writing modules?

Morning,

I would like to make my own apache module (in C) for Linux but have no
idea where to start. Any guides on doing this?

Thanks!
Zach

You may want to try out http://www.apachetutor.org/ . I can also
recommend the book (on the page), it's really worth the price.
This helps you getting familiar with general module structure.

The apxs tool (delivered with Apache) will get you started
with a sample module. I think it was axps -g -n .

After that, try to look at modules which offer some related
features to the one you want to write. Look how they did it, try
to understand why and keep experimenting. Try to understand the
concepts of the APR. Just go through the online documention of
the APR functions as you go through code of other modules.
E.g. pool are a very important concept which you should get
familiar with.

Regards,
Edgar

I assume you are developing for Apache 2?
You might want to do some searching and reading on Apache modules API:
http://www.linuxdocs.org/HOWTOs/Apache-Overview-HOWTO-12.htm l
http://modules.apache.org/doc/Intro_API_Prog.html

As well as other 'house keeping' activities that must be done:

O'Reiley has some pretty good books detailing the process....

I'd read some books:

http://www.amazon.co.uk/Apache-Modules-Book-Application-Deve lopment/dp/0132409674/ref=sr_1_1?ie=UTF8&s=books&qid=1259852 319&sr=8-1

or

http://www.amazon.co.uk/Writing-Apache-Modules-Perl-Customiz ing/dp/156592567X/ref=sr_1_2?ie=UTF8&s=books&qid=1259852319& sr=8-2

if you still use apache 1.3.

http://www.amazon.co.uk/Apache-Definitive-Guide-Ben-Laurie/d p/0596002033/ref=sr_1_6?ie=UTF8&s=books&qid=1259852319&sr=8- 6
is ok, but doesn't really go in-depth about module development.


Cheers

Tom

Don't forget the modules in the source distribution, particularly the examples.

httpd 2.2.x has modules/experimental/mod_example. httpd trunk/2.3.x,
for future httpd 2.4, has improvements in modules/examples/mod*.c, but
some use APIs that don't work in httpd 2.2.x.

One way to use the large set of modules in the source distribution is
when some httpd (ap_) or APR function looks like it may solve a
problem; search for the uses of that function throughout the source.

No, O'Reilly doesn't have any books on the subject at all. The only
book on the subject is Nick Kew's book.

If you're referring to the Eagle book, please note that it's ten years
old and focuses primarily on Perl. It was a good book at the time, but
is now mostly a bookend. At 700 pages, it plays that role effectively
and attractively.

Harsh, thats one of my favourite books :/

The Apaloosa book (Apache : The definitive guide) has 2 chapters on
2.x module development and API, numbering ~ 100 pages, which isn't
much more than the Eagle had - like you said, mostly perl.
