Arguments

 

pidctx

   OpenVMS usage:process_id
   type:         longword (unsigned)
   access:       modify
   mechanism:    by 32- or 64-bit reference (Alpha and Integrity
                 servers)
   Context value supplied by $PROCESS_SCAN to be used as the pidadr
   argument of $GETJPI. The pidctx argument is the 32- or 64-bit
   address (on Alpha and Integrity server systems) of a longword
   that is to receive the process context longword. This longword
   normally contains 0 or a previous context. If it contains a
   previous context, the old context is deleted. If it contains
   a value other than 0 or a previous context, the old value is
   ignored.
 

itmlst

   OpenVMS usage:32-bit item_list_3 or 64-bit item_list_64b
   type:         longword (unsigned) for 32-bit; quadword (unsigned)
                 for 64-bit
   access:       read only
   mechanism:    by 32- or 64-bit reference (Alpha and Integrity
                 servers)
   Item list specifying selection criteria to be used by the scan or
   to control the scan.

   The itmlst argument is the 32- or 64-bit address (on Alpha and
   Integrity server systems) of a list of item descriptors, each of
   which describes one selection criterion or control option. Within
   each selection criterion you can include several item entries. An
   item list in 32-bit format is terminated by a longword of 0; an
   item list in 64-bit format is terminated by a quadword of 0. All
   items in an item list must be of the same format-either 32-bit or
   64-bit.

   The information in the item list is passed to the item descriptor
   in one of two ways. If the item descriptor can always hold the
   actual value of the selection criterion, the value is placed in
   the second longword of the item descriptor and the buffer length
   is specified as 0. If the item descriptor points to the actual
   value of the selection criterion, the address of the value is
   placed in the second longword of the item descriptor and you must
   specify the buffer length for the selection criterion. Each item
   code description specifies whether the information is passed by
   value or by reference.
