[newbie] Net::Pcap

[David Vallner]

I was thinking of cutting my ruby baby teeth on making something
actually generally useful. So I wonder: Would anyone find a libpcap
extension any useful? If so, I'd welcome any advice on how to start,
possibly some pointers on writing C extensions, or any decent examples
of DL usage.

For C extensions check out README.EXT in the Ruby distribution, Chapter
21 "Extending Ruby" in the Pickaxe 2nd ed., the builtin classes
(array.c, string.c, etc.) and C extensions that come with Ruby.

There's this one:

Not that that should stop you!

If you're going to write a C extension, use RubyInline:

It lets you avoid all the boring parts and focus on the fun.

Well, what do you know. I'll go off and see about something else;
pondering a web service to serve sudoku puzzles to J2ME clients and
track solver statistics...

Thanks for the link though, that should come in unbelievably handy next
semester, even though I'll probably give the instructor a heart attack
by using a library that already does packet parsing.

Oooh. Aaah. I hope boring parts include "getting the stuff to compile
using the MSVC++ toolkit". I admit I'm a very bad C programmer when it
comes to gory details like writing proper makefiles.

Cheers for all!
