SENDCMDOUTPARAMS

構造体

サイズx64: 17 バイト / x86: 17 バイトパッキング1

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
cBufferSize	DWORD	4	+0	+0	bBufferのバイト単位のサイズ。
DriverStatus	DRIVERSTATUS	12	+4	+4	コマンド実行のドライバステータス。DRIVERSTATUS構造体。
bBuffer	BYTE	1	+16	+16	コマンドの出力データバッファ。可変長配列。

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)
; SENDCMDOUTPARAMS サイズ: 17 バイト(x64)
dim st, 5    ; 4byte整数×5(構造体サイズ 17 / 4 切り上げ)
; cBufferSize : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; DriverStatus : DRIVERSTATUS (+4, 12byte)  varptr(st)+4 を基点に操作(12byte:入れ子/配列)
; bBuffer : BYTE (+16, 1byte)  varptr(st)+16 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)。
