open a file. func Open(name string) (file *File, err error) The following code uses os.Open to open a file. If an error occurs it calls log.Fatal to print the error message and stop.

f, err := os.Open("filename.ext") if err != nil { log.Fatal(err) } // do something with the open *File f You can get a lot done in Go knowing just this about the error type, but in this article we'll take a closer look at error and discuss some good practices for error handling in Go. The error type The error type is an interface type. An error variable acquisition module interface represents any value that can describe itself as a string. Here is the interface's declaration: type error interface { Error() string } The error type, as with all built in types, is predeclared in the universe block. The most commonly-used error implementation is the errors package's unexported errorString type. // errorString is a trivial implementation of error. type errorString struct { s string } func (e *errorString) Error() string { return e.s } You can construct one of these values with the errors.New function. It takes a string that it converts to an errors.errorString and returns as an error value. // New returns an error that formats as the given text. func New(text string) error { return &errorString{text} } Here's how you might use errors.New: func Sqrt(f float64) (float64, error) { if f < 0 { return 0, errors.New("math: square root of negative number") } // implementation } A caller passing a negative argument to Sqrt receives a non-nil error value (whose concrete representation is an errors.errorString value). The caller can access the error string ("math: square root of...") by calling the `error`'s Error method, or by just printing it: f, err := Sqrt(-1) if err != nil { fmt.P
