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)
; IMAGE_COR20_HEADER サイズ: 72 バイト(x64)
dim st, 18    ; 4byte整数×18(構造体サイズ 72 / 4 切り上げ)
; cb : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; MajorRuntimeVersion : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; MinorRuntimeVersion : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; MetaData : IMAGE_DATA_DIRECTORY (+8, 8byte)  varptr(st)+8 を基点に操作(8byte:入れ子/配列)
; Flags : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; Anonymous : _Anonymous_e__Union (+20, 4byte)  varptr(st)+20 を基点に操作(4byte:入れ子/配列)
; Resources : IMAGE_DATA_DIRECTORY (+24, 8byte)  varptr(st)+24 を基点に操作(8byte:入れ子/配列)
; StrongNameSignature : IMAGE_DATA_DIRECTORY (+32, 8byte)  varptr(st)+32 を基点に操作(8byte:入れ子/配列)
; CodeManagerTable : IMAGE_DATA_DIRECTORY (+40, 8byte)  varptr(st)+40 を基点に操作(8byte:入れ子/配列)
; VTableFixups : IMAGE_DATA_DIRECTORY (+48, 8byte)  varptr(st)+48 を基点に操作(8byte:入れ子/配列)
; ExportAddressTableJumps : IMAGE_DATA_DIRECTORY (+56, 8byte)  varptr(st)+56 を基点に操作(8byte:入れ子/配列)
; ManagedNativeHeader : IMAGE_DATA_DIRECTORY (+64, 8byte)  varptr(st)+64 を基点に操作(8byte: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。
; ※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)。
