pi620_revision_query


      ViStatus pi620_revision_query (ViSession instrumentHandle,

                                     ViChar _VI_FAR driverRevision[],

                                     ViChar _VI_FAR instrumentRevision[]);


  Purpose


      This function returns the revision numbers of the instrument driver.

     

      This instrument does not contain firmware so the instr_rev parameter is

      not valid.  It only exists for compliance with the VXI Plug and Play

      specification.

     

      This function always returns the defined value VI_WARN_NSUP_REV_QUERY.
