    Default What does 15:9 Reserved mean?

    1) Reading INDETIFY DEVICE data documentation.
    Can you explain me what does "15:9 Reserved" mean?

    2) I need to read binary file with device identification parameters and to parse it. Can I do it using QByteArray?

    Usually something being "reserved" means it is not being used yet by the current version of a format.

    What the numbers mean really depends on the specification at hand.

    Could mean "at position 15 with a length of 9", for example.

    Yes.

    You can either use QFile::readAll() to get the full file content into a single byte array or use QFile::seek() to jump to a specific position and then use QFile::read() to read a number of bytes from that position onwards.

    Cheers,

    Hi, from my experience 15:9 are bit numbers, e.g. in a 16bit word this means the upper seven bits.
