int XmClipboardUndoCopy (display, window)
Display * display;
XmClipboardUndoCopy deletes the last item placed
on the clipboard if the item was placed there by an application with the passed display and window arguments. Any data
item deleted from the clipboard by the original call to XmClipboardCopy is restored. If the display or window IDs do not match the last copied item, no action is taken,
and this function has no effect.
Specifies a pointer to the Display
structure that was returned in a previous call to XOpenDisplay
Specifies a widget's window ID that relates the application
window to the clipboard. The widget's window ID can be obtained by using XtWindow. The same application instance should pass the same window
ID to each clipboard function it calls.
The function is successful.
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
the opportunity to ask if the user wants to keep trying or to give up on the
