STORAGE_ACCESS_ALIGNMENT_DESCRIPTOR
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 |
|---|---|---|---|---|---|
| Version | DWORD | 4 | +0 | +0 | 構造体のバージョン番号。 |
| Size | DWORD | 4 | +4 | +4 | この構造体のサイズをバイト単位で示す。 |
| BytesPerCacheLine | DWORD | 4 | +8 | +8 | キャッシュラインあたりのバイト数。 |
| BytesOffsetForCacheAlignment | DWORD | 4 | +12 | +12 | キャッシュ整列のためのバイトオフセット。 |
| BytesPerLogicalSector | DWORD | 4 | +16 | +16 | 論理セクタあたりのバイト数。一般に512や4096。 |
| BytesPerPhysicalSector | DWORD | 4 | +20 | +20 | 物理セクタあたりのバイト数。4Kネイティブ等の判定に使う。 |
| BytesOffsetForSectorAlignment | DWORD | 4 | +24 | +24 | 物理セクタ整列のためのバイトオフセット。 |

}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)
; STORAGE_ACCESS_ALIGNMENT_DESCRIPTOR サイズ: 28 バイト(x64)
dim st, 7 ; 4byte整数×7(構造体サイズ 28 / 4 切り上げ)
; Version : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; Size : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; BytesPerCacheLine : DWORD (+8, 4byte) st.2 = 値 / 値 = st.2 (lpoke/lpeek も可)

; ※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。
