How can I use rkdb in other packages ?

[statquant]

Hello I'd like to use rkdb in another package, actually what I am after is the R <-> kdb conversion functions.
Would you be kind enough to let me know how I can use the C functions from_any_kobject in a C++ code from another package ?
I found description in http://adv-r.had.co.nz/C-interface.html but that's a bit blurry to me.

Kind regards if you can help
