[GRASS-dev] which library has CC_u2ll_spheroid_parameters?

[Alessandro Frigeri]

Hello,

Looking for a function for converting pixel's coordinates to
geocentric x y z, I've found that CC_ll2geo definition is still
included in the code - generating documentation here
http://grass.osgeo.org/programming6/CC_8h.html.   It was a bit
misleading to find the declaration but not the definition.

Is there some example around to perform conversion of pixel's
coordinates to geocentric x y z using libgrass_gproj?

Regards,

Alessandro
