Arguments

 

zone-id

   OpenVMS usage:identifier
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by reference

   Zone identifier. The zone-id argument is the address of an
   unsigned quadword containing this identifier. Use zero to
   indicate the 64-bit default zone.
 

detail-level

   OpenVMS usage:quadword_signed
   type:         quadword (signed)
   access:       read only
   mechanism:    by reference

   An identifier code specifying the level of detail required
   by the user. The detail-level argument is the address of a
   signed quadword containing this code. The default is minimal
   information. The following are valid values for detail-level:

   0    zone-id and name
   1    zone-id, name, algorithm, flags, and size information
   2    zone-id, name, algorithm, flags, size information, cache
        information, and area summary
   3    zone-id, name, algorithm, flags, size information, cache
        information, area summary, and queue validation
 

user-action-procedure

   OpenVMS usage:procedure
   type:         procedure value
   access:       function call (before return)
   mechanism:    by value

   Optional user-supplied action routine called by LIB$SHOW_VM_
   ZONE_64. By default, LIB$SHOW_VM_ZONE_64 prints statistics
   to SYS$OUTPUT by means of LIB$PUT_OUTPUT. An action routine
   is useful when you want to return statistics to a file or, in
   general, to any location other than SYS$OUTPUT. If user-action-
   procedure fails, LIB$SHOW_VM_ZONE_64 terminates and returns a
   failure code. Success codes are ignored.
 

user-arg

   OpenVMS usage:user_arg
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by value

   Optional 64-bit value to be passed directly to the action routine
   without interpretation. That is, the contents of the argument
   list entry user-arg are copied to the argument list entry for
   user-action-procedure.
