CHANGER_SEND_VOLUME_TAG_INFORMATION

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 52 バイト / x86: 52 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)。

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_SEND_VOLUME_TAG_INFORMATION サイズ: 52 バイト(x64)
dim st, 13    ; 4byte整数×13(構造体サイズ 52 / 4 切り上げ)
; StartingElement : CHANGER_ELEMENT (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; ActionCode : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; VolumeIDTemplate : BYTE (+12, 40byte)  varptr(st)+12 を基点に操作(40byte: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)。
#defstruct global CHANGER_ELEMENT
    #field int ElementType
    #field int ElementAddress
#endstruct

#defstruct global CHANGER_SEND_VOLUME_TAG_INFORMATION
    #field CHANGER_ELEMENT StartingElement
    #field int ActionCode
    #field byte VolumeIDTemplate 40
#endstruct

stdim st, CHANGER_SEND_VOLUME_TAG_INFORMATION        ; NSTRUCT 変数を確保
