SCOPE_MIB_INFO_V6

構造体
サイズx64: 40 バイト / x86: 40 バイト

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x64x86説明
SubnetDHCP_IPV6_ADDRESS16+0+0統計対象IPv6スコープのアドレスを保持する。
NumAddressesInuseULONGLONG8+16+16スコープ内で使用中のアドレス数を64ビットで示す。
NumAddressesFreeULONGLONG8+24+24スコープ内で空きのアドレス数を64ビットで示す。
NumPendingAdvertisesULONGLONG8+32+32応答待ちのアドバタイズ数を64ビットで示す。

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)
; SCOPE_MIB_INFO_V6 サイズ: 40 バイト(x64)
dim st, 10    ; 4byte整数×10(構造体サイズ 40 / 4 切り上げ)
; Subnet : DHCP_IPV6_ADDRESS (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; NumAddressesInuse : ULONGLONG (+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
; NumAddressesFree : ULONGLONG (+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
; NumPendingAdvertises : ULONGLONG (+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
; ※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)。
