In following code:
type JPGFile struct {
Exif_SOI [2]byte
Exif
}
type Exif struct { APP1Marker [2]byte APP1DataSize uint16 ExifHeader
[6]byte TIFFHeader[6]byte}
func ReadFile(filename string) (JPGFile, error) {
jpgFile := JPGFile{}
in, err := os.Open(filename)
defer in.Close()
if err != nil {
return jpgFile, err
}
binary.Read(in, binary.LittleEndian, &jpgFile)
return jpgFile, nil
}
*binary.Read* accepts "in" (os.File) as a reader, but if I pass the file as
a parameter to the function I get the (correct ) error message that "in" is
not a reader, as defined in the documentation: func Read(r *io.Reader*,
order ByteOrder, data interface{}) error
Or is this working as intended?
