CF_FS_METADATA

構造体

サイズx64: 48 バイト / x86: 48 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	x64	x86	説明
BasicInfo	FILE_BASIC_INFO	40	+0	+0	ファイルの基本情報(時刻・属性)を保持する構造体。
FileSize	LONGLONG	8	+40	+40	ファイルの論理サイズをバイトで表す。

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)
; CF_FS_METADATA サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; BasicInfo : FILE_BASIC_INFO (+0, 40byte)  varptr(st)+0 を基点に操作(40byte:入れ子/配列)
; FileSize : 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
; ※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)。
#defstruct global FILE_BASIC_INFO
    #field int64 CreationTime
