STORAGE_DEVICE_LOCATION_DESCRIPTOR

構造体
サイズx64: 40 バイト / x86: 32 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
VersionDWORD4+0+0構造体のバージョン番号。
SizeDWORD4+4+4この構造体全体のサイズをバイト単位で示す。
LocationDEVICE_LOCATION24/20+8+8デバイスの物理位置を示すDEVICE_LOCATION構造体。
StringOffsetDWORD4+32+28位置を表す文字列への本構造体先頭からのバイトオフセット。

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。(x86 レイアウト)

; ※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。
