------------------------------------------------------------------------------
--  Display - Specifies the display to use.
--  Discard - Specifies True to cause all events up to the sync point to be
--            discarded.
--
-- Like X_Flush but in addition it waits until all events and errors resulting
-- from the flushed requests (or requests prior to the flushed events) have
-- returned from the server.  Discard tells us whether to discard all events
-- or not.  Error events are always passed to the Xlib error reporting routine.

------------------------------------------------------------------------------
--  Display - Specifies the display to use.
--  Onoff   - True to turn on synchronous behavior; False to turn it off.
--
-- Makes Xlib protocol message calls "synchronous".  No Xlib routine that
-- creates a protocol message to the server will return until the function
-- requested has been performed.  Turns the usage of the
-- X_Set_After_Function on and off.  Returns the current sync function.

------------------------------------------------------------------------------
--  Display - Specifies the display to use.
--  Funct   - Specifies the function to use.
--
-- Set the function that will be called after each and every server request
-- is queued.  The previous "after" function is returned.
