package encoding/gob
Decode reads the next value from the input stream and stores it in the data represented by the empty interface value. If e (1st parameter) is nil, the value will be discarded. Otherwise, the value underlying e must be a pointer to the correct type for the next data item received. If the input is at EOF, Decode returns io.EOF and does not modify e.
Golang encoding/gob.Decoder.Decode() function usage example
type Item struct {
Data interface{}
Name string
}
func decode_gob(data []byte, output *Item) error {
buffer := bytes.NewBuffer(data)
decoder := gob.NewDecoder(buffer)
return decoder.Decode(&output) // <-- here
}
