Must be a * descendant of ::rb_cData, or 0 as ::rb_cData. * @param[in] ... Arbitrary number of `const char*`, terminated by * NULL. Each of which are the name of fields. * @exception rb_eArgError Duplicated field name. * @return The defined class. */ VALUE rb_data_define(VALUE super, ...); ``` -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
