構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 76 バイト / x86: 76 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)
; EMI_METADATA_V1 サイズ: 76 バイト(x64)
dim st, 19    ; 4byte整数×19(構造体サイズ 76 / 4 切り上げ)
; MeasurementUnit : EMI_MEASUREMENT_UNIT (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; HardwareOEM : WCHAR (+4, 32byte)  varptr(st)+4 を基点に操作(32byte:入れ子/配列)
; HardwareModel : WCHAR (+36, 32byte)  varptr(st)+36 を基点に操作(32byte:入れ子/配列)
; HardwareRevision : WORD (+68, 2byte)  wpoke st,68,値  /  値 = wpeek(st,68)
; MeteredHardwareNameSize : WORD (+70, 2byte)  wpoke st,70,値  /  値 = wpeek(st,70)
; MeteredHardwareName : WCHAR (+72, 2byte)  varptr(st)+72 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。
