All you need to do is look at a driver source. It's
copy_to_user(pointer to user buffer, pointer to kernel buffer, size);

Agreed, a computer is a tool that must do useful work or in the filp side..
A computer is a great toy that is used to do fun things.
To some people writing a program is as natural as eating...

Perhaps the gaps aren't as bad as they seem. Sometimes a little adapting is all
it takes.
A bit like if you move a hunded miles away you'll use a different grocery
store.
In this case it may mean learnind a few new tools.

Well I do think basic sucks (insofar as anything I do is concern) but it does
have uses.
As far as the write it yourself thing goes.. Many of us are programmers and
that's what we do..
So, I don't think it's as much "go away and don't bug me" as a genuine
suggestion to do something that solves a problem.

Irrelevant comparison. None of us has a tire factory available.
On linux we do have all the tools to roll our own software.
Also, what was refered to was making something that doesn't exist...

There's no need, the programming languages to do that already exist.

The alternative is to pay someone to do it.
But many times the "need" is already fulfilled by using a different tool set.
The whole environment and mentality with linux is different.
You can write some very fancy programs using shell scripts that call existing
tools.

I use emacs every day to do just those things.
Makefiles, C, C++, whatever.
You may have an old or incomplete version of emacs.
Emacs will usually detect the "mode" it needs to use from the file name.
It will set itself up to properly edit Makefiles, C files etc.
In fact I use a recent version of xemacs and that also has language sensitive
syntax highlighting

Excuse me, what the fuck? You are saying "<something> is needed". Wonderful,
but what makes you think that you've got a right to demand something from
anybody? You want it - _you_ go and do it. Or pay somebody for doing the work.
"For free" means "what _I_ want to do" and if you want something different -
you'd bloody better do it yourself, pay somebody for work or sod off.

There are BASIC implementations available for Linux, so this debate is moot.
You just have to know how to use a search engine. Halcyon Software used to put
out something called VBIX, a VB implementation for UNIX. I don't know whether
this product is still offered, but when you go their page they are now selling
smoething called iConverter, which ``is a technology that let Halcyon provide
Visual Basic to platform independent Java conversion in a fraction of the
normal amount of engineering time, saving you money and headaches.''. See

This is more a case of buying a different model of car, but refusing to adapt

Correct. It's easier to just learn a new programming language and write Hello
World in that.
In any case, the intellectual investment in learning VB is so slight that it
should be easy to ditch it for something else in a day.
When VB was introduced, did some people not abandon other tools in favor of it?

You probably haven't initialized values in the msg_namelen structure. Using
recvfrom might be a bit easier.

in linux you generally use one of
1) shell script
2) tcl/tk
3) perl
4) python
depending on your mood.
there's no visual basic for linux probably because no one has felt the
urge to create it. you can
1) write it yourself
2) pay someone else to write it
3) wait until someone else writes it anyway
4) stop moaning about it already

if someone likes your suggestion, they might take you up on it. why
should you think you can command someone else's time and effort?

how else would do it? in order to have a working programming language
you will need a working implementation. this is a tautology.

if you don't want to do it yourself, you must *pay* someone else to do
it for you. this is the way the world works, i'm afraid. i don't
know why you expect people to perform services for you without
compensation. you don't expect your neighbor to mow your lawn for you
out of the goodness of their heart do you? why then do you expect
them to write you a visual basic implementation?

hi
I want to make the kernel print some stuff out that i can examine -
preferably to the console, as i am playing with some aspects of the kernel
at the moment
i understand that this is what printk can do for me (although it can log to
the system or something by the look of the code).
When i call printk, where does the string i pass it go?
How do i get it to go to the console?
Thanks

There are always gaps.

Nothing has VB but Windows since it is a proprietary language. An IT
department that uses a proprietary language for critical functions is
vendor-locked by definition. Even if that language isn't from
Microsoft.
Linux has numerous RAD languages, some free and some proprietary. The
fact that there is no VB for Linux is not anybody's fault but
Microsoft's since they control the language.
>Whenever a *user* mentions this to a Linux bod they are told - "Windows

I say "use Python" or "use PHP" or "use tcl/tk" depending on what they
want to do with it.
>Linux is excellent but time & time again, if you identify a need you are

That's why they call it "user supported".

Yes in the intial release of CodeWarrior for Linux if you have an include
header with a space in it we did not parse that correctly.
For example, if "my foo.cc" contained the following include
#include "my foo.h"
the wrong thing would happen when we got dependency information back
from gcc; that is, it would end up looking like
my\ foo.cc.o: my\ foo.h
This did not affect source files added to the project.
We are going into beta testing for the next release of the �W for Linux
product, if you are interested in this drop me a note.
