39 * Given an AUTH_MSG_APPL_ERR message, "in" and its length "in_length",
40 * return the error code from the message in "code" and the text in

44 * m_data->app_length points to the length of the error text
46 * If all goes well, return RD_AP_OK. If the version number
47 * is wrong, return RD_AP_VERSION, and if it's not an AUTH_MSG_APPL_ERR
