How do I use the Gnuradio GRC XML RPC client or server components?

How do I use the Gnuradio GRC XML RPC client or server components?

Please understand, I know nothing about networking, client, server, rpc,
marshaling, sockets, Python and all newer programming environments.
However;
I do know C,C++ and understand Windows messaging, wait for single
object,
wait for multiple objects and similar Windows API stuff. Not sure if
there
is a counterpart in Linux.
I want to use an external program, written in Pascal, running on the
same
machine and independent from Gnuradio, to control variables on the GRC
flow
graph. Specifically, I want to control the frequency, gain and more as
needed of an Ettus B200 SDR. The Pascal program runs natively, on Ubuntu
Linux; it does not require wine or any other Windows emulation. I know
this
may be difficult, as most examples are scripted in Python.
Any help is greatly appreciated.
