Function Open

writer.go:50–58

Open is a high-level wrapper that takes a variadic number of URLs, opens or creates each of the specified resources, and combines them into a locked WriteSyncer. It also returns any error encountered and a function to close any opened files. Passing no URLs returns a no-op WriteSyncer. Zap handles

(paths ...string)

// os.Stdout and os.Stderr. When specified without a scheme, relative file
// paths also work.
func Open(paths ...string) (zapcore.WriteSyncer, func(), error) {
	writers, closeAll, err := open(paths)
	if err != nil {
		return nil, nil, err
	}

	writer := CombineWriteSyncers(writers...)
	return writer, closeAll, nil
}
