Types

type Event

type Event struct {
	Mask   uint32 // Mask of events
	Cookie uint32 // Unique cookie associating related events (for rename)
	Name   string // File name (optional)
}

Event is the type of the notification messages received on the watcher's Event channel.

func (*Event) String

func (e *Event) String() string

String formats the event e in the form "filename: 0xEventMask = FS_ACCESS|FS_ATTRIB_|..."

type Watcher

type Watcher struct {
	Event chan *Event // Events are returned on this channel
	Error chan error  // Errors are sent on this channel
	// contains filtered or unexported fields
}

A Watcher waits for and receives event notifications for a specific set of files and directories.

func NewWatcher

func NewWatcher() (*Watcher, error)

NewWatcher creates and returns a Watcher.

func (*Watcher) AddWatch

func (w *Watcher) AddWatch(path string, flags uint32) error

AddWatch adds path to the watched file set.

func (*Watcher) Close

Close closes a Watcher. It sends a message to the reader goroutine to quit and removes all watches associated with the watcher.

func (*Watcher) RemoveWatch

func (w *Watcher) RemoveWatch(path string) error

RemoveWatch removes path from the watched file set.

func (*Watcher) Watch

func (w *Watcher) Watch(path string) error
