パラメーター

名前	型	方向	説明
hService	HANDLE	in	イベントを登録する対象のGATTサービスを表すハンドル。
EventType	BTH_LE_GATT_EVENT_TYPE	in	登録するイベントの種別を示す列挙値。特性値変更通知などを指定する。
EventParameterIn	void*	in	イベント種別に応じた入力パラメータ構造体へのポインタ。NULL可の場合がある。
Callback	PFNBLUETOOTH_GATT_EVENT_CALLBACK	in	イベント発生時に呼び出されるコールバック関数へのポインタ。
CallbackContext	void*	inoptional	コールバックへ引き渡される任意のユーザーコンテキスト。NULL可。
pEventHandle	INT_PTR*	out	登録したイベントを識別するハンドルを受け取る出力ポインタ。後の登録解除に使う。
Flags	DWORD	in	動作を制御するフラグ。通常は予約値として0を指定する。
