       XmClipboardRetrieve — A clipboard function that retrieves a data item
       from the clipboard

       #include <Xm/CutPaste.h>
       int XmClipboardRetrieve (display, window, format_name,
               buffer, length, num_bytes, private_id)
               Display * display;
               Window  window;
               char    * format_name;
               XtPointer       buffer;
               unsigned long   length;
               unsigned long   * num_bytes;
               long    * private_id;

       XmClipboardRetrieve retrieves the current data item from clipboard
       storage. It returns a warning if the clipboard is locked, if there is
       no data on the clipboard, or if the data needs to be truncated because
       the buffer length is too short.

       Between a call to XmClipboardStartRetrieve and a call to
       XmClipboardEndRetrieve, multiple calls to XmClipboardRetrieve with the
       same format name result in data being incrementally copied from the
       clipboard until the data in that format has all been copied.

       The return value XmClipboardTruncate from calls to XmClipboardRetrieve
       indicates that more data remains to be copied in the given format.  It
       is recommended that any calls to the Inquire functions that the
       application needs to make to effect the copy from the clipboard be made
       between the call to XmClipboardStartRetrieve and the first call to
       XmClipboardRetrieve. This way, the application does not need to call
       XmClipboardLock and XmClipboardUnlock.

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

       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 of the
                 clipboard functions that it calls.

                 Specifies the name of a format in which the data is stored on
                 the clipboard.

       buffer    Specifies the buffer to which the application wants the
                 clipboard to copy the data.  The function allocates space to
                 hold the data returned into the buffer.  The application is
                 responsible for managing this allocated space.  The
                 application can recover this allocated space by calling

       length    Specifies the length of the application buffer.

       num_bytes Specifies the number of bytes of data copied into the
                 application buffer.

                 Specifies the private data stored with the data item by the
                 application that placed the data item on the clipboard. If
                 the application did not store private data with the data
                 item, this argument returns 0 (zero).

                 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 operation.

                 The data returned is truncated because the user did not
                 provide a buffer large enough to hold the data.

                 The function could not find data on the clipboard
                 corresponding to the format requested. This could occur
                 because the clipboard is empty; there is data on the
                 clipboard but not in the requested format; or the data in the
                 requested format was passed by name and is no longer
