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)
; OPM_CONNECTED_HDCP_DEVICE_INFORMATION サイズ: 72 バイト(x64)
dim st, 18    ; 4byte整数×18(構造体サイズ 72 / 4 切り上げ)
; rnRandomNumber : OPM_RANDOM_NUMBER (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; ulStatusFlags : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; ulHDCPFlags : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; ksvB : OPM_HDCP_KEY_SELECTION_VECTOR (+24, 5byte)  varptr(st)+24 を基点に操作(5byte:入れ子/配列)
; Reserved : BYTE (+29, 11byte)  varptr(st)+29 を基点に操作(11byte:入れ子/配列)
; Reserved2 : BYTE (+40, 16byte)  varptr(st)+40 を基点に操作(16byte:入れ子/配列)
; Reserved3 : BYTE (+56, 16byte)  varptr(st)+56 を基点に操作(16byte: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)。
