 number-of-bytes

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

    Number of contiguous bytes to be deallocated by LIB$FREE_VM_64.
    The number-of-bytes argument is the address of a signed quadword
    integer that contains this number. The value of number-of-bytes
    must be greater than zero.

    Byte counts are rounded in the same manner as in LIB$GET_VM_64.

                                   NOTE

       You may omit the number-of-bytes argument if you are using
       boundary tags (LIB$M_VM_BOUNDARY_TAGS).

 base-address

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

    Address of the first byte to be deallocated by LIB$FREE_VM_64.
    The base-address argument contains the address of an unsigned
    quadword that is this address. The value of base-address must be
    the address of a block of memory that was allocated by a previous
    call to LIB$GET_VM_64.

 zone-id

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

    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.

    You must specify the same zone-id value as when you called
    LIB$GET_VM_64 to allocate the block. An error status will
    be returned if you specify an incorrect zone-id. The zone-id
    argument is optional. If zone-id is omitted or if the quadword
    contains the value 0, the 64-bit default zone is used.
