KSPROPERTY_STEPPING_LONG

構造体
サイズx64: 16 バイト / x86: 16 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
SteppingDeltaDWORD4+0+0値の刻み幅(増分)。32ビットプロパティの段階値を示す。
ReservedDWORD4+4+4予約領域。将来拡張用で通常は0とする。
BoundsKSPROPERTY_BOUNDS_LONG8+8+8値の下限/上限範囲(KSPROPERTY_BOUNDS_LONG)。許容範囲を示す。

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)
; KSPROPERTY_STEPPING_LONG サイズ: 16 バイト(x64)
dim st, 4    ; 4byte整数×4(構造体サイズ 16 / 4 切り上げ)
; SteppingDelta : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Reserved : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; Bounds : KSPROPERTY_BOUNDS_LONG (+8, 8byte)  varptr(st)+8 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。
#defstruct global KSPROPERTY_STEPPING_LONG
    #field int SteppingDelta
    #field int Reserved
    #field byte Bounds 8
#endstruct

stdim st, KSPROPERTY_STEPPING_LONG        ; NSTRUCT 変数を確保
st->SteppingDelta = 100
mes "SteppingDelta=" + st->SteppingDelta
; ※union フィールドは byte 列で確保(NSTRUCT は union 非対応)。必要に応じ手動でアクセス。
