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)
; ISCSI_DEVICE_ON_SESSIONW サイズ: 2040 バイト(x64)
dim st, 510    ; 4byte整数×510(構造体サイズ 2040 / 4 切り上げ)
; InitiatorName : WCHAR (+0, 512byte)  varptr(st)+0 を基点に操作(512byte:入れ子/配列)
; TargetName : WCHAR (+512, 448byte)  varptr(st)+512 を基点に操作(448byte:入れ子/配列)
; ScsiAddress : SCSI_ADDRESS (+960, 8byte)  varptr(st)+960 を基点に操作(8byte:入れ子/配列)
; DeviceInterfaceType : GUID (+968, 16byte)  varptr(st)+968 を基点に操作(16byte:入れ子/配列)
; DeviceInterfaceName : WCHAR (+984, 520byte)  varptr(st)+984 を基点に操作(520byte:入れ子/配列)
; LegacyName : WCHAR (+1504, 520byte)  varptr(st)+1504 を基点に操作(520byte:入れ子/配列)
; StorageDeviceNumber : STORAGE_DEVICE_NUMBER (+2024, 12byte)  varptr(st)+2024 を基点に操作(12byte:入れ子/配列)
; DeviceInstance : DWORD (+2036, 4byte)  st.509 = 値  /  値 = st.509   (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)。
