PRJ_PLACEHOLDER_INFO

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 344 バイト / x86: 344 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)
; PRJ_PLACEHOLDER_INFO サイズ: 344 バイト(x64)
dim st, 86    ; 4byte整数×86(構造体サイズ 344 / 4 切り上げ)
; FileBasicInfo : PRJ_FILE_BASIC_INFO (+0, 56byte)  varptr(st)+0 を基点に操作(56byte:入れ子/配列)
; EaInformation : _EaInformation_e__Struct (+56, 8byte)  varptr(st)+56 を基点に操作(8byte:入れ子/配列)
; SecurityInformation : _SecurityInformation_e__Struct (+64, 8byte)  varptr(st)+64 を基点に操作(8byte:入れ子/配列)
; StreamsInformation : _StreamsInformation_e__Struct (+72, 8byte)  varptr(st)+72 を基点に操作(8byte:入れ子/配列)
; VersionInfo : PRJ_PLACEHOLDER_VERSION_INFO (+80, 256byte)  varptr(st)+80 を基点に操作(256byte:入れ子/配列)
; VariableData : BYTE (+336, 1byte)  varptr(st)+336 を基点に操作(1byte: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)。
