Description
  XWithdrawWindow() informs the window manager that the specified window and its icon should be unmapped.  It unmaps the specified window and
  sends a synthetic UnmapNotify event to the root window of the specified screen.  Window managers may elect to receive this message and  may
  treat  it  as  a  request  to  change the window's state to withdrawn.  When a window is in the withdrawn state, neither its normal nor its
  iconic representation is visible.  XWithdrawWindow() returns a non-zero status if the UnmapNotify event is successfully sent; otherwise, it
  returns a zero status.

  For more information, see Volume One, Chapter 12, Interclient Communication.
