ATM_BROADBAND_BEARER_CAPABILITY_IE

構造体
サイズx64: 5 バイト / x86: 5 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
BearerClassBYTE1+0+0ベアラクラス(A/C/X等)を示す。
TrafficTypeBYTE1+1+1トラフィック種別(CBR/VBR等)を示す。
TimingRequirementsBYTE1+2+2送受信端点間のタイミング要件を示す。
ClippingSusceptabilityBYTE1+3+3クリッピング(欠落)許容度を示す。
UserPlaneConnectionConfigBYTE1+4+4ユーザープレーンの接続構成(ポイント間/マルチポイント)を示す。

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)
; ATM_BROADBAND_BEARER_CAPABILITY_IE サイズ: 5 バイト(x64)
dim st, 2    ; 4byte整数×2(構造体サイズ 5 / 4 切り上げ)
; BearerClass : BYTE (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; TrafficType : BYTE (+1, 1byte)  poke st,1,値  /  値 = peek(st,1)
; TimingRequirements : BYTE (+2, 1byte)  poke st,2,値  /  値 = peek(st,2)
; ClippingSusceptability : BYTE (+3, 1byte)  poke st,3,値  /  値 = peek(st,3)
; UserPlaneConnectionConfig : BYTE (+4, 1byte)  poke st,4,値  /  値 = peek(st,4)
; ※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。
