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)
; UNIDRVINFO サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; dwSize : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; flGenFlags : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; wType : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; fCaps : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)
; wXRes : WORD (+12, 2byte)  wpoke st,12,値  /  値 = wpeek(st,12)
; wYRes : WORD (+14, 2byte)  wpoke st,14,値  /  値 = wpeek(st,14)
; sYAdjust : SHORT (+16, 2byte)  wpoke st,16,値  /  値 = wpeek(st,16)
; sYMoved : SHORT (+18, 2byte)  wpoke st,18,値  /  値 = wpeek(st,18)

; sShift : SHORT (+22, 2byte)  wpoke st,22,値  /  値 = wpeek(st,22)
; SelectFont : INVOC (+24, 8byte)  varptr(st)+24 を基点に操作(8byte:入れ子/配列)
; UnSelectFont : INVOC (+32, 8byte)  varptr(st)+32 を基点に操作(8byte:入れ子/配列)
; wReserved : WORD (+40, 8byte)  varptr(st)+40 を基点に操作(8byte: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。
