サイズx64: 4 バイト / x86: 4 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

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)
; NVME_CDW13_FEATURES サイズ: 4 バイト(x64)
dim st, 1    ; 4byte整数×1(構造体サイズ 4 / 4 切り上げ)
; HostMemoryBuffer : NVME_CDW13_FEATURE_HOST_MEMORY_BUFFER (+0, 4byte)  varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; AsUlong : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; ※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。
#defstruct global NVME_CDW13_FEATURES
    #field byte HostMemoryBuffer 4
    #field int AsUlong
#endstruct

stdim st, NVME_CDW13_FEATURES        ; NSTRUCT 変数を確保
st->AsUlong = 100
mes "AsUlong=" + st->AsUlong
; ※union フィールドは byte 列で確保(NSTRUCT は union 非対応)。必要に応じ手動でアクセス。
