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. |
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. |
