XmClipboardLock(library call)											     XmClipboardLock(library call)

NAME

       XmClipboardLock -- A clipboard function that locks the clipboard

SYNOPSIS

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

DESCRIPTION

       XmClipboardLock	locks the clipboard from access by another application until XmClipboardUnlock is called. All clipboard functions lock and
       unlock the clipboard to prevent simultaneous 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 level.

       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.

RETURN

       XmClipboardSuccess
		 The function was successful.

       XmClipboardLocked
		 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.
