I don't think that LILO will ever get that feature.
You could either write your own loader with that
feature or do it before LILO is being loaded. Most
PC's have 31KB of unused space at the start of the
harddisk, here you could place the sound and a
copy of the MBR in the MBR you could then place
the code to play the sound. That would work
independent of what OS you are using.

The Reference manual in The White Book has to say this:
A7.3.2 Function Calls
A function call is a postfix expression, ...
If the postfix expression consits of an identifier for which no
declaration exists in the current scope, the identifier is implicitly
declared as if the declaration
extern int identifier();
had been given in the innermost block containing the function call."
In other words: you can call functions without declaring them. The
compiler will declare them as being global functions returning "int"s.
No warning will be given, you are warned!

Hi,
There are several projects,
like Berlin and believe it or not "Y" ,
It also helps not using rubbish windowing manager like kde,
that like crashing every now and then.
The XFree86 4.0 allows for non socket servers as far as I can recall.

there would be at least 7 steering wheels each working differently,

Nah, it wouldn't have a steering wheel, or a radio, or
a stick, or any other snazzy paraphernalia. No seats,
no doors, actually, no body at all, just a chassis,
an engine, a gearbox and four wheels. But it would
be able to fly, when the good-looking gadget-rich
planned-obsolete car of the competition is stuck in
a traffic jam.
BTW, do they still say "robot" for a traffic light
in your nick of the woods?

Subject: Any free round-trip-engineering software tools out there?
Date: Thu, 14 Sep 2000 15:03:22 GMT
Does anyone know of any round-trip-engineering software tools supporting
for example C, C++, Fortran, and/or Java?
I have in mind something like Together, but perhaps supporting some of
the older languages as well, such as C and Fortran, and of course "price
IS an object" to paraphrase. Commercial tools like Together, although
very nice, run into the thousands of $ - clearly not suitable for the
hobbyist (am I dating myself with that term?).
With these modern tools, I especially like the fact that diagrams and
code remain in sync at all times. Are there any free tools or toolkits
which address the round-trip software engineering domain, even if
partially?

Modicum? You have to be joking. I went to your link and found

Subject: How to open a network device
Date: Thu, 14 Sep 2000 14:53:39 -0600
I am trying to perform an ioctl to my network device driver but am unable to
get past the open. I have tried the following code to no avail:
fd = open("eth0",...)
ioctl(fd, ...)
I was under the impression that opening a network device used the symbolic
name "eth0" as opposed to a file in /dev. In either case I am unable to open
the network device driver or to do an ioctl on it.
I am new to network modules (both kernel & user space). Can anyone help
point me in the right direction?
Thanks

No, opening "eth0" simply opens a file in the current working directory, should
the mode and permissions allow. If eth0 was a magic name, it would cause
problems for someone trying to just use it as a filename. Now what kind of
shitty operating system would do something like that?

You have to create a socket in the AF_PACKET address family. The type is
specified as SOCK_DGRAM or SOCK_RAW. Then you need to bind it to a particular
adapter. This is done using not a struct sockaddr_in but a sockaddr_ll, whose
'sll_ifindex' is used to specify the index number of the interface.
An alternative is to specify SOCK_PACKET type socket, which you can bind to an
interface using sockaddr_pkt instead of a sockaddr_ll, which has a character
field for getting the device by name.
The diffences between these two ways of creating the socket are in how they
handle the details of I/O. SOCK_PACKET is supposedly obsolete.

Network devices are in a different namespace, arguably it could be under /dev

Streams has been notorious for being slow, see solaris as an example, but there
has been reports of using pipes and improving X performance, by how much

Doesn't this tell lilo to put itself in the partition not the MBR, try using the

I ike the idea of devfs, but needs refining alot more. Just try the linux
boot option for the moment, then add other(s) in later.
Dont't bother with the disk lines for the moment. Do you know which
disk is the boot disk ide/scsi?.

Distribution Manager / Message Notification Server.. for Linux?
Basically, an entity (application, driver, whatever) that accepts messages
