       XmClipboardInquireFormat — A clipboard function that returns a
       specified format name

       #include <Xm/CutPaste.h>
       int XmClipboardInquireFormat (display, window, index, format_name_buf,
               buffer_len, copied_len)
               Display * display;
               Window  window;
               int     index;
               XtPointer       format_name_buf;
               unsigned long   buffer_len;
               unsigned long   * copied_len;

       XmClipboardInquireFormat returns a specified format name for the data
       item in the clipboard. If the name must be truncated, the function
       returns a warning status.

       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.

       index     Specifies which of the ordered format names to obtain. If
                 this index is greater than the number of formats for the data
                 item, this function returns a 0 (zero) in the copied_len

                 Specifies the buffer that receives the format name.

                 Specifies the number of bytes in the format name buffer.

                 Specifies the number of bytes in the data item copied to the
                 buffer.  If this argument equals 0 (zero), there is no nth
                 format for the data item.

                 The function was 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.

                 The data returned is truncated because the user did not
                 provide a buffer large enough to hold the data.

                 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
