The Motif clipboard is not a clipboard manager, but xclipboard, or a more functional clipboard client would be. The newest ICCCM (2.0) spells this out. The basic process is that the clipboard manager: 1) Check to see if CLIPBOARD_MANAGER is owned by anyone, abort if it is. 2) Assert ownership of CLIPBOARD_MANAGER and CLIPBOARD 3) When the CLIPBOARD selection is lost, query new owner for data and then retake ownership of CLIPBOARD #3 is done until the application exists. What you do with the data is up to the application.
