I would want to raise an exception as it's made in Python or Java --to finish the program with an error message--.
An error message could be returned to a parent function:
func readFile(filename string) (content string, err os.Error) {
content, err := ioutil.ReadFile(filename)
if err != nil {
return "", os.ErrorString("read " + filename + ": " + err)
}
return string(content), nil
}
but I want that it can be finished when the error is found. Would be correct the next one?
func readFile(filename string) (content string) {
content, err := ioutil.ReadFile(filename)
defer func() {
if err != nil {
panic(err)
}
}()
return string(content)
}
