Hi, I’ve coded a Ruby C extension in which some exception classes are
created. However, those classes are not visible in Ruby itself.
This is, if for example I do a “irb”:
irb> require “myexten.so”
Then the exception classes don’t exist. But the functions in the C
extension can make use of them, raise them and so.
I create the classes as follows:
void Init_utils() {
…
// Create a exception XDMSURLParsingError.
class_error = rb_define_class(“MyProjectError”, rb_eStandardError);
class_url_parsing_error = rb_define_class(“URLParsingError”,
class_error);
}
Should I do something special to export these classes to Ruby? Of
course a workaround would be creating these classes also in Ruby, but
seems a bit “dirty” 
Thanks.
