XmClipboardUndoCopy(3X)

     NAME
          XmClipboardUndoCopy - A clipboard function that deletes the
          last item placed on the clipboard

     SYNOPSIS
          #include <Xm/Xm.h>
          #include <Xm/CutPaste.h>

          int XmClipboardUndoCopy (display, window)
               Display   * display;
               Window    window;

     DESCRIPTION
          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.

          display
               Specifies a pointer to the Display structure that was
               returned in a previous call to XOpenDisplay or
               XtDisplay.

          window
               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.

     RETURN VALUE
          ClipboardSuccess
               The function is successful.

          ClipboardLocked
               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 operation.
