FS_BPIO_RESULTS

構造体
サイズx64: 328 バイト / x86: 328 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x64x86説明
OpStatusDWORD4+0+0操作結果を示すNTSTATUSコード。成功時は0。
FailingDriverNameLenWORD2+4+4FailingDriverName文字列のバイト単位長さ。
FailingDriverNameWCHAR64+6+6失敗を引き起こしたドライバー名の可変長WCHAR文字列の先頭。
FailureReasonLenWORD2+70+70FailureReason文字列のバイト単位長さ。
FailureReasonWCHAR256+72+72失敗理由を説明する可変長WCHAR文字列の先頭。

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)
; FS_BPIO_RESULTS サイズ: 328 バイト(x64)
dim st, 82    ; 4byte整数×82(構造体サイズ 328 / 4 切り上げ)
; OpStatus : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; FailingDriverNameLen : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; FailingDriverName : WCHAR (+6, 64byte)  varptr(st)+6 を基点に操作(64byte:入れ子/配列)
; FailureReasonLen : WORD (+70, 2byte)  wpoke st,70,値  /  値 = wpeek(st,70)
; FailureReason : WCHAR (+72, 256byte)  varptr(st)+72 を基点に操作(256byte: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。
