- * @Varargs: NULL-terminated list of tags to apply

*
* Inserts @text into @buffer at @iter, applying the list of tags to
- * the newly-inserted text. The last tag specified must be NULL to
+ * the newly-inserted text. The last tag specified must be %NULL to
* terminate the list. Equivalent to calling gtk_text_buffer_insert(),

* gtk_text_buffer_insert_with_tags() is just a convenience function.
* @text: UTF-8 text
* @len: length of @text, or -1
* @first_tag_name: name of a tag to apply to @text
- * @Varargs: more tag names
+ * @...: more tag names
*
* Same as gtk_text_buffer_insert_with_tags(), but allows you
* to pass in tag names instead of tag objects.
* @buffer: a #GtkTextBuffer
* @tag_name: (allow-none): name of the new tag, or %NULL
* @first_property_name: (allow-none): name of first property to set, or %NULL
- * @Varargs: %NULL-terminated list of property names and values
+ * @...: %NULL-terminated list of property names and values
*
* Creates a tag and adds it to the tag table for @buffer.
* Equivalent to calling gtk_text_tag_new() and then adding the
