Arguments

 

number-of-bytes

   OpenVMS usage:longword_signed
   type:         longword integer (signed)
   access:       read only
   mechanism:    by reference

   Number of contiguous bytes that LIB$GET_VM allocates. The number-
   of-bytes argument is the address of a longword integer containing
   the number of bytes. LIB$GET_VM allocates enough memory to
   satisfy the request. Your program should not reference an address
   before the first byte address allocated (base-address) or beyond
   the last byte allocated (base-address + number-of-bytes-1) since
   that space may be assigned to another routine. The value of
   number-of-bytes must be greater than zero.
 

base-address

   OpenVMS usage:address
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference

   First virtual address of the contiguous block of bytes allocated
   by LIB$GET_VM. The base-address argument is the address of an
   unsigned longword containing this base address.
 

zone-id

   OpenVMS usage:identifier
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   The zone-id argument is the address of a longword that contains a
   zone identifier created by a previous call to LIB$CREATE_VM_ZONE
   or LIB$CREATE_USER_VM_ZONE. This argument is optional. If zone-id
   is omitted or if the longword contains the value 0, the 32-bit
   default zone is used.
