How to get length of QByteArray with binary data?

[Infinity]

I have to following code:

QByteArray value = "2ad6a8da948de3ae0b73f5660574cc459fe8ad35";
m_value = QByteArray(QByteArray::fromHex(value));
m_length = m_value.

If value contains a '\0' it will show the wrong value.

What is the clean way to get the length of the binary data in QByteArray?
