パラメーター

名前	型	方向	説明
locale	LPCSTR	in	メッセージ書式化に用いるロケールの識別子文字列。
pattern	WORD*	in	プレースホルダを含むメッセージパターン(UTF-16)。
patternLength	INT	in	patternの長さ。-1でNUL終端として扱う。
result	WORD*	inout	書式化結果を書き込むUTF-16出力バッファ(WORD配列)。
resultLength	INT	in	resultバッファの容量(UChar単位)。0で必要長を取得する。
ap	CHAR*	inout	差し込む値を格納したva_list(可変引数リスト)へのポインタ。
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。
