Adapters

構造体

サイズx64: 276 バイト / x86: 276 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
numAdapters	INT	4	+0	+0	システム内のアダプター総数。adapter配列の要素数。
adapter	Adapter	272	+4	+4	Adapter構造体の配列(可変長)。各表示アダプター情報を保持する。

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)
; Adapters サイズ: 276 バイト(x64)
dim st, 69    ; 4byte整数×69(構造体サイズ 276 / 4 切り上げ)
; numAdapters : INT (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; adapter : Adapter (+4, 272byte)  varptr(st)+4 を基点に操作(272byte: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)。
