ARGUMENTS
  display
      Specifies the connection to the X server.

  owner
      Specifies the owner of the specified selection atom. You can pass a
      window or None.

  property
      Specifies the property name. You also can pass None.

  requestor
      Specifies the requestor.

  selection
      Specifies the selection atom.

  target
      Specifies the target atom.

  time
      Specifies the time. You can pass either a timestamp or CurrentTime.

DESCRIPTION
  The XSetSelectionOwner function changes the owner and last-change time for
  the specified selection and has no effect if the specified time is earlier
  than the current last-change time of the specified selection or is later
  than the current X server time. Otherwise, the last-change time is set to
  the specified time, with CurrentTime replaced by the current server time.
  If the owner window is specified as None, then the owner of the selection
  becomes None (that is, no owner). Otherwise, the owner of the selection
  becomes the client executing the request.

  If the new owner (whether a client or None) is not the same as the current
  owner of the selection and the current owner is not None, the current owner
  is sent a SelectionClear event. If the client that is the owner of a
  selection is later terminated (that is, its connection is closed) or if the
  owner window it has specified in the request is later destroyed, the owner
  of the selection automatically reverts to None, but the last-change time is
  not affected.	 The selection atom is uninterpreted by the X server.
  XGetSelectionOwner returns the owner window, which is reported in
  SelectionRequest and SelectionClear events. Selections are global to the X
  server.

  XSetSelectionOwner can generate BadAtom and BadWindow errors.

  The XGetSelectionOwner function returns the window ID associated with the
  window that currently owns the specified selection.  If no selection was
  specified, the function returns the constant None. If None is returned,
  there is no owner for the selection.

  XGetSelectionOwner can generate a BadAtom error.

  XConvertSelection requests that the specified selection be converted to the
  specified target type:

    ·  If the specified selection has an owner, the X server sends a
       SelectionRequest event to that owner.

    ·  If no owner for the specified selection exists, the X server generates
       a SelectionNotify event to the requestor with property None.

  The arguments are passed on unchanged in either of the events. There are
  two predefined selection atoms: PRIMARY and SECONDARY.

  XConvertSelection can generate BadAtom and BadWindow errors.

DIAGNOSTICS
  BadAtom A value for an Atom argument does not name a defined Atom.

  BadWindow
	  A value for a Window argument does not name a defined Window.
