パラメーター

名前型方向説明
eventMinDWORDinフックする最小のイベント定数。監視範囲の下限を示す。
eventMaxDWORDinフックする最大のイベント定数。監視範囲の上限を示す。
hmodWinEventProcHMODULEinoptional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。
pfnWinEventProcWINEVENTPROCin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。
idProcessDWORDin監視対象のプロセスID。全プロセス監視は0を指定する。
idThreadDWORDin監視対象のスレッドID。全スレッド監視は0を指定する。
dwFlagsDWORDinフックの動作を制御するフラグ(WINEVENT_INCONTEXT・WINEVENT_OUTOFCONTEXT等)。
