パラメーター

名前	型	方向	説明
pattern	WORD*	in	検索する語句（パターン）。UTF-16コード単位（WORD）の配列を指す。
patternlength	INT	in	patternの長さ（コード単位数）。NUL終端文字列なら-1を指定できる。
text	WORD*	in	検索対象となるテキスト。UTF-16コード単位（WORD）の配列を指す。
textlength	INT	in	textの長さ（コード単位数）。NUL終端文字列なら-1を指定できる。
locale	LPCSTR	in	照合規則を決めるロケール名。ICUロケールIDを指定し、NULLで既定ロケール。
breakiter	UBreakIterator*	inout	一致境界を制限する文字区切りイテレータ。単語境界等を強制する。不要ならNULL可。
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。
