[Proj] geod C library?

[Evan Miller]

Hi all,

I am looking for the functionality provided by "geod" and "invgeod" (great
circle calculations) wrapped up in a plain C library. I found Charles
Karney's Geographic Library, but that's C++.

Does anyone know of such a library? Is there any reason (other than time and
effort) that Proj.4 doesn't provide a geod API?

Thanks,

Evan Miller
