CDROM_TOC_FULL_TOC_DATA

構造体

サイズx64: 15 バイト / x86: 15 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
Length	BYTE	2	+0	+0	フルTOCデータの長さをビッグエンディアン2バイトで示す。
FirstCompleteSession	BYTE	1	+2	+2	最初の完結セッション番号を示す。
LastCompleteSession	BYTE	1	+3	+3	最後の完結セッション番号を示す。
Descriptors	CDROM_TOC_FULL_TOC_DATA_BLOCK	11	+4	+4	フルTOCの各エントリを保持するCDROM_TOC_FULL_TOC_DATA_BLOCK配列。

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)
; CDROM_TOC_FULL_TOC_DATA サイズ: 15 バイト(x64)
dim st, 4    ; 4byte整数×4(構造体サイズ 15 / 4 切り上げ)
; Length : BYTE (+0, 2byte)  varptr(st)+0 を基点に操作(2byte:入れ子/配列)
; FirstCompleteSession : BYTE (+2, 1byte)  poke st,2,値  /  値 = peek(st,2)
; LastCompleteSession : BYTE (+3, 1byte)  poke st,3,値  /  値 = peek(st,3)
; Descriptors : CDROM_TOC_FULL_TOC_DATA_BLOCK (+4, 11byte)  varptr(st)+4 を基点に操作(11byte: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)。
