Adapter

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 272 バイト / x86: 272 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x64x86説明
AdapterNameWCHAR256+0+0ディスプレイアダプターの名称を表すワイド文字列。
numSourcesINT4+256+256このアダプターが持つソース数。sources配列の要素数。
sourcesSources12+260+260アダブターに属するSources構造体の配列(可変長)。

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)
; Adapter サイズ: 272 バイト(x64)
dim st, 68    ; 4byte整数×68(構造体サイズ 272 / 4 切り上げ)
; AdapterName : WCHAR (+0, 256byte)  varptr(st)+0 を基点に操作(256byte:入れ子/配列)
; numSources : INT (+256, 4byte)  st.64 = 値  /  値 = st.64   (lpoke/lpeek も可)
; sources : Sources (+260, 12byte)  varptr(st)+260 を基点に操作(12byte: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)。
#defstruct global Sources
    #field int sourceId
    #field int numTargets
    #field int aTargets 1
#endstruct

#defstruct global Adapter
    #field wchar AdapterName 128
    #field int numSources
    #field Sources sources 1
#endstruct

stdim st, Adapter        ; NSTRUCT 変数を確保
st->numSources = 100
mes "numSources=" + st->numSources
