STORAGE_QUERY_DEPENDENT_VOLUME_LEV1_ENTRY

構造体
サイズx64: 32 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

EntryLengthDWORD4+0+0このエントリの長さ(バイト)。
DependencyTypeFlagsDWORD4+4+4依存関係の種別を示すフラグ。
ProviderSpecificFlagsDWORD4+8+8ストレージプロバイダ固有のフラグ。
VirtualStorageTypeVIRTUAL_STORAGE_TYPE20+12+12仮想ストレージの種別(VHD/VHDX等)を示す構造体。

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)
; STORAGE_QUERY_DEPENDENT_VOLUME_LEV1_ENTRY サイズ: 32 バイト(x64)
dim st, 8    ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; EntryLength : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; DependencyTypeFlags : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; ProviderSpecificFlags : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; VirtualStorageType : VIRTUAL_STORAGE_TYPE (+12, 20byte)  varptr(st)+12 を基点に操作(20byte: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 GUID, pack=1
    #field int Data1
    #field short Data2
    #field short Data3
