}示例2: RetrieveCharacteristicsL
TInt CryptoSpiUtil::RetrieveCharacteristicsL(TInt32 aInterface, RDesReadStream& aStream, RBuf8& aBuf, TInt& aCount)
{
// first we are only trying to retrieve the length of the buffer

// testresult would be checked outside the loop
testResult = RProperty::Get(KCryptoSpiPropertyCat, aInterface, buf);
}
// overflow will occur as we are only retrieving the length first.
// any other error we should leave
if(testResult != KErrOverflow)
{
User::LeaveIfError(testResult);
}
//read the length
RDesReadStream rStream(buf);
