NVCACHE_REQUEST_BLOCK
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 |
|---|---|---|---|---|---|
| NRBSize | DWORD | 4 | +0 | +0 | この要求ブロックのバイトサイズ。 |
| Function | WORD | 2 | +4 | +4 | 実行するNVキャッシュ機能コード。 |
| NRBFlags | DWORD | 4 | +8 | +8 | 要求の動作フラグ。 |
| NRBStatus | DWORD | 4 | +12 | +12 | 要求完了後のステータス。 |
| Count | DWORD | 4 | +16 | +16 | 操作対象のセクター数等のカウント。 |
| LBA | ULONGLONG | 8 | +24 | +24 | 操作の起点となる論理ブロックアドレス。 |
| DataBufSize | DWORD | 4 | +32 | +32 | データバッファのバイトサイズ。 |
| NVCacheStatus | DWORD | 4 | +36 | +36 | NVキャッシュの状態値。 |
| NVCacheSubStatus | DWORD | 4 | +40 | +40 | NVキャッシュの詳細サブステータス値。 |

}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)
; NVCACHE_REQUEST_BLOCK サイズ: 48 バイト(x64)
dim st, 12 ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; NRBSize : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; Function : WORD (+4, 2byte) wpoke st,4,値 / 値 = wpeek(st,4)
; NRBFlags : DWORD (+8, 4byte) st.2 = 値 / 値 = st.2 (lpoke/lpeek も可)
; NRBStatus : DWORD (+12, 4byte) st.3 = 値 / 値 = st.3 (lpoke/lpeek も可)
; Count : DWORD (+16, 4byte) st.4 = 値 / 値 = st.4 (lpoke/lpeek も可)
; LBA : ULONGLONG (+24, 8byte) qpoke st,24,値 / qpeek(st,24) ※IronHSPのみ。3.7/3.8は lpoke st,24,下位 : lpoke st,28,上位
; DataBufSize : DWORD (+32, 4byte) st.8 = 値 / 値 = st.8 (lpoke/lpeek も可)
; NVCacheStatus : DWORD (+36, 4byte) st.9 = 値 / 値 = st.9 (lpoke/lpeek も可)
; NVCacheSubStatus : DWORD (+40, 4byte) st.10 = 値 / 値 = st.10 (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。
