DXCoreAdapterMemoryBudget
構造体サイズ=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 |
|---|---|---|---|---|---|
| budget | ULONGLONG | 8 | +0 | +0 | OSがアプリに割り当てたメモリ予算(バイト数)。 |
| currentUsage | ULONGLONG | 8 | +8 | +8 | アプリが現在使用しているメモリ量(バイト数)。 |
| availableForReservation | ULONGLONG | 8 | +16 | +16 | 予約可能なメモリの上限(バイト数)。 |
| currentReservation | ULONGLONG | 8 | +24 | +24 | 現在予約済みのメモリ量(バイト数)。 |

}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)
; DXCoreAdapterMemoryBudget 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)
; budget : ULONGLONG (+0, 8byte) qpoke st,0,値 / qpeek(st,0) ※IronHSPのみ。3.7/3.8は lpoke st,0,下位 : lpoke st,4,上位
; currentUsage : ULONGLONG (+8, 8byte) qpoke st,8,値 / qpeek(st,8) ※IronHSPのみ。3.7/3.8は lpoke st,8,下位 : lpoke st,12,上位
; availableForReservation : ULONGLONG (+16, 8byte) qpoke st,16,値 / qpeek(st,16) ※IronHSPのみ。3.7/3.8は lpoke st,16,下位 : lpoke st,20,上位
; currentReservation : ULONGLONG (+24, 8byte) qpoke st,24,値 / qpeek(st,24) ※IronHSPのみ。3.7/3.8は lpoke st,24,下位 : lpoke st,28,上位
; ※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。
