パラメーター

名前	型	方向	説明
regexp	URegularExpression*	inout	パターンを区切り文字としてテキストを分割する正規表現オブジェクト。
destBuf	WORD*	inout	分割された各フィールド文字列を連結格納する出力バッファ。UTF-16配列を指す。
destCapacity	INT	in	destBufの容量（コード単位数）。
requiredCapacity	INT*	inout	必要な総容量（コード単位数）を受け取る出力先。容量不足の判定に使う。
destFields	WORD**	inout	各フィールド先頭へのポインタを受け取る配列。各要素がdestBuf内の文字列を指す。
destFieldsCapacity	INT	in	destFields配列の要素数。分割結果の最大フィールド数を制限する。
status	UErrorCode*	inout	ICUエラーコードの入出力ポインタ。事前にU_ZERO_ERRORへ初期化する。
