Arguments

 

routin_64

   OpenVMS usage:procedure
   type:         procedure value
   access:       call without stack unwinding
   mechanism:    by 32- or 64-bit reference
   Routine to be executed while the process is in kernel mode. The
   routin_64 argument is the 32- or 64-bit address of this routine.
 

arglst_64

   OpenVMS usage:arg_list
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by 32- or 64-bit reference
   Quadword argument list to be passed to the routine specified
   by the routin_64 argument. The routin_64 argument is the 32- or
   64-bit address of this routine.

   If the arglst value is nonzero and is not accessible as an
   address or if the routine is inaccessible, the service returns
   SS$_ACCVIO.

   Alpha and Integrity server systems require a pointer to a valid
   argument list or a value of 0 in the arglst_64 argument. This
   means that the arglst_64 argument, if nonzero, must contain
   an accessible virtual address for an argument list, the first
   quadword of which must be a number between 0 and 255 specifying
   the number of quadwords that follow it on the list.
