IPSEC_SA_LIFETIME0

構造体
サイズx64: 12 バイト / x86: 12 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

フィールドサイズx64x86説明
lifetimeSecondsDWORD4+0+0SAの有効期間(秒単位)。
lifetimeKilobytesDWORD4+4+4SAの有効データ量(キロバイト単位)。
lifetimePacketsDWORD4+8+8SAの有効パケット数。

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)
; IPSEC_SA_LIFETIME0 サイズ: 12 バイト(x64)
dim st, 3    ; 4byte整数×3(構造体サイズ 12 / 4 切り上げ)
; lifetimeSeconds : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; lifetimeKilobytes : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; lifetimePackets : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (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。
