Another good reference, especially for the art of good OO Design
practices, is Jesse Liberty's "C++ for Linux in 21 Days" --- while
Stroustrup is essentially for understanding C++ per-se, it doesn't
hurt to have a good desk reference that describes the particular
system you are using with RH.
And I'm not just saying this because, as the tech reviewer, I tortured
Jesse until his 21-day guide swelled to 28 days ;)
As for libraries, a very promising candidate is the CommonC++ which
is now available through www.gnu.org

Do you want to do this across all filesystem types? Or just for ext2
only? If your intent is to change the behaviour of unlink() to move a
file to a garbage area and later empty the garbage, you need to consider
a lot of things about how this should work.
1. How will you empty the garbage?
2. What do you want unlink() to do is it is a file with multiple links?

With ldconfig you can change libraries around and use a different one.
Is that how you are intending to replace unlink()?

The instructions are usually at the end of the file xxxx.c (xxxx is the name
of the driver). See if a makefile came on the disk. The instructions for
compiling and installing the driver as a module are in the source code or the
makefile, at least they were on the D-Link DFE-530TX+ I recently bought. The
driver might also already be in your kernel you can either build it as a
module or rebuild your kernel.

If you put the name of a shared library in the environment variable
LD_PRELOAD then it is loaded after all the libraries that a program
requires and can override functions in those libraries. That wouldn't
work for statically linked programs or those that call system calls
directly.

.deb files are simple archives, i.e. you can unpack them with 'ar x'
(best do it in an empty directory, so that you don't have to search
the pieces afterwards)
there also is an 'alien' utility that lets you convert between
different package formats.

Does the PCI architecture even allow this at the hardware level?

Yes. It is perfectly valid. Keep in mind though that many systems
have several PCI buses, which may not even be visible to each other.

Does anybody have got a technical guide about AP138B parallel port chip
(also mentioned in partport.c driver)?
An answer sent by e-mail to address mailto:[EMAIL PROTECTED] would be

Hi,
I need a function which provides nano-sleep in kernel code, but I don't
want to use the structures from linux/timer.h 'cause they're too complex
for my needs. Just a function that halts my driver for specific numbers
of milliseconds.
Any ideas?

Of course it does, when a PCI card does DMA, it accesses the target by
setting the address lines of the PCI bus. It does not know or care if the
addres is decoded by system RAM or any other device. For example for
devices that do this, see the bt848 driver.
Are you sure NT can't do this? That would mean that bt848 cards would be
practically unusable under NT.

Sure. It's a PCI hardware issue. Linux can't allow or disallow it: as you
said, it doesn't involve the CPU.
>I know that NT doesn't support this but does Linux?
Again, the software can't "not support" it. It's a function of the PCI bus
hardware and the PCI devices, not the OS.

My 2.4.0test8 boot dmesg has a line:
"Limiting direct PCI/PCI transfers."
just after setting up the APICs.
A quick grep of the source tree shows this comes from
drivers/pci/quirks.c , and it seems they aren't completely
disabled.
