How to start learning FreeBSD OS Programming

[Weinter]

I have very basic C knowledge I like to know how to start on FreeBSD development :)

[lyuts]

I think you should improve your knowledge in C, then learn about UNIX systems in general (and BSD in particular) and then move on to FreeBSD development.

You could start for instance with the FreeBSD Developers' Handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/

Fixing PRs would be a good start too.

Hello Community!

I want to learn, how the kernel of FreeBSD works. Can you advise any books or websites?
I can program with the languages C,C++ and a bit x86 Assembler (AT&T Syntax, I used the GNU assembler some months ago), so I think I can understand code examples and such things.

Best Regards
Christian

This is probably what you want: The Design and Implementation of the FreeBSD Operating System (http://www.informit.com/store/product.aspx?isbn=0201702452)

It is kind of old, but still has useful information.

FreeBSD's own system documentation is great. If you already know a little about the general internals of Unix, then you might want to check out the manual pages for system calls (http://www.freebsd.org/cgi/man.cgi?query=(2)&sektion=&apropos=1&manpath=FreeBSD+7.0-RELEASE&title=Section%20) and kernel interfaces (http://www.freebsd.org/cgi/man.cgi?query=(9)&sektion=&apropos=1&manpath=FreeBSD+7.0-RELEASE&title=Section%20).

If you already have C programming knowledge, you can read this book :

Designing BSD Rootkits : An Introdution to Kernel Hacking

http://www.amazon.fr/Designing-BSD-Rootkits-Introduction-Hacking/dp/1593271425

I'm actually reading it, and I love it :D

I read that one too. It's really nice and I'm doing several projects because of that book.. Yay! :e

[danger@]

I have got this one in my book shelf, but unfortunately haven't had a time to read it yet ;-(

[netrom]

Yeah, it's like that almost all the time. Have quite some books on my own shelf I never get time to look into..

[matteo@]

The 2nd edition of Advanced Programming in the UNIX Environment should be a good start too.

Great article: http://www.r4k.net/mod/fbsdfun.html

this article is quite understandable for starting kernel programming:

The Design and Implementation of the FreeBSD Operating System looks interesting, I think, I'll buy it.

The other books and websites are interesting, too. I'll have a look at them, when I've got enough time.

It is a very good start reading the handbook!!!
