+ * gtk_message_dialog_new_with_markup:
+ * @parent: transient parent, or %NULL for none 
+ * @flags: flags
+ * @type: type of message
+ * @buttons: set of buttons to use
+ * @message_format: printf()-style format string, or %NULL
+ * @Varargs: arguments for @message_format
+ * 
+ * Creates a new message dialog, which is a simple dialog with an icon
+ * indicating the dialog type (error, warning, etc.) and some text which
+ * is marked up with the <link linkend="PangoMarkupFormat">Pango text markup language</link>.
+ * When the user clicks a button a "response" signal is emitted with
+ * response IDs from #GtkResponseType. See #GtkDialog for more details.
+ *
+ * Please note that if you have strings in the printf() arguments
+ * passed to this function, you might need to protect against
+ * them being interpreted as markup. You can do this using
+ * g_markup_escape_text() as in the following example:
+ * <informalexample><programlisting>
+ *   const gchar *error_text =
+ *     "&lt;span weight=\"bold\" size=\"larger\"&gt;"
+ *     "Could not open document '%s'."
+ *     "&lt;/span&gt;\n\n"

+ *                                                GTK_MESSAGE_ERROR,

+ *                                                error_text, tmp);
+ *   g_free (tmp);
+ * </programlisting></informalexample>
+ * 
+ * Return value: a new #GtkMessageDialog
+ *
+ * Since: 2.4
