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)
; PERF_DATA_HEADER サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)
; dwTotalSize : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; dwNumCounters : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; PerfTimeStamp : LONGLONG (+8, 8byte)  qpoke st,8,値 / qpeek(st,8)  ※IronHSPのみ。3.7/3.8は lpoke st,8,下位 : lpoke st,12,上位
; PerfTime100NSec : LONGLONG (+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
; PerfFreq : LONGLONG (+24, 8byte)  qpoke st,24,値 / qpeek(st,24)  ※IronHSPのみ。3.7/3.8は lpoke st,24,下位 : lpoke st,28,上位
; SystemTime : SYSTEMTIME (+32, 16byte)  varptr(st)+32 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)。
