WHV_VP_EXIT_CONTEXT

構造体

サイズx64: 48 バイト / x86: 48 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)。

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)
; WHV_VP_EXIT_CONTEXT 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)
; ExecutionState : WHV_X64_VP_EXECUTION_STATE (+0, 2byte)  varptr(st)+0 を基点に操作(2byte:入れ子/配列)
; _bitfield : BYTE (+2, 1byte)  poke st,2,値  /  値 = peek(st,2)
; Reserved : BYTE (+3, 1byte)  poke st,3,値  /  値 = peek(st,3)
; Reserved2 : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; Cs : WHV_X64_SEGMENT_REGISTER (+8, 24byte)  varptr(st)+8 を基点に操作(24byte:入れ子/配列)
; Rip : ULONGLONG (+32, 8byte)  qpoke st,32,値 / qpeek(st,32)  ※IronHSPのみ。3.7/3.8は lpoke st,32,下位 : lpoke st,36,上位
; Rflags : ULONGLONG (+40, 8byte)  qpoke st,40,値 / qpeek(st,40)  ※IronHSPのみ。3.7/3.8は lpoke st,40,下位 : lpoke st,44,上位
; ※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。
