XmClipboardLock(3X)					   XmClipboardLock(3X)

NAME
       XmClipboardLock - A clipboard function that locks the clipboard

SYNOPSIS
       #include <Xm/Xm.h> #include <Xm/CutPaste.h>

       int XmClipboardLock (display, window)
	       Display * display;
	       Window window;

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 XmClipboard‐
       EndRetrieve.

       If the clipboard is already locked by another application, XmClipboard‐
       Lock  returns  an error status.	Multiple calls to this function by the
       same application increases the lock level.  Specifies a pointer to  the
       Display	structure that was returned in a previous call to XOpenDisplay
       or XtDisplay.  Specifies a widget's window ID that relates the applica‐
       tion  window  to the clipboard.	The widget's window ID can be obtained
       by using XtWindow. The same application instance should pass  the  same
       window ID to each of the clipboard functions that it calls.

RETURN VALUE
       The  function is 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.
