UErrorCode* status
);パラメーター
| 名前 | 型 | 方向 | 説明 |
|---|---|---|---|
| sc | USpoofChecker* | in | 対象のUSpoofCheckerへのポインター。 |
| id | LPCSTR | in | 検査対象の識別子を指すUTF-8文字列へのポインター。 |
| length | INT | in | 識別子のバイト長。NUL終端なら-1を指定可能。 |
| position | INT* | inout | 非推奨。常に-1を返す位置出力ポインター。NULL可。 |
| status | UErrorCode* | inout | ICUのエラーコードを入出力するUErrorCodeへのポインター。 |
