パラメーター

名前	型	方向	説明
formatter	UDateIntervalFormat*	in	書式化に用いる日時間隔書式化器のハンドル。
fromDate	DOUBLE	in	間隔の開始日時。1970年からのミリ秒(UDate)で指定する。
toDate	DOUBLE	in	間隔の終了日時。1970年からのミリ秒(UDate)で指定する。
result	WORD*	inout	書式化結果を書き込むUTF-16出力バッファ(WORD配列)。
resultCapacity	INT	in	resultバッファの容量(UChar単位)。0で必要長を取得する。
position	UFieldPosition*	inout	出力する書式フィールドの位置情報を受け取る構造体ポインタ。NULL可。
status	UErrorCode*	inout	エラーコードへのポインタ。呼び出し前に初期化する必要がある。
