SYSTEMTIME

構造体
📘 Microsoft Learn (日本語) · English
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

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)
; SYSTEMTIME 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)
; wYear : WORD (+0, 2byte)  wpoke st,0,値  /  値 = wpeek(st,0)
; wMonth : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; wDayOfWeek : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; wDay : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; wHour : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; wMinute : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)
; wSecond : WORD (+12, 2byte)  wpoke st,12,値  /  値 = wpeek(st,12)
; wMilliseconds : WORD (+14, 2byte)  wpoke st,14,値  /  値 = wpeek(st,14)
; ※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。
