Is there any C-language (or even C++) OpenID library around somewhere?

Question

One of the OpenID developers pages advertises one, but that turns out to be a typo. I find none on Google.

Does anyone know of an OpenID interface library written in the C¹ language?

Thanks!

¹ Held by some to be archaic -- so '70s dontcha' know -- but there are those who love it.

Answer 1

I don't know of one for C, but libopkele appears to be one such library for C++. However, I have never used it, so I cannot vouch for it.
