NVME_LBA_RANGE
構造体サイズ=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 |
|---|---|---|---|---|---|
| Attributes | NVME_CONTEXT_ATTRIBUTES | 4 | +0 | +0 | Dataset ManagementにおけるこのLBA範囲の使用方法を示すコンテキスト属性である。 |
| LogicalBlockCount | DWORD | 4 | +4 | +4 | この範囲に含まれる論理ブロック数を表す32ビット値である。 |
| StartingLBA | ULONGLONG | 8 | +8 | +8 | 範囲の開始論理ブロックアドレス(Starting LBA)を表す64ビット値である。 |

}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)
; NVME_LBA_RANGE 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)
; Attributes : NVME_CONTEXT_ATTRIBUTES (+0, 4byte) varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; LogicalBlockCount : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; StartingLBA : ULONGLONG (+8, 8byte) qpoke st,8,値 / qpeek(st,8) ※IronHSPのみ。3.7/3.8は lpoke st,8,下位 : lpoke st,12,上位
; ※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。
