previous call to XOpenDisplay or XtDisplay.
- Specifies the window ID of a widget that relates the application window to

ID to each of the clipboard functions that it calls.

- The function failed because the clipboard was locked by another
application. The application can continue to call the function again with
the same parameters until the lock goes away. This gives the application
