Syscalls: When can I use "cond_syscall()" macro?

Syscalls: When can I use "cond_syscall()" macro?

[Gustavo da Silva]

Hello, friends!!

How are you?!

Im studing the linux kernel, to be part of the community!!

Anyone know where/when can I use the con_syscall() macro?!

And another question:

Where are the file "unistd_32.h"?! I'm not founding it in the
"arch/x86/include/asm/" directory!!

[]'s
Peace.

I think you can answer this for yourself:

  $ sudo updatedb && locate unistd_32.h

or

  $ cd kernel-tree && find . -name "unistd_32.h"

Mine is here (for x86):

./arch/x86/include/generated/asm/unistd_32.h

Welcome to kernel-land :-)

Hi Ezequiel! How are you?!

So, ...Hmmm...

Im using the following url to navigate by the sources (hehehe)

http://lxr.linux.no/linux+v3.4.4/arch/x86/include/asm/

I have not done the download of the sources, yet.

So, just navigating by the sources, the link to the unistd_32.h was broken.

Well, I will do the download (if I have not one here in some pendriver)...
...!

Thx!!

  the file you're referring to is a *generated* file -- it isn't
present in a pristine kernel source tree, it will only be created by a
configuration and/or further steps, such as "make modules_prepare".

If you want to browse sources and middle-to-big size projects, I
seriously recommend
you to use ctags [1]. Once you get used to it, it's a true wonder.

In fact, linux kernel have them incorporated, so you only need to do:

$ make tags

Of course, supposing you know how to use vim or emacs :-)

I've just had a similar discussion with some co-workers.
Make no mistake, if you want to be serious programmer: vim or emacs.

Ok!!

I'll use vi/vim/emacs+ctags!!!

I'm a Java EE developer (who loves binary manipulation & low level
knowledge), so I just use Eclipse IDE. (Eclipse IDE nnnnnnoooooottttt!!!!)

I'm creating an environment to start the research&development about the
kernel.

You keep not following the tips by the way :-)

Someone who wasn't following this thread probably would ask, which
tips did he not follow?

You see what happened? Because you top posted your answer (again) we
have lost the context of this conversation.

Most people in this mailing list are very nice and are willing to help
but also they are very busy and can be a little grumpy when they have
to repeat the same thing over and over. So please listen to Ezequiel,
Mulyadi and others when they give you advise.

Good luck and best regards,
Javier
