パラメーター

名前	型	方向	説明
timeStyle	UDateFormatStyle	in	時刻部分の書式スタイルを示す列挙値。UDAT_NONEで時刻を省く。
dateStyle	UDateFormatStyle	in	日付部分の書式スタイルを示す列挙値。UDAT_PATTERNでパターン使用。
locale	LPCSTR	in	日付書式に用いるロケール名。NULLで既定ロケールを使用する。
tzID	WORD*	in	タイムゾーンID文字列。UTF-16配列。NULLで既定タイムゾーンを使う。
tzIDLength	INT	in	タイムゾーンIDの長さ(UTF-16単位)。-1でNUL終端として扱う。
pattern	WORD*	in	PATTERNスタイル時に使う日付書式パターン文字列。UTF-16配列。
patternLength	INT	in	パターンの長さ(UTF-16単位)。-1でNUL終端として扱う。
status	UErrorCode*	inout	ICUのエラーコード。呼び出し前に成功値で初期化する。
