XmClipboardWithdrawFormat — A clipboard function that
indicates that the application no longer wants to supply a
data item

     #include <Xm/CutPaste.h>
int XmClipboardWithdrawFormat (display, window, data_id)
        Display * display;
        Window  window;
        long    data_id;

     XmClipboardWithdrawFormat indicates that the
application no longer supplies a data item to the clipboard
that the application had previously passed by name.

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

window    Specifies the window ID of a widget that relates
          the application window to the clipboard.  The
          widget’s window ID can be obtained through
          XtWindow.  The same application instance should
          pass the same window ID to each clipboard function
          it calls.

data_id   Specifies an identifying number assigned to the
          data item, that uniquely identifies the data item
          and the format. This was assigned to the item when
          it was originally passed by XmClipboardCopy.

          The function was 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

     XmClipboardCopy(3) and XmClipboardStartCopy(3).
