Yes.
Valid C code is Valid C++ code.
'extern "C"' will prevent the name mangling.

Therefore, write the accessing of your C++ stuffs in a standard C way, plus
use the extern "C" around its definitions in your header files that are to
be included in the plain C code.

Of course, it is possible that a slight redesign in your code may be needed,
as C has no clue as to how to handle C++ specifics. That is to say, you
might need to create some kind of C compatible wrapper around your C++
objects, depending on how the latter are structured and used.

(I think this is just an elaboration on what Nigel posted earlier)
