SYSTEM_POWER_LEVEL

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 24 バイト / x86: 24 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
EnableBOOLEAN1+0+0この電源レベルが有効かどうかを示すブール値。
SpareBYTE3+1+1アライメント用の予備バイト。
BatteryLevelDWORD4+4+4このレベルが発動するバッテリ残量。パーセントで表す。
PowerPolicyPOWER_ACTION_POLICY12+8+8このレベルで実行する電源アクションポリシー。
MinSystemStateSYSTEM_POWER_STATE4+20+20このレベルで移行する最小システム電源状態。

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)
; SYSTEM_POWER_LEVEL サイズ: 24 バイト(x64)
dim st, 6    ; 4byte整数×6(構造体サイズ 24 / 4 切り上げ)
; Enable : BOOLEAN (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; Spare : BYTE (+1, 3byte)  varptr(st)+1 を基点に操作(3byte:入れ子/配列)
; BatteryLevel : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; PowerPolicy : POWER_ACTION_POLICY (+8, 12byte)  varptr(st)+8 を基点に操作(12byte:入れ子/配列)
; MinSystemState : SYSTEM_POWER_STATE (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; ※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)。
