I print a demo page on
the printer, otherwise it won't respond to the lpr command at all, the hard
drive light will come on, but no printing occurs. Any Ideas on why this is
happening and possible solutions?
2) The other problem I am having is with my filter, and I'm not sure if this
is related to my first problem. I am trying to make a basic filter in a bash
script executable file called filter. (I have no printtools or controll
panel due to a small hard drive). The problem is I cannot figure out how to
get my filter to append a carriage return controll character on the end with
a new line controll character.
here is what my scrip looks like:
#!/bin/sh
if [ "$1" = -c ]; then
cat
else
sed -e s/$/^M/
fi
# the "echo -ne" assumes that /bin/sh is really bash
echo -ne \\f
I believe I need to replace "^M" with somthing else because all this filter
actually does is print a "^M" after each line, insead of making a c.r.
happen.
PLEEEAAASE HELP ME! OR TELL ME SOMEONE WHO CAN.

I was also an OpenLinux 2.2 user and couldn't get any of these versions
to work. I even tried Caldera support but they were no help.
Unfortunately, I also came across this problem on some other software
packages that I had downloaded. I ended up ordering Mandrake 6.0 (Red
Hat 6.0 optimized for pentiums) from cheapbytes.com (cost around $2) and
I'm much happier. Not only did those software installation problems go
away but Mandrake came with many more applications and utilities
including several window managers besides KDE, though I still use KDE
most of the time. I suggest you try out some other distributions of
Linux since they're only $2 a piece at cheapbytes.

Go with the ELF version.
a.out is for old (very old) distributions. RH 5.x is in RPM format but
is packaged specifically for Redhat.
It's possible to use this on Caldera, but path's and such would
probably differ.

Subject: Re: *nix vs. MS security
Date: Tue, 31 Aug 1999 18:31:06 GMT
Anyone who has ever gone looking for MS product support on the web will
tell you the same thing: "Microsoft thumbs their noses at the little
guy." You can look for days on their support pages, and come up empty
handed. Unless you're willing to pull out your credit card don't expect
to find easy solutions to your network problems.
Make no mistake, Microsoft trips over themselves to turn out products for
businesses. That's where the money is. Even the operating systems that
turn up on the home machine are originally sold to businesses under OEM
licenses.
In other words, Microsoft doesn't give two cents about the individual
user. They're more interested in selling software and technical support
licenses to the "big guys." There is no documentation easily availible
for Microsoft products... and this is done intentionally. If you're a
business, you pay for the documentation. (Office 97 resource kit for
example.) Thus, you have the resources to set up all the security
features in your network.
But the individual can not afford this. And most people purchase they're
OS with the computer... thus it's usually an OEM license, from which
Microsoft has completely washed their hands.
So the professor's comments would have validity depending on the
application. If the OS is located on a 200 user WinNT environment, I can
guarantee you that there is a Microsoft support line nearby being used on
a daily basis. It'll be a secure net, but these people are paying tons of
cash for this support.
I would ask the professor to clarify his position before I jump to condemn
him. Ask him how much money is allotted to maintain this security.
PS. Of course there's the whole "liability" issue too... where Microsoft
never admits it's mistakes, lest millions of users demand money back.
This isn't the best environment in which to educate their customers on
potential security flaws.

It sounds like you want a restricted shell. Users cannot change their
directory (cd <another directory> doesn't work), cannot change their
environment etc.
Look up restricted shell and keep your file system intact. It'd be
murder to keep up with multiple versions of everything.

I am using ghostscript to plot large files. I am printing to an HP 350C
using the dnj650C driver. This all works well; the plots are scaled
correctly and plot correctly.
I am having a problem getting ghostscript to exit. Once the job ends,
the plotter ejects the page, and lpd should end the job.
gs never exits; it sits there consuming 2-3% of CPU cycles and lpd never
clears the queue.
I am guesing that ghostscript is waiting for a command or something.
Any ideas?
This is my script invocation (at this point, the file sits in $TMPFILE):
yes | ghostscript -q -sDEVICE=dnj650c -sOutputFile=- -r300x300
-sPAPERSIZE=archD $TMPFILE
TIA,

Subject: mformat complains on Red Hat 5.2
Date: Tue, 31 Aug 1999 20:08:26 -0230
Hello,
After upgrading to Red Hat 5.2 I realize that the mformat utility from
the mtools package which is used to put a DOS filesystem on a floppy
without having root access is no longer working as it used to on Red Hat
5.0.
As root I type (after inserting a write unprotected flopy):
# mformat a:
mformat: Non-removable media is not supported (You must tell the complete
geometry of the disk, either in /etc/mtools or on the command line).
I have no idea of what the disk geometry of my standard 1.44in. floppy is.
Could someone please tell me how to fix this (either as by editing
/etc/mtools as root or by specifying the command line arguments as a
normal user).
Thanks for your hlp,

Yeah , I know about inittab, but I'm specifically looking to be enable and
disable it from certain programs. Like I said , XF86 can do it so their must
be some system call buried in libc or similar to be able to do it.
