If #flags is used, flags is the numeric (integer) representation of the flags is to be set. If the # is omitted, flags is a list of symbolic flags. Currently, there is only one flag: multiple or noflush with the same meaning, indicating that there is more to follow and no automatic flush on the channel should be done.
