Pure Virtual

LuderForChrist · 07-07-2004, 08:08 AM

For those of who who have read/help out in my past thread, the C++ to C conversion is going great. But another challenge has arose!

I have a few firtual and many pure virtual functions in my C++ code.

Once I deleted the class and those functions in the public are open... can I just #include the file where the functions are declaired?

Once again thanks guys (and gals) !

Is there pure virtuals in C? If not (which I'm pretty sure I cant have them) how do I convert C++ pure virtuals and virtual functions to C functions?

no. C does not support classes. you can mimic the OOP idea by using structures and function points, ie:

Code:

struct foo {
    int (*foo_bar)(struct foo *);
    void (*foo_hoo)(struct foo *);
    int data;
    char *name;
....
};

struct foo bar;

   bar.data = 20;
   bar.name = "bla";
   bar.foo_hoo(&bar);
