Arguments

 

inadr

   OpenVMS usage:address_range
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Address of a 2-longword array containing the starting and ending
   virtual addresses of the pages to be created. If the starting and
   ending virtual addresses are the same, a single page is created.
   The addresses are adjusted up or down to fall on CPU-specific
   page boundaries. Only the virtual page number portion of the
   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-array reference or descriptor
   Address of a 2-longword array to receive the starting and ending
   virtual addresses of the pages created.

   On Alpha and Integrity server systems, the retadr argument should
   be checked by programs for actual allocation. Because the Alpha
   and Integrity servers architectures define more than one page
   size, more space might be created than was specified in the inadr
   argument.
 

acmode

   OpenVMS usage:access_mode
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Access mode and protection for the new pages. The acmode argument
   is a longword containing the access mode.

   The $PSLDEF macro defines the following symbols for the four
   access modes:
 

   Symbol         Access Mode

   PSL$C_KERNEL   Kernel
   PSL$C_EXEC     Executive
   PSL$C_SUPER    Supervisor
   PSL$C_USER     User

   The most privileged access mode used is the access mode of
   the caller. The protection of the pages is read/write for the
   resultant access mode and those more privileged.
