extending an object

Gerardo Santana Gómez Garrido

I'm writing an extension for Ruby, and want to extend an object with
methods from a module. I'm doing it like this:

rb_extend_object(self, rb_mAModuleExtension);

But the methods added to self become private. I want them public. How
should this be done?

Thanks in advance.

I think rb_extend_object retains the original access of module instance
methods, so you should need to just define them public in the module
you're extending.

Thanks Ross, it's solved. For the record, I was using
rb_define_module_function insted of rb_define_method for defining a
method in the module.
