ISCSI_TARGET_PORTAL_GROUPW
構造体サイズ=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 | x64 | x86 | 説明 |
|---|---|---|---|---|---|
| Count | DWORD | 4 | +0 | +0 | Portals配列に格納されるポータル数。 |
| Portals | ISCSI_TARGET_PORTALW | 1026 | +4 | +4 | ポータルグループを構成するISCSI_TARGET_PORTALWの可変長配列(先頭1要素を宣言)。 |

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_TARGET_PORTAL_GROUPW サイズ: 1032 バイト(x64)
dim st, 258 ; 4byte整数×258(構造体サイズ 1032 / 4 切り上げ)
; Count : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; Portals : ISCSI_TARGET_PORTALW (+4, 1026byte) varptr(st)+4 を基点に操作(1026byte: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)。
