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)
; DISK_PERFORMANCE サイズ: 88 バイト(x64)
dim st, 22    ; 4byte整数×22(構造体サイズ 88 / 4 切り上げ)
; BytesRead : LONGLONG (+0, 8byte)  qpoke st,0,値 / qpeek(st,0)  ※IronHSPのみ。3.7/3.8は lpoke st,0,下位 : lpoke st,4,上位
; BytesWritten : 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
; ReadTime : 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
; WriteTime : 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
; IdleTime : LONGLONG (+32, 8byte)  qpoke st,32,値 / qpeek(st,32)  ※IronHSPのみ。3.7/3.8は lpoke st,32,下位 : lpoke st,36,上位
; ReadCount : DWORD (+40, 4byte)  st.10 = 値  /  値 = st.10   (lpoke/lpeek も可)
; WriteCount : DWORD (+44, 4byte)  st.11 = 値  /  値 = st.11   (lpoke/lpeek も可)
; QueueDepth : DWORD (+48, 4byte)  st.12 = 値  /  値 = st.12   (lpoke/lpeek も可)
; SplitCount : DWORD (+52, 4byte)  st.13 = 値  /  値 = st.13   (lpoke/lpeek も可)
; QueryTime : LONGLONG (+56, 8byte)  qpoke st,56,値 / qpeek(st,56)  ※IronHSPのみ。3.7/3.8は lpoke st,56,下位 : lpoke st,60,上位
; StorageDeviceNumber : DWORD (+64, 4byte)  st.16 = 値  /  値 = st.16   (lpoke/lpeek も可)
; StorageManagerName : WCHAR (+68, 16byte)  varptr(st)+68 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。
