$UPDSEC_64W_(Alpha_and_Integrity_servers)

   On Alpha and Integrity server systems, writes all modified pages
   in an active private or global disk file section back into the
   section file on disk. Zero or more I/O requests are queued, based
   on the number of pages that have been modified.

   The $UPDSEC_64W service completes synchronously; that is, it
   returns to the caller after writing all updated pages.

   In all other respects, $UPDSEC_64W is identical to $UPDSEC_64.
   For additional information about the $UPDSEC_64W service, see the
   help for $UPDSEC_64.

   This service accepts 64-bit addresses.
