Convert QByteArray to uint8_t*(uint8_t array)

[kayakaan02]

How can I convert QByteArray coming from QFile::readAll() into a uint8_t array(uint8_t*)?

just the signdness doesn't match up, but you should be able to simply cast it, as it's the same size

As @J-Hilk has said, but you might use const char *QByteArray::constData() const for efficiency/safety, assuming you really want a const uint8_t*, since I imagine you will not be altering the data.
