Extended functions in embedded code

[Ervin Hegedüs]

Hi,

I've read many docs and examples, then I made a usable test version. If
anybody interested about this (and for the mailing list archives), then it
could be found here:

https://code.activestate.com/recipes/579110-add-function-to-__builtin__-module-through-c-api/

Hope this helps, and many thanks for all help.

Cheers,

a.

ps: after I've done, I realized, that will not good for me :). Nevermind,
this was a funny work.
