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)
; NVME_PERSISTENT_EVENT_LOG_EVENT_HEADER サイズ: 24 バイト(x64)
dim st, 6    ; 4byte整数×6(構造体サイズ 24 / 4 切り上げ)
; EventType : BYTE (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; EventTypeRevision : BYTE (+1, 1byte)  poke st,1,値  /  値 = peek(st,1)
; EventHeaderLength : BYTE (+2, 1byte)  poke st,2,値  /  値 = peek(st,2)
; Reserved0 : BYTE (+3, 1byte)  poke st,3,値  /  値 = peek(st,3)
; ControllerIdentifier : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; EventTimestamp : ULONGLONG (+6, 8byte)  qpoke st,6,値 / qpeek(st,6)  ※IronHSPのみ。3.7/3.8は lpoke st,6,下位 : lpoke st,10,上位
; Reserved1 : BYTE (+14, 6byte)  varptr(st)+14 を基点に操作(6byte:入れ子/配列)
; VendorSpecificInformationLength : WORD (+20, 2byte)  wpoke st,20,値  /  値 = wpeek(st,20)
; EventLength : WORD (+22, 2byte)  wpoke st,22,値  /  値 = wpeek(st,22)
; ※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。
