FILE_FULL_DIR_INFO

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 72 バイト / x86: 72 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

ChangeTimeLONGLONG8+32+32ファイルメタデータの最終変更時刻。
EndOfFileLONGLONG8+40+40ファイル末尾位置すなわち実サイズ(バイト)。
AllocationSizeLONGLONG8+48+48ファイルに割り当てられたサイズ(バイト)。

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)
; FILE_FULL_DIR_INFO サイズ: 72 バイト(x64)
dim st, 18    ; 4byte整数×18(構造体サイズ 72 / 4 切り上げ)
; NextEntryOffset : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; FileIndex : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; CreationTime : LONGLONG (+8, 8byte)  qpoke st,8,値 / qpeek(st,8)  ※IronHSPのみ。3.7/3.8は lpoke st,8,下位 : lpoke st,12,上位
; LastAccessTime : LONGLONG (+16, 8byte)  qpoke st,16,値 / qpeek(st,16)  ※IronHSPのみ。3.7/3.8は lpoke st,16,下位 : lpoke st,20,上位
; LastWriteTime : LONGLONG (+24, 8byte)  qpoke st,24,値 / qpeek(st,24)  ※IronHSPのみ。3.7/3.8は lpoke st,24,下位 : lpoke st,28,上位
; ChangeTime : LONGLONG (+32, 8byte)  qpoke st,32,値 / qpeek(st,32)  ※IronHSPのみ。3.7/3.8は lpoke st,32,下位 : lpoke st,36,上位
; EndOfFile : LONGLONG (+40, 8byte)  qpoke st,40,値 / qpeek(st,40)  ※IronHSPのみ。3.7/3.8は lpoke st,40,下位 : lpoke st,44,上位
; AllocationSize : LONGLONG (+48, 8byte)  qpoke st,48,値 / qpeek(st,48)  ※IronHSPのみ。3.7/3.8は lpoke st,48,下位 : lpoke st,52,上位
; FileAttributes : DWORD (+56, 4byte)  st.14 = 値  /  値 = st.14   (lpoke/lpeek も可)
; FileNameLength : DWORD (+60, 4byte)  st.15 = 値  /  値 = st.15   (lpoke/lpeek も可)
; EaSize : DWORD (+64, 4byte)  st.16 = 値  /  値 = st.16   (lpoke/lpeek も可)
; FileName : WCHAR (+68, 2byte)  varptr(st)+68 を基点に操作(2byte: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。
