       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  XmClipboard-
       Retrieve. This way, the application does not need to call XmClipboardLock and XmClipboard-

       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  applica-
		 tion can recover this allocated space by calling XtFree.

       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 available.

       XmClipboardEndRetrieve(3),   XmClipboardLock(3),   XmClipboardStartCopy(3),   XmClipboard-
       StartRetrieve(3), and XmClipboardUnlock(3).
