Functions

func Close

func Close(err *error, closer io.Closer)

Close calls Close on the given Closer, and joins any error returned with the given error.

Use it inside a defer statement with a named return like this:

func foo() (err error) {
	f, err := os.Open("foo.txt")
	if err != nil {
		return err
	}
	defer errdefer.Close(&err, f)
	// ...
}
