BDA_IPv4_ADDRESS_LIST

構造体
サイズx64: 8 バイト / x86: 8 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
ulcAddressesDWORD4+0+0rgAddresslに含まれるアドレス数を示す。
rgAddresslBDA_IPv4_ADDRESS4+4+4IPv4アドレスの配列を示すBDA_IPv4_ADDRESS。

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)
; BDA_IPv4_ADDRESS_LIST サイズ: 8 バイト(x64)
dim st, 2    ; 4byte整数×2(構造体サイズ 8 / 4 切り上げ)
; ulcAddresses : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; rgAddressl : BDA_IPv4_ADDRESS (+4, 4byte)  varptr(st)+4 を基点に操作(4byte: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 BDA_IPv4_ADDRESS
    #field byte rgbAddress 4
#endstruct

#defstruct global BDA_IPv4_ADDRESS_LIST
    #field int ulcAddresses
    #field BDA_IPv4_ADDRESS rgAddressl 1
#endstruct

stdim st, BDA_IPv4_ADDRESS_LIST        ; NSTRUCT 変数を確保
st->ulcAddresses = 100
