Syntax
#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.
