パラメーター

名前	型	方向	説明
lpSubKey	LPCWSTR	in	作成または開くサブキーの名前を指す文字列を指定する。
Reserved	DWORD	in	予約済みパラメータ。0を指定する必要がある。
lpClass	LPWSTR	inoptional	キーのクラス（オブジェクト型）を指す文字列を指定する。NULL可。
dwOptions	DWORD	in	キー作成オプションを指定する。REG_OPTION_NON_VOLATILE等のフラグ。
samDesired	DWORD	in	キーへの希望アクセス権を指定するアクセスマスク。KEY_WRITE等を指定する。
lpSecurityAttributes	SECURITY_ATTRIBUTES*	inoptional	キーのセキュリティ記述子を持つSECURITY_ATTRIBUTES構造体へのポインタ。NULL可。
phkResult	HKEY*	out	作成または開かれたキーのハンドルを受け取るHKEYへのポインタを指定する。
lpdwDisposition	DWORD*	out	キーが新規作成（REG_CREATED_NEW_KEY）か既存（REG_OPENED_EXISTING_KEY）かを受け取る。NULL可。
