XmClipboardInquireFormat — A clipboard function that returns a specified format name

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 argument.

       format_name_buf
                 Specifies the buffer that receives the format name.

       buffer_len
                 Specifies the number of bytes in the format name buffer.

       copied_len
                 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.

                                                                                     XmClipboardInquireFormat(3)

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.

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

       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.
