Arguments

 

number-of-bytes

   OpenVMS usage:quadword_signed
   type:         quadword integer (signed)
   access:       read only
   mechanism:    by reference

   Number of contiguous bytes that LIB$GET_VM_64 allocates. The
   number-of-bytes argument is the address of a quadword integer
   containing the number of bytes. LIB$GET_VM_64 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
   minus 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:         quadword (unsigned)
   access:       write only
   mechanism:    by reference

   First virtual address of the contiguous block of bytes allocated
   by LIB$GET_VM_64. The base-address argument is the address of an
   unsigned quadword containing this base address.
 

zone-id

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

   The zone-id argument is the address of a quadword that contains a
   zone identifier created by a previous call to LIB$CREATE_VM_ZONE_
   64 or LIB$CREATE_USER_VM_ZONE_64. This argument is optional. If
   zone-id is omitted or if the quadword contains the value 0, the
   64-bit default zone is used.
