Interfacing v code into a C++ app, is like interfacing with any other C library, with the addition, that you may have to write the C headers yourself (or you can cut/paste them from the produced C file).
If you want to call a C++ function from V, you have to export it from the C++ side, like you would do for a C app: extern "C" { int your_function(int x) } ... and then call it from the V side like any other C function. (https://vlang.io/docs#calling_c)
