C And C++ Coding Standards

Question

What are best practices with regards to C and C++ coding standards? Should developers be allowed to willy-nilly mix them together. Are there any complications when linking

Answer 1

One should generally assume that c++ can throw exceptions, hence the c wrapper functions in your block, ought to catch them, and morph them into nice error codes that the c caller can digest.

extern "c"
{
    int nice_c_function_interface
    (
        void
    )
    {
        int returnStatus;

        try
        {
             returnStatus = nice_cpp_function();
        }
        catch (NiceCppException& that)
        {
             returnStatus = that.failure_code();  
        }
        catch (...)
        {
            cerr << "Oh Worse! an unexpected unknown exception" << endl;

            returnStatus = -1;  // Horrible unknown failure
        }

        return returnStatus;
    }
}
