Subject: Adding a method to String class as Ruby C extension

Hi, I want to add a method to String class, and I want this method to
be defined in C.

In the C code, to add a method I must do:

  rb_define_method(myClass, "hello", hello, arg_count);

but I don't know how to set myClass to point to String class.


To create a new class I should do:

  VALUE myClass = rb_define_class_under(myModule, "MyClass", rb_cObject);

Since rb_cObject means Ruby Object class, could be rb_cString what I'm
looking for?

Thanks.
