   Does the FTP definition include a C level protocol?  ... How is the
   calling interface FTP currently defined,

The FTP protocol spec describes octets flying over a TCP connection,
which is routed by IP.  It doesn't care what language you use, nor
specifically how you persuade the octets to fly.

   and where can I read about this definition?

FTP is defined in RFC959.  It is clarified and somewhat expanded in
RFC1123 section 4, which also specifies a user interface but not a
programmer's interface.

Your operating system may provide library calls to manipulate TCP
sockets, which may give you what you want.  Look in the documentation
provided by your software vendor.
