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. 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.
 

retadr

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

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 $LCKPAG 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.
