パラメーター

名前	型	方向	説明
prep	UStringPrepProfile*	in	前処理に用いる開いたStringPrepプロファイルを指す。
src	WORD*	in	前処理対象の入力UTF-16文字列を指す。
srcLength	INT	in	srcの長さをUChar単位で指定する。-1でNUL終端。
dest	WORD*	inout	前処理結果を格納するUTF-16出力バッファ。NULL可。
destCapacity	INT	in	destの容量をUChar単位で指定する。0で事前長取得。
options	INT	in	処理オプションビット。USPREP_ALLOW_UNASSIGNED等を指定する。
parseError	UParseError*	inout	解析エラー位置の詳細を受け取る構造体。NULL可。
status	UErrorCode*	inout	ICUエラーコードを入出力するポインタ。呼出前に成功値で初期化する。
