名前	型	方向	説明
dtpg	void**	inout	対象のUDateTimePatternGeneratorハンドル。
skeleton	WORD*	in	希望するフィールド構成を表すスケルトン文字列。UTF-16配列。
length	INT	in	スケルトンの長さ(UTF-16単位)。-1でNUL終端として扱う。
options	UDateTimePatternMatchOptions	in	フィールド幅一致方針などを指定するオプションフラグの列挙値。
bestPattern	WORD*	inout	生成された最適パターンを受け取る出力バッファ。UTF-16配列。
capacity	INT	in	出力バッファの容量(UTF-16単位)。0で必要長の照会も可能。
pErrorCode	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。
