RTM_ENTITY_INFO

構造体

サイズx64: 16 バイト / x86: 16 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	x64	x86	説明
RtmInstanceId	WORD	2	+0	+0	RTMのインスタンス識別子(WORD)。アドレスファミリごとのインスタンス。
AddressFamily	WORD	2	+2	+2	エンティティが扱うアドレスファミリを表すWORD(AF_INET等)。
EntityId	RTM_ENTITY_ID	8	+8	+8	エンティティを一意に識別するRTM_ENTITY_ID。

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)
; RTM_ENTITY_INFO サイズ: 16 バイト(x64)
dim st, 4    ; 4byte整数×4(構造体サイズ 16 / 4 切り上げ)
; RtmInstanceId : WORD (+0, 2byte)  wpoke st,0,値  /  値 = wpeek(st,0)
; AddressFamily : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; EntityId : RTM_ENTITY_ID (+8, 8byte)  varptr(st)+8 を基点に操作(8byte: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)。
#defstruct global RTM_ENTITY_ID
    #field byte Anonymous 8
#endstruct

#defstruct global RTM_ENTITY_INFO
    #field short RtmInstanceId
    #field short AddressFamily
    #field RTM_ENTITY_ID EntityId
#endstruct

stdim st, RTM_ENTITY_INFO        ; NSTRUCT 変数を確保
st->RtmInstanceId = 100
mes "RtmInstanceId=" + st->RtmInstanceId
