C++ Project Using Singular

Hello,

I would like to experiment something using libSingular with C++.
I have successfully compiled and installed the latest version, however, I don't find any examples showing how to use the functions from C++.
For instance, how to define a polynomial ring over a finite field?

Can you please point me in the right direction?

Thanks!

for an example, see https://github.com/Singular/Sources/blob/spielwiese/doc/HOWTO-libsingular
