DESCRIPTION
       The DPMSQueryExtension function queries the X server to  determine  the
       availability  of  the  Display Power Management Signaling (DPMS) Exten-
       sion.  If  the  extension  is  available,  it  returns  TRUE,  and  the
       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  exten-
                      sion  is not available, and the values of event_base and
                      error_base are undefined.
