If I understand correctly, I have to use ndn-cxx together with the rules defined by the protocol to perform the operations I need. For example, to request the creation of a face, I could use as described in https://redmine.named-data.net/projects/nfd/wiki/FaceMgmt#Create-a-face

That's correct, but please note that you don't have to reimplement the
management protocol from scratch with Interest and Data. ndn-cxx
already provides a higher level API that you can use to manage
(certain aspects of) NFD directly from your application. See for
instance ndn::nfd::Controller
(https://docs.named-data.net/ndn-cxx/current/doxygen/classndn_1_1nfd_1_1Controller.html)
and other classes in the ndn::nfd namespace. The documentation isn't
great, but as Junxiao said, this is exactly the same API used by nfdc,
so you can take a look at nfdc's code for inspiration.

Best,
Davide
