       event_base  and  error_base  are  set  to the base event and error numbers, respectively.  Otherwise, the
       return value is FALSE, and the values of event_base and error_base are undefined.


RETURN VALUES
       TRUE           The DPMSQueryExtension function returns TRUE if the extension is available, and event_base
                      and  error_base  are set to the base event number and base error number for the extension,
                      respectively.

       FALSE          The DPMSQueryExtension function returns FALSE if  extension  is  not  available,  and  the
                      values of event_base and error_base are undefined.
