Method: RDoc::Parser::C#find_class_comment

Defined in:
lib/rdoc/parser/c.rb

#find_class_comment(class_name, class_mod) ⇒ Object

Look for class or module documentation above Init_class_name(void), in a Document-class class_name (or module) comment or above an rb_define_class (or module). If a comment is supplied above a matching Init_ and a rb_define_class the Init_ comment is used.

/*
 * This is a comment for Foo
 */
Init_Foo(void) {
    VALUE cFoo = rb_define_class("Foo", rb_cObject);
}

/*
 * Document-class: Foo
 * This is a comment for Foo
 */
Init_foo(void) {
    VALUE cFoo = rb_define_class("Foo", rb_cObject);
}

/*
 * This is a comment for Foo
 */
VALUE cFoo = rb_define_class("Foo", rb_cObject);
