-- Display - the display to read from

-- Discard - True to discard any extra extra data that may appear with the
-- reply
-- Status - Failed if we got an Error instead of a Reply
--
-- Read a reply to a request out of the network connection. You should only
-- request multiples of 4 bytes.
--
-- The Wire_To_Reply procedure has these arguments.
--
-- Code - Specifies the X_Request_Code of the reply
-- Raw - Specifies the raw 32-bytes of data representing the reply
-- Send_Event - Specifies True if this reply was not sent by the server
-- Reply - Receives the converted reply record
-- Length - Specifies the number of additions words (groups of 4 bytes)
-- that make up the rest of the reply; including all variable
-- length data.
