 I decided to give object oriented programming a shot using only C (no C++) with this library, of course, it still compiles with C++ compilers such as in the Arduino IDE. Using C structs and function pointers, the library creates RingBuf objects that are complete with their own methods and attributes. Note that every method (except constructor), takes a `RingBuf *self` pointer. This is the equivalent of the `this` pointer in C++, but the C++ compiler automatically passes it behind the scenes. For this library, you must manually pass a the `RingBuf *self` pointer as the first argument.

-Fine. I reluctantly wrapped the C in a C++ class called `RingBufC`. All the methods are the same, except you no longer have to pass the this/self pointer. You can use either.

 ```
 // If you want to use C...

+char *mystr = "I like C";
 RingBuf *buf = RingBuf_new(sizeof(char*), 100);
-buf->add(buf, "I like C.");
+buf->add(buf, &mystr);
 ```

 // If you want to use the C++ wrapper

 RingBufC buf(sizeof(char*), 100);
-buf.add("C++ has pretty object.method() syntax");
+buf.add(&mystr);
