       XmClipboardLock -- A clipboard function that locks the clipboard

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

       XmClipboardLock	locks the clipboard from access by another application until XmClipboard-
       Unlock is called. All clipboard functions lock and unlock the clipboard to prevent  simul-
       taneous	access.  This  function  allows  the  application to keep the clipboard data from
       changing between calls to Inquire and other clipboard functions. The application does  not
       need to lock the clipboard between calls to XmClipboardStartCopy and XmClipboardEndCopy or
       to XmClipboardStartRetrieve and XmClipboardEndRetrieve.

       If the clipboard is already locked by  another  application,  XmClipboardLock  returns  an
       error  status.  Multiple  calls to this function by the same application increase the lock

       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.

		 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.

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