REQUEST_OPLOCK_OUTPUT_BUFFER

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 24 バイト / x86: 24 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
StructureVersionWORD2+0+0この出力構造体のバージョン番号。
StructureLengthWORD2+2+2この出力構造体の長さ(バイト)。
OriginalOplockLevelDWORD4+4+4ブレーク前に保持していた元のoplockレベル。
NewOplockLevelDWORD4+8+8ブレーク後の新しいoplockレベル。
FlagsDWORD4+12+12oplock応答の状態を示すフラグ。
AccessModeDWORD4+16+16ブレークを引き起こした要求のアクセスモード。
ShareModeWORD2+20+20ブレークを引き起こした要求の共有モード。

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)
; REQUEST_OPLOCK_OUTPUT_BUFFER 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)
; StructureVersion : WORD (+0, 2byte)  wpoke st,0,値  /  値 = wpeek(st,0)
; StructureLength : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; OriginalOplockLevel : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; NewOplockLevel : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; Flags : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; AccessMode : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; ShareMode : WORD (+20, 2byte)  wpoke st,20,値  /  値 = wpeek(st,20)
; ※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。
