SENDCMDINPARAMS

構造体

サイズx64: 33 バイト / x86: 33 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

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)
; SENDCMDINPARAMS サイズ: 33 バイト(x64)
dim st, 9    ; 4byte整数×9(構造体サイズ 33 / 4 切り上げ)
; cBufferSize : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; irDriveRegs : IDEREGS (+4, 8byte)  varptr(st)+4 を基点に操作(8byte:入れ子/配列)
; bDriveNumber : BYTE (+12, 1byte)  poke st,12,値  /  値 = peek(st,12)
; bReserved : BYTE (+13, 3byte)  varptr(st)+13 を基点に操作(3byte:入れ子/配列)
; dwReserved : DWORD (+16, 16byte)  varptr(st)+16 を基点に操作(16byte:入れ子/配列)
; bBuffer : BYTE (+32, 1byte)  varptr(st)+32 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)。
