REFS_SMR_VOLUME_GC_PARAMETERS

構造体
サイズx64: 88 バイト / x86: 88 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)。

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)
; REFS_SMR_VOLUME_GC_PARAMETERS サイズ: 88 バイト(x64)
dim st, 22    ; 4byte整数×22(構造体サイズ 88 / 4 切り上げ)
; Version : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Flags : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; Action : REFS_SMR_VOLUME_GC_ACTION (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; Method : REFS_SMR_VOLUME_GC_METHOD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; IoGranularity : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; CompressionFormat : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; Unused : ULONGLONG (+24, 64byte)  varptr(st)+24 を基点に操作(64byte: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。
