WHV_X64_IO_PORT_ACCESS_CONTEXT

構造体

サイズx64: 112 バイト / x86: 112 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
InstructionByteCount	BYTE	1	+0	+0	InstructionBytesに格納された命令バイト数を示すBYTEである。
Reserved	BYTE	3	+1	+1	予約フィールド。アライメント用で0とする。
InstructionBytes	BYTE	16	+4	+4	アクセスを発生させた命令のバイト列を示すBYTE配列である。
AccessInfo	WHV_X64_IO_PORT_ACCESS_INFO	4	+20	+20	I/Oポートアクセスの方向やサイズ等を示すWHV_X64_IO_PORT_ACCESS_INFOである。
PortNumber	WORD	2	+24	+24	アクセス対象のI/Oポート番号を示すWORDである。
Reserved2	WORD	6	+26	+26	予約フィールド。アライメント用で0とする。
Rax	ULONGLONG	8	+32	+32	アクセス時のRAXレジスタ値である。OUT/INのデータ等を保持する。
Rcx	ULONGLONG	8	+40	+40	アクセス時のRCXレジスタ値である。文字列I/Oのカウント等に使う。
Rsi	ULONGLONG	8	+48	+48	アクセス時のRSIレジスタ値である。文字列I/Oの送信元アドレス等に使う。
Rdi	ULONGLONG	8	+56	+56	アクセス時のRDIレジスタ値である。文字列I/Oの宛先アドレス等に使う。
