I don't think this has been tried: but I'm not a faust dev, so perhaps
there's some research somewhere hidden way...

Yes, this can be used to *call into* C code from FAUST. An example from a
FAUST based wavetable synth:
C header:
https://github.com/harryhaaren/openAV-Sorcer/blob/master/faust/wavetableReader.h
ffunction code in FAUST:
https://github.com/harryhaaren/openAV-Sorcer/blob/master/faust/main.dsp#L44
This is C (not C++) as the FAUST language itself is functional not OOP, and
hence calling C++ (with classes etc) is not normal. Calling C is easy
though: just pass in the data needed, grab the return value.

Indeed: and the generated code is generally a C++ class representing the
FAUST dsp code. Note that different backends to faust may or may not
utilize the C++ code, but I'll let somebody more knowledgeable jump in here
:)
