KSM_BDA_SCAN_FILTER

構造体
サイズx64: 32 バイト / x86: 32 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

フィールド型サイズx64x86説明
MethodKSIDENTIFIER8+0+0Kernel Streamingメソッド識別子。スキャンフィルタ設定メソッドを指定する。
ulScanModulationTypeSizeDWORD4+8+8argbScanModulationTypesのバイト数。変調種別配列の長さを示す。
AnalogVideoStandardsULONGLONG8+16+16対象とするアナログ映像規格のビットマスク。NTSC/PAL等を組合せ指定する。
argbScanModulationTypesBYTE1+24+24スキャン対象の変調方式配列の先頭バイト。可変長データへのアンカー。

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)
; KSM_BDA_SCAN_FILTER サイズ: 32 バイト(x64)
dim st, 8    ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; Method : KSIDENTIFIER (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; ulScanModulationTypeSize : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; AnalogVideoStandards : ULONGLONG (+16, 8byte)  qpoke st,16,値 / qpeek(st,16)  ※IronHSPのみ。3.7/3.8は lpoke st,16,下位 : lpoke st,20,上位
; argbScanModulationTypes : BYTE (+24, 1byte)  varptr(st)+24 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)。
