ICMPV6_ECHO_REPLY_LH

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 36 バイト / x86: 36 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
AddressIPV6_ADDRESS_EX26+0+0応答元ホストのIPv6アドレス情報を保持するIPV6_ADDRESS_EX構造体。
StatusDWORD4+28+28エコー要求の結果ステータス(IP_STATUS)を示す。0は成功。
RoundTripTimeDWORD4+32+32往復応答時間をミリ秒単位で示す。

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)
; ICMPV6_ECHO_REPLY_LH サイズ: 36 バイト(x64)
dim st, 9    ; 4byte整数×9(構造体サイズ 36 / 4 切り上げ)
; Address : IPV6_ADDRESS_EX (+0, 26byte)  varptr(st)+0 を基点に操作(26byte:入れ子/配列)
; Status : DWORD (+28, 4byte)  st.7 = 値  /  値 = st.7   (lpoke/lpeek も可)
; RoundTripTime : DWORD (+32, 4byte)  st.8 = 値  /  値 = st.8   (lpoke/lpeek も可)
; ※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)。
