パラメーター

名前	型	方向	説明
eventMin	DWORD	in	フックする最小のイベント定数。監視範囲の下限を示す。
eventMax	DWORD	in	フックする最大のイベント定数。監視範囲の上限を示す。
hmodWinEventProc	HMODULE	inoptional	コールバック関数を含むDLLのモジュールハンドル。インプロセス時に指定、それ以外はNULL。
pfnWinEventProc	WINEVENTPROC	in	イベント発生時に呼び出されるWINEVENTPROCコールバック関数へのポインター。
idProcess	DWORD	in	監視対象のプロセスID。全プロセス監視は0を指定する。
idThread	DWORD	in	監視対象のスレッドID。全スレッド監視は0を指定する。
dwFlags	DWORD	in	フックの動作を制御するフラグ(WINEVENT_INCONTEXT・WINEVENT_OUTOFCONTEXT等)。
