CHANGER_READ_ELEMENT_STATUS

構造体
📘 Microsoft Learn (日本語) · English
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x64x86説明
ElementListCHANGER_ELEMENT_LIST12+0+0状態を取得する要素の範囲。CHANGER_ELEMENT_LIST構造体。
VolumeTagInfoBOOLEAN1+12+12ボリュームタグ情報を取得するかどうかを示す真偽値。

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)
; CHANGER_READ_ELEMENT_STATUS 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)
; ElementList : CHANGER_ELEMENT_LIST (+0, 12byte)  varptr(st)+0 を基点に操作(12byte:入れ子/配列)
; VolumeTagInfo : BOOLEAN (+12, 1byte)  poke st,12,値  /  値 = peek(st,12)
; ※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)。
