EMI_METADATA_V2

構造体

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)。

フィールド

フィールド	型	サイズ	x64	x86	説明

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_V2 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)
; HardwareOEM : WCHAR (+0, 32byte)  varptr(st)+0 を基点に操作(32byte:入れ子/配列)
; HardwareModel : WCHAR (+32, 32byte)  varptr(st)+32 を基点に操作(32byte:入れ子/配列)
; HardwareRevision : WORD (+64, 2byte)  wpoke st,64,値  /  値 = wpeek(st,64)
; ChannelCount : WORD (+66, 2byte)  wpoke st,66,値  /  値 = wpeek(st,66)
; Channels : EMI_CHANNEL_V2 (+68, 8byte)  varptr(st)+68 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)。
