How to read a binary file in Go

Question

I\'m completely new to Go and I\'m trying to read a binary file, either byte by byte or several bytes at a time. The documentation doesn\'t help much and I cannot find any t

Answer 1

This is what I use to read an entire binary file into memory

func RetrieveROM(filename string) ([]byte, error) {
    file, err := os.Open(filename)

    if err != nil {
        return nil, err
    }
    defer file.Close()

    stats, statsErr := file.Stat()
    if statsErr != nil {
        return nil, statsErr
    }

    var size int64 = stats.Size()
    bytes := make([]byte, size)

    bufr := bufio.NewReader(file)
    _,err = bufr.Read(bytes)

    return bytes, err
}
