CLUSPROP_FILETIME

構造体

サイズx64: 16 バイト / x86: 16 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
Base	CLUSPROP_VALUE	8	+0	+0	プロパティ値ヘッダー。構文と値サイズを保持するCLUSPROP_VALUE構造体である。
ft	FILETIME	8	+8	+8	日時を表すFILETIME値である。1601年起点の100ナノ秒単位で格納する。

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)
; CLUSPROP_FILETIME サイズ: 16 バイト(x64)
dim st, 4    ; 4byte整数×4(構造体サイズ 16 / 4 切り上げ)
; Base : CLUSPROP_VALUE (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; ft : FILETIME (+8, 8byte)  varptr(st)+8 を基点に操作(8byte: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。
; ※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)。
