DEBUG_LAST_EVENT_INFO_EXCEPTION

構造体

サイズx64: 160 バイト / x86: 160 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	x64	x86	説明
ExceptionRecord	EXCEPTION_RECORD64	152	+0	+0	発生した例外の詳細を保持するEXCEPTION_RECORD64。
FirstChance	DWORD	4	+152	+152	第一機会例外かを示すフラグ（非0で第一機会）。

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)
; DEBUG_LAST_EVENT_INFO_EXCEPTION サイズ: 160 バイト(x64)
dim st, 40    ; 4byte整数×40(構造体サイズ 160 / 4 切り上げ)
; ExceptionRecord : EXCEPTION_RECORD64 (+0, 152byte)  varptr(st)+0 を基点に操作(152byte:入れ子/配列)
; FirstChance : DWORD (+152, 4byte)  st.38 = 値  /  値 = st.38   (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。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
