[Liberty-eiffel] Question about plugins

Hi all,

I need call a c function with char arguments. So I need convert STRING
object into chars. To do this I'm using two features, like these:

feature {}
   message (title: STRING; text: STRING)
      do
        int_message (title.to_external, text.to_external)
      end
                
   int_message (title: POINTER; text: POINTER)
      external "plug_in"
      alias "{
         location: "."
         module_name: "my_plugin"
         feature_name: "c_function"
         }"
      end
end

My question is: Is this the appropriate way? Or there is a more
easy/recommended way?

Thanks
Germán
