You do know what the static tag does? It should be fairly obvious why
static is used. If not check K&R.

I want to change the initial window size to 4 segments. How can I do this
for a linux kernel. Do I have to modify the ketnel source or is it a
configurable option/setting. Any help in this area is appritiated. Thanks in

See an older thread in this newsgroup titled
opening ethernet as a raw device
In short, you do this with appropriate calls on a socket.

In a hosted platform like a PC, initrd would be loaded via a loader
such as syslinux, lilo, or grub. They pass to the kernel either the
preloaded image for initrd, or where to read it (usually floppy).
In your case, I suspect you need to have the initrd image loaded
before the kernel starts, as that would be the way it would be when
the system is ROM'd. Then it's a matter of passing that info to
the kernel by the code that branches into the kernel startup.
If by chance you get get a Disk-On-Flash, then use that as a device.

Where did the library get installed? Make sure that directory is
listed in the /etc/ld.so.conf file. Then run "ldconfig" to update
the /etc/ld.so.cache file. Maybe Apache can be configured with the
location on its own. See "man dlopen" for a description of the
library call that Apache is probably using so you can get an idea
of what information it has to have (or figure out) to load a shared
library to be a module.
Another option is to not use DSO and compile everything in all at
once.

Seems that way to me, too, especially considering their authority
DNS servers don't even know what "tizek.com" is.
And this is the Nth site to claim this, where N is significantly
larger than the number of portal sites that will ever see the light
of visiting users, much less actual ad revenue.

Besides, I'm too busy building my own premiere Internet portal for

This is helpful for half of the stuff I want to do, but
it still goes through the BSD socket library, and probably
also goes through the INET subsystem.
What if someone wanted to write their own protocol based
on ethernet? How would it be done?

You write a driver module that installs a handler for the
Ethernet protocol number in question.

I see, from other newsgroups, that it is so.
Unfortunately, such vast levels of desperation are suggestive that
it's a "sinking ship" long before it ever gets launched.
Sort of like a fellow I once knew called Bruno; he'd meet a girl that
somewhat interested him, and almost instantaneously launch into trying
to "offer her a ring." I don't particularly _like_ calling people
"losers," but anyone that uses the term would feel it hit the mark
with Bruno...

I should have added that "dev_add_pack()" is the kernel
function you call to do this. I don't know what happens if you
register to handle a protocol number that's already being
handled (e.g. IP or RARP).

Subject: a newbie in linux device driver writing.
Date: Tue, 17 Apr 2001 00:29:43 GMT
Hi! all,
I am quite new in writing linux device driver. But anyway I have to
take over
and maintain some serial board driver source which was written by
someone else.
The program flow is ok for me this moment. But still got 2 questions
here.
1.I found very hard to find the kernel level function specification
which can support
driver writing. for example, like "wake_up_interruptible" or event
scheduling
mechanism description, or "ioremap". Maybe I can find some clue from the
kernel
header files and organize its opertion by myself. But it is that a
correct way?
Is there any place can give me such fucntion's example and
explanation in one time?
2.I found the driver code have to register a "callout" serial driver
except registering
the normal serial driver. and the from the linux source I saw the
serial.c do the similar thing.
I wana know why should we put it over there and what is that?
Is any one can tell me how to find out it?
thanks!

I must support multi card of some pci device in driver. (all card is

Because interrupt is sharable, 2 or 3 card can get same interrupt

So, I want to know pci info - as example, devfn in struct pci_dev -
which
cause this interrupt When ISR is entered. Thanks for reading, have a

When I compile my device driver, kernel version is put in it.
(I compiled device driver with option -O2 -DMODULE -D__KERNEL__
-DCONFIG_PCI )
So, it doesn't run in different version of kernel.
I can load it with insmod -f , but I want to know how to make kernel

kernel.(all 2.2.x version

Date: Tue, 17 Apr 2001 01:16:38 GMT
First of all, thanks to all who replied. Well, maybe I do not have a
complete understanding of what "static" really does. I know that I
have to use "static" if I want the variable to be remain in memory
even after the function has exited. This also means increase in speed
of execution as the variables do not have to be created next time the
function is entered.
However, why would "static" help in preventing namespace pollution?
Why would declaring "static" make a global variable visible only
within one file? Can anyone please explain to me in greater detail?
(My C programming textbook didn't mention anything more abt "static".)
Thanks,

Because that's what it does. Scope of global static objects is one file.
They are not exported.
>(My C programming textbook didn't mention anything more abt "static".)
So throw it into the garbage and get a decent one. K&R would do nicely -
you can always read about the differences introduced by ANSI later.

If I'm reading you correctly, you are wanting to know which card caused
the interrupt. You just have to check the status on all the cards to
see.
