NAME
       XmClipboardInquireLength — A clipboard function that returns the length
       of the stored data

SYNOPSIS
       #include <Xm/CutPaste.h>
       int XmClipboardInquireLength (display, window, format_name, length)
	       Display * display;
	       Window  window;
	       char    * format_name;
	       unsigned long   * length;
       (void)

DESCRIPTION
       XmClipboardInquireLength returns the length of the data stored under  a
       specified  format name for the clipboard data item. If no data is found
       for the specified format, or if there is no item on the clipboard, this
       function returns a value of 0 (zero) in the length argument.

       Any format passed by name is assumed to have length passed in a call to
       XmClipboardCopy, even though the data has not yet been  transferred  to
       the clipboard in that format.

       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 applica‐
		 tion  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 func‐
		 tions that it calls.

       format_name
		 Specifies the name of the format for the data item.

       length	 Specifies the length of the next data item in	the  specified
		 format. This argument equals 0 (zero) if no data is found for
		 the specified format, or if there is no  item	on  the	 clip‐
		 board.

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.

       XmClipboardNoData
		 The function could not find data on the clipboard correspond‐
		 ing 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.

       XmClipboardCopy(3) and XmClipboardStartCopy(3).
