Using Approach A there is the issue that type safe linkage is lost, but this is only for C functions called from C++ or vice versa. I'm convinced that it should be possible to mix c and c++ files in a project. extern "C". The approach I took was using separate .o files compiled into a single .so file, which was then added during vcs compilation with the rest of the SV files. Projects work if they are all C or all C++, but when mixing C in a C++ project, the C file is not included at link time so errors result. Consequently, it is possible to create a project that uses elements of both languages. In Visual Studio, it is possible to mix C++ and C code, C++ files should have cpp extension, C files should have C extension, the compiler takes care of the rest. 2 Answers2.

C++ is capable of supporting a much richer set of types than C is, and there always seems to be some work involved in preserving C++'s type expressiveness in C. Incidentally, the facade is incredibly ugly at the moment. Or, taken in the opposite direction: you want to use a C function inside your C++ library. C++ exception handling can catch and preserve the unwind semantics in all modules compiled with the /EH compiler options, which enable unwind semantics. 2.
