plc.h:
#ifdef __cplusplus
extern "C" {
#endif
...usual header stuff
#ifdef __cplusplus
}
#endif
As to the "Hungarian notation": the C++ name
mangeling is far more powerful than Windows' Hungarian notation, as it does encode the type of all parameters, as well as array size,
constness, etc. So name mangling ensures type
safety.
