Arguments

 

inadr

   OpenVMS usage:address_range
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Starting and ending virtual addresses of the range of pages to be
   locked in the working set. The inadr argument is the address of
   a 2-longword array containing, in order, the starting and ending
   process virtual addresses. Only the virtual page number portion
   of each virtual address is used; the low-order byte-within-page
   bits are ignored.

   On Alpha and Integrity server systems, if the first address in
   the 2-longword array is within an image mapped to your process,
   the entire image specified by the address is locked in the
   working set.

   Be sure to check calls to the SYS$LKWSET and SYS$LKWSET_64 system
   services for correct arguments. This affects only process-based
   code running above IPL2. Compiler and linker differences might
   cause your program layout to change from Alpha, resulting in
   incorrectly calculated starting and ending addresses for calls
   to SYS$LKWSET and SYS$LKWSET_64. Calling these services with
   incorrect arguments and then executing this code above IPL2 could
   cause PGFIPLHI bugchecks. Note that SYS$LKWSET and SYS$LKWSET_
   64 automatically lock linker-generated short data sections
   associated with code sections locked in the working set.
 

retadr

   OpenVMS usage:address_range
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference
   Starting and ending process virtual addresses of the range of
   pages actually locked by $LKWSET. The retadr argument is the
   address of a 2-longword array containing, in order, the starting
   and ending process virtual addresses.

   On Alpha and Integrity server systems, if the inadr argument
   specifies an address within an image mapped to your process,
   retadr specifies only one range of pages locked in the working
   set. Many ranges of pages might be locked.
 

acmode

   OpenVMS usage:access_mode
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Access mode to be associated with the pages to be locked. The
   acmode argument is a longword containing the access mode. The
   $PSLDEF macro defines the four access modes.

   The most privileged access mode used is the access mode of the
   caller. For the $LKWSET service to complete successfully, the
   resultant access mode must be equal to or more privileged than
   the access mode already associated with the pages to be locked.
