DHCP_RESERVED_SCOPE6

構造体
サイズx64: 32 バイト / x86: 32 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド型サイズx64x86説明
ReservedIpAddressDHCP_IPV6_ADDRESS16+0+0IPv6予約スコープの予約アドレスを保持する。
ReservedIpSubnetAddressDHCP_IPV6_ADDRESS16+16+16予約IPv6アドレスが属するサブネットアドレスを保持する。

HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; DHCP_RESERVED_SCOPE6 サイズ: 32 バイト(x64)
dim st, 8    ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; ReservedIpAddress : DHCP_IPV6_ADDRESS (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; ReservedIpSubnetAddress : DHCP_IPV6_ADDRESS (+16, 16byte)  varptr(st)+16 を基点に操作(16byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
#defstruct global DHCP_IPV6_ADDRESS
    #field int64 HighOrderBits
    #field int64 LowOrderBits
#endstruct

#defstruct global DHCP_RESERVED_SCOPE6
    #field DHCP_IPV6_ADDRESS ReservedIpAddress
    #field DHCP_IPV6_ADDRESS ReservedIpSubnetAddress
#endstruct

stdim st, DHCP_RESERVED_SCOPE6        ; NSTRUCT 変数を確保
