TRANSACTION_PROPERTIES_INFORMATION
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 |
|---|---|---|---|---|---|
| IsolationLevel | DWORD | 4 | +0 | +0 | トランザクションの分離レベルを示す値。現状は予約され0を指定する。 |
| IsolationFlags | DWORD | 4 | +4 | +4 | 分離動作を制御するフラグのビットマスク。 |
| Timeout | LONGLONG | 8 | +8 | +8 | トランザクションのタイムアウト時間。100ナノ秒単位のLONGLONGで指定する。 |
| Outcome | DWORD | 4 | +16 | +16 | トランザクションの最終結果(コミット/中止など)を示す値。 |
| DescriptionLength | DWORD | 4 | +20 | +20 | Descriptionに格納される説明文字列のバイト長。 |
| Description | WCHAR | 2 | +24 | +24 | トランザクションの説明文字列を表す可変長WCHAR配列の先頭。 |

}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)
; TRANSACTION_PROPERTIES_INFORMATION サイズ: 32 バイト(x64)
dim st, 8 ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; IsolationLevel : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; IsolationFlags : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; Timeout : LONGLONG (+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
; Outcome : DWORD (+16, 4byte) st.4 = 値 / 値 = st.4 (lpoke/lpeek も可)
; DescriptionLength : DWORD (+20, 4byte) st.5 = 値 / 値 = st.5 (lpoke/lpeek も可)
; Description : WCHAR (+24, 2byte) varptr(st)+24 を基点に操作(2byte: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。
