Writing a C++ wrapper for a C library
- by stripes
I have a legacy C library, written in an OO type form. Typical functions are like:
LIB *lib_new();
void lib_free(LIB *lib);
int lib_add_option(LIB *lib, int flags);
void lib_change_name(LIB *lib, char *name);
I'd like to use this library in my C++ program, so I'm thinking a C++ wrapper is required.
The above would all seem to map to something like:
class LIB
{
public:
LIB();
~LIB();
int add_option(int flags);
void change_name(char *name);
...
};
I've never written a C++ wrapper round C before, and can't find much advice about it. Is this a good/typical/sensible approach to creating a C++/C wrapper?
