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 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.

       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 clipboard.

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 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.
