NVM_SET_LIST

構造体

サイズx64: 256 バイト / x86: 256 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
IdentifierCount	BYTE	1	+0	+0	リストに含まれるNVMセット属性エントリの個数。
Reserved	BYTE	127	+1	+1	予約領域。将来拡張用で0とする。
Entry	NVME_SET_ATTRIBUTES_ENTRY	128	+128	+128	NVMセット属性エントリの配列。各要素は1つのセットを記述する。

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)
; NVM_SET_LIST サイズ: 256 バイト(x64)
dim st, 64    ; 4byte整数×64(構造体サイズ 256 / 4 切り上げ)
; IdentifierCount : BYTE (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; Reserved : BYTE (+1, 127byte)  varptr(st)+1 を基点に操作(127byte:入れ子/配列)
; Entry : NVME_SET_ATTRIBUTES_ENTRY (+128, 128byte)  varptr(st)+128 を基点に操作(128byte: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)。
