c++intbyteid3

How do you read in a 3 byte size value as an integer in c++?

I'm reading in an id3 tag where the size of each frame is specified in 3 bytes. How would I be able to utilize this value as an int?

Solution

  • Read each byte and then put them together into your int:

    int id3 = byte0 + (byte1 << 8) + (byte2 << 16);

    Make sure to take endianness into account.
