+ * function is called when a message is received with the corresponding request
+ * type, and posts a success or error response to the reply port.
+ *
+ * There is a close correspondence between functions here and the libarchive
+ * API. It's left up to the Dart code to present a more Darty API. As such,
+ * documentation of these functions is omitted, since it's available in the
+ * libarchive documentation.
