Struct nix::sys::inotify::Inotify

pub struct Inotify { /* fields omitted */ }

An inotify instance. This is also a file descriptor, you can feed it to other interfaces consuming file descriptors, epoll for example.

Implementations

impl Inotify

pub fn init(flags: InitFlags) -> Result<Inotify>

Initialize a new inotify instance.

Returns a Result containing an inotify instance.

For more information see, inotify_init(2).

pub fn add_watch<P: ?Sized + NixPath>(
    self,
    path: &P,
    mask: AddWatchFlags
) -> Result<WatchDescriptor>

Adds a new watch on the target file or directory.

Returns a watch descriptor. This is not a File Descriptor!

For more information see, inotify_add_watch(2).

pub fn rm_watch(self, wd: WatchDescriptor) -> Result<()>

Removes an existing watch using the watch descriptor returned by inotify_add_watch.

Returns an EINVAL error if the watch descriptor is invalid.

For more information see, inotify_rm_watch(2).

pub fn read_events(self) -> Result<Vec<InotifyEvent>>

Reads a collection of events from the inotify file descriptor. This call can either be blocking or non blocking depending on whether IN_NONBLOCK was set at initialization.

Returns as many events as available. If the call was non blocking and no events could be read then the EAGAIN error is returned.
