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)
; FILE_QUERY_ON_DISK_VOL_INFO_BUFFER サイズ: 336 バイト(x64)
dim st, 84    ; 4byte整数×84(構造体サイズ 336 / 4 切り上げ)
; DirectoryCount : 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
; FileCount : 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
; FsFormatMajVersion : WORD (+16, 2byte)  wpoke st,16,値  /  値 = wpeek(st,16)
; FsFormatMinVersion : WORD (+18, 2byte)  wpoke st,18,値  /  値 = wpeek(st,18)
; FsFormatName : WCHAR (+20, 24byte)  varptr(st)+20 を基点に操作(24byte:入れ子/配列)
; FormatTime : LONGLONG (+48, 8byte)  qpoke st,48,値 / qpeek(st,48)  ※IronHSPのみ。3.7/3.8は lpoke st,48,下位 : lpoke st,52,上位
; LastUpdateTime : 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
; CopyrightInfo : WCHAR (+64, 68byte)  varptr(st)+64 を基点に操作(68byte:入れ子/配列)
; AbstractInfo : WCHAR (+132, 68byte)  varptr(st)+132 を基点に操作(68byte:入れ子/配列)
; FormattingImplementationInfo : WCHAR (+200, 68byte)  varptr(st)+200 を基点に操作(68byte:入れ子/配列)
; LastModifyingImplementationInfo : WCHAR (+268, 68byte)  varptr(st)+268 を基点に操作(68byte: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。
