          #include <Xm/CutPaste.h>

          int XmClipboardInquireCount (display, window, count,
                    max_format_name_length)
               Display   * display;
               Window    window;
               int       * count;
               unsigned long* max_format_name_length;

     DESCRIPTION
          XmClipboardInquireCount returns the number of data item
          formats available for the data item in the clipboard.  This
          function also returns the maximum name-length for all
          formats in which the data item is stored.

          display
               Specifies a pointer to the Display structure that was
               returned in a previous call to XOpenDisplay or
               XtDisplay.

          window
               Specifies a widget's window ID that relates the
               application 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.

          count
               Returns the number of data item formats available for
               the data item in the clipboard.  If no formats are
               available, this argument equals zero.  The count
               includes the formats that were passed by name.

          max_format_name_length
               Specifies the maximum length of all format names for
               the data item in the clipboard.

     RETURN VALUE
          ClipboardSuccess
               The function is successful.

          ClipboardLocked
               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.

          ClipboardNoData
               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.
