XSetSelectionOwner(display, selection, owner, time)
      Display *display;
      Atom selection;
      Window owner; 
      Time time;


display Specifies the connection to the X server.
selection Specifies the selection atom.
owner Specifies the owner of the specified selection atom. You can pass a window or None .
time Specifies the time. You can pass either a timestamp or CurrentTime.


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.


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.
