How to control wifi?

[erupter]

I did a search but came out empty handed.
Is there some library to control wifi?
Set up ad-hoc connections, managing bssid, granting access to new hosts, and the likes.
Can this be accomplished by a program?

I googled a lot for such libraries but didn't get anything , any help will be appreciated.

Thank you

Thanks cheesehead!

But chillispot is now defunct, http://coova.org/ is the new one.
